Knowledge maintenance ledger
A source of truth has to show when its own review work is due. This ledger is generated from the same dates, paths, gaps and screening states as the public research system.
This is maintenance inventory, not a confidence score. It does not monitor journals automatically, prove completeness or make a topic current merely because a date has not passed.

Publication correction, retraction and version audit
A live broad bibliographic query returned 281 Crossref works. Canonical evidence-record DOI values were normalized and intersected with those results; matched items were inspected for update-to metadata and preprint relationships.
Zero registered updates is not an all-clear. No registered update in the matched response does not prove that no correction, retraction, expression of concern, withdrawal or in-place revision exists.
| Status | Records | Meaning |
|---|
| Matched in dated Crossref query | 113 | The canonical DOI appeared in the dated broad query and carried no registered update in that response. This is a metadata observation, not proof that the work has never changed. |
|---|
| Canonical DOI outside query result | 27 | The record has a canonical DOI but did not appear in the broad Neocaridina query. It requires DOI-specific or alternative-registry status review before any no-update statement. |
|---|
| Preprint, version-sensitive | 1 | The evidence record is explicitly a preprint. Its version and later-publication status require direct monitoring; preprint review is not journal peer review. |
|---|
| No canonical DOI in registry | 7 | The evidence record uses another stable source URL. Crossref DOI update metadata cannot audit it. |

DOI records requiring narrower status review
Published records with registered preprint relationships
Audit limitations
- The query is a dated live result, not a retained raw Crossref response or a complete scholarly index.
- No registered update in the matched response does not prove that no correction, retraction, expression of concern, withdrawal or in-place revision exists.
- Crossref update visibility depends on publisher deposits and Retraction Watch coverage; some DOI agencies and all non-DOI sources require other checks.
- A broad bibliographic query can omit a valid DOI because its indexed title or metadata does not contain the search term.
- A preprint relationship identifies publication lineage, not independent replication or equivalence between versions.
Correction propagation audit
Every evidence record has a derived list of public consumers. Exact candidate-source matches also reach the dated search, current gap boundary and answerability brief. A source change is complete only after curated wording is reviewed, generated surfaces pass parity checks and cited historical records receive a follow-up decision.
| Propagation mode | Paths | Boundary |
|---|
| Editorial review required | 1057 | This curated wording or synthesis must be reconsidered when the source boundary changes. A passing generator test cannot decide the new scientific meaning. |
|---|
| Generated from governing registry | 2416 | This surface derives from a governing registry and should update with it, but release tests must still prove parity and routing. |
|---|
| Historical record needs follow-up decision | 95 | Do not silently rewrite history. Decide whether the prior change record remains accurate and publish a new correction or scope note when needed. |
|---|
Evidence records without a review-required public consumer: 0. Zero means every current record reaches at least one curated guide; it does not mean every affected sentence has already been reconsidered after a future correction.

- Influences of the diurnal cycle on gut microbiota in the Chinese swamp shrimp (Neocaridina denticulata) (2023). Adds a direct four-time gut-microbiota series while separating 16 sequencing samples from 600 source animals, descriptive diversity from a feeding schedule and bacterial genera from disease.
Next: The official Taylor and Francis record authenticates this 13-page article, published online 29 July 2022 in the 2023 issue, but the complete article remains access-controlled. Preserve only the abstract-reported scope: gut material from 600 Chinese swamp shrimp was sampled at 06:00, 12:00, 18:00 and 24:00 for 16S sequencing, with descriptive richness and diversity highest at 24:00, predicted digestion and absorption pathways reported as enriched, and Flavobacterium, Acinetobacter and Pseudomonas discussed as opportunistic pathogens. The official CC BY Figshare supplement, https://doi.org/10.6084/m9.figshare.20402326, contains two figures and two workbooks. Figure S1 visibly contains four sample points per time and reports no significant pairwise alpha-diversity comparison: Chao1, Shannon, Simpson and observed-species p values all range from 0.13 to 0.83. Figure S2 shows 16 rarefaction curves, four per time. Sixteen visible sequencing samples are not 600 independent microbial replicates, and a descriptively higher midnight value is not a supported time optimum. The open material does not establish how many guts formed each library, independent tank allocation, feeding schedule, light and temperature history, dissection and extraction controls, absolute bacterial load, beta-diversity model, multiplicity, pathway-prediction method or raw-sequence accession. The two official supplemental workbooks were checksum-verified but not audited because the bundled spreadsheet runtime did not initialize. Full text is required to verify source and taxon identity, tank structure, acclimation, animal-to-library construction, primers and region, sequencing, bioinformatics, controls, statistical unit and functional inference. Do not infer an endogenous circadian rhythm, best feeding hour, nocturnal care rule, measured digestion or absorption, infection, virulence, host disease, probiotic need, medication need or absolute bacterial abundance from the abstract or supplement. This DOI was one of the frozen census unmatched title records and is now a documented abstract-and-supplement decision, not evidence or a guide source. - Chromatosomes in Three Phenotypes of Neocaridina denticulata Kemp, 1918: Morphological and Chromatic Differences Measured Non-Invasively (2011). Could add a direct non-invasive colour-observation method while separating an anatomical imaging site from commercial grade, colour stability and husbandry claims.
Next: The official Oxford Academic record authenticates this eight-page 2011 Journal of Crustacean Biology article and exposes its abstract, but labels the article as access-controlled and the direct PDF request returned HTTP 403. Preserve only the abstract-reported scope: three phenotypes of Neocaridina denticulata under 2 cm differed in epidermal chromatosome quantity and dispersal, pigmentation was most pronounced in anterior body parts, and the uropod exopod was proposed as the most suitable area for non-invasive colour monitoring. Full text is required to verify phenotype names, animal source and identity, animal and holding-unit counts, sex, age, size distribution, molt and reproductive state, acclimation, background, light, camera and microscope settings, body regions, repeated observations, chromatosome counting and dispersal scales, calibration, blinding, statistical model, raw denominators, effect sizes and uncertainty. Do not infer a commercial grade, inheritance or genotype, health state, diet effect, preferred background, colour permanence, seller standard or phone-photo diagnostic. A suggested imaging site is not proof that one photograph measures a stable whole-animal phenotype. This DOI was one of the frozen census unmatched title records and is now a documented abstract-only decision. - Changes in activity rates in the cherry shrimp Neocaridina davidi Bouvier, 1904 (Decapoda: Caridea: Atyidae) in response to concentrations of neuropeptides and glucose (2019). Adds a direct N. davidi movement-response experiment while separating short chemical-exposure activity counts from hunger, stress, welfare and home feeding advice.
Next: The official Oxford Academic record authenticates this six-page 2019 Journal of Crustacean Biology article and exposes its abstract, but both available browser sessions report no current article access and the direct PDF endpoint returned only an access-challenge HTML page. Preserve only the abstract-reported 20-minute observations in 4-litre tanks after chemicals were applied directly to the water: MSG increased movement and became more stimulatory over time, glucose increased movement with a declining response over time, dopamine reduced movement, insulin reduced activity, insulin plus glucose showed no effect, dopamine plus glucose increased activity and dopamine plus MSG reduced activity. The abstract also says the MSG response was statistically similar to food-pellet filtrate. A related conference abstract describes groups of ten shrimp and supplies concentrations, but it is not the final article and conflicts with the article abstract wording about observations of shrimp individuals. Full text is required to verify animal source, morph and life stage, acclimation, fasting, tank number and volume, animals per tank, whether shrimp or tanks were reused, independent replication, allocation, water chemistry, treatment preparation and achieved exposure, matched vehicle controls, movement definition and coding, observer blinding, time bins, statistical model, multiplicity, raw denominators, effect sizes and uncertainty. Do not dose MSG, glucose, dopamine, insulin or haloperidol in an aquarium; call activity a direct measure of hunger, food seeking, stress or welfare; infer a feeding amount; or treat a brief pharmacological exposure as ordinary husbandry. This DOI was one of the frozen census unmatched title records and is now a documented abstract-only decision. - Effects of Thiacloprid on Freshwater Systems Dominated by Neocaridina Denticulate and Physa Fontinalis (2024). Adds a direct 28-day neonicotinoid-system lead while keeping a blocked preprint download, an unresolved taxon spelling and abstract-level NOECs out of aquarium limits.
Next: Crossref authenticates this as a 2024 SSRN preprint by Jilin Wang and Shao-nan Li, and the SSRN abstract reports one indoor-system application series at nominal 0.3, 0.9, 2.8, 8.3 and 25.0 micrograms/L thiacloprid with Neocaridina denticulate and Physa fontinalis. Preserve only the abstract-reported time-weighted-average wet-weight NOEC and LOEC of 0.72 and 2.7 micrograms/L with effects through 21 days, and antibody-corrected free-living chitobiase NOEC and LOEC of 1.79 and 5.49 micrograms/L with effects through 28 days. The abstract also reports stimulation of water fleas, chlorophyll-a and phycocyanin, suppression of selected bacterial functional groups and increased phosphate and ammonium. The 31-page SSRN manuscript download returned HTTP 403, and no separate peer-reviewed publication or lawful repository copy was located. Full text and supplements are required to verify whether the printed N. denticulate name means N. denticulata, animal source and identification, life stage, vessel and animal counts, independent replication, allocation, controls, nominal-versus-measured exposure series, dissipation and time-weighted-average calculation, water chemistry, feeding, endpoint definitions, antibody validation, statistical tests, multiplicity, raw denominators and uncertainty. Do not use a preprint abstract as a thiacloprid care threshold, infer N. davidi equivalence, interpret stimulation as benefit, or transfer results from the related tebufenpyrad and diflubenzuron systems. Crossref classifies this DOI as posted content rather than a journal article, so it does not change the frozen 198-title journal-article census. - Effects of tebufenpyrad on freshwater systems dominated by Neocaridina palmata, Physa fontinalis, and Ceratophyllum demersum (2022). Adds a direct N. palmata acaricide-system study while separating abstract-level biomass and chitobiase endpoints from mortality, home exposure and N. davidi safety.
Next: Crossref, PubMed PMID 35643160 and the official Chemosphere record authenticate this CC BY article. Its abstract reports one application in indoor systems containing Neocaridina palmata, Physa fontinalis, Ceratophyllum demersum, Simocephalus vetulus and Dolerocypris sinensis. Preserve only the abstract-reported time-weighted-average wet-weight NOEC and LOEC of 0.67 and 2.33 micrograms/L with a dose-related effect lasting 21 days, and antibody-corrected free chitobiase NOEC and LOEC of 1.41 and at most 5.64 micrograms/L. The abstract reports plant suppression, stimulation of the cladoceran and ostracod, bacterial-community changes and mixed water-chemistry responses. The publisher PDF and text-mining endpoints rejected automated retrieval, while OpenAlex reports no repository full text and Europe PMC reports no PDF or supplement. Full text and supplements are required to verify shrimp identity and stock, acclimation, animal and vessel counts, replication, allocation, exposure concentrations, analytical recovery and dissipation, time-weighted-average calculation, controls, feeding, endpoint definitions and denominators, antibody correction, statistics, multiplicity and uncertainty. Wet weight and free-living chitobiase are population-production proxies, not direct mortality, individual growth or reproduction measurements. Do not convert either NOEC into an aquarium limit, assume N. palmata equals N. davidi, or transfer the result to another pesticide. This DOI was one of the frozen census unmatched title records and is now a documented decision. - Effects of diflubenzuron on shrimp (Neocaridina palmata) in freshwater systems dominated by submerged plant (Ceratophyllum demersum) (2023). Adds a direct N. palmata insect-growth-regulator study while preventing a sensitive molting-linked proxy from becoming a tank dose or product rule.
Next: Crossref and the official open-access Chemosphere record authenticate this CC BY article. The indexed abstract reports nominal diflubenzuron treatments of 0, 0.74, 2.222, 6.667, 20 and 60 micrograms/L in 18 indoor systems divided among six groups, with three systems per group, Neocaridina palmata and Ceratophyllum demersum. Preserve only the reported highest NOEC of 0.167 and LOEC of 0.536 micrograms/L based on chitobiase activity or immunoreactive content, plus the statement that a subcellular LOEC was below 0.107 micrograms/L. Indexed full-page text says measured day-zero concentrations were 9 to 41 percent below nominal and half-lives ranged from 2.8 to 4.0 days. A 2026-08-12 retrieval audit found that ScienceDirect required human verification, the official Elsevier API returned only minimized metadata without authorized full text, Crossref confirmed the CC BY version link, and OpenAlex located no repository full text. The complete article and 3 MB supplementary document were not retrieved. Full text and supplements are required to verify shrimp stock identity, acclimation, animals per system, allocation, independence, measured concentration table, time-weighted-average derivation, controls, feeding, water chemistry, endpoint sampling and denominators, antibody validation, statistical model, comparison pairs, multiplicity and uncertainty. Chitobiase is a molting-linked production proxy, not a direct ecdysis-failure count, mortality threshold or N. davidi care target. Do not infer a safe product concentration, a household contamination trigger or equivalence with the related tebufenpyrad or thiacloprid systems. This DOI was one of the frozen census unmatched title records and is now a documented decision. - Environmental exposure and ecological risk of perfluorinated substances (PFASs) in the Shaying River Basin, China (2023). Adds a previously missing direct 28-day PFBA and PFBS mortality lead while preventing regulatory species-sensitivity values from becoming aquarium water limits.
Next: The official Chemosphere record, PubMed PMID 37478992 and EPA HERO record 11412305 authenticate a field-occurrence, eight-species toxicity and aquatic-life-criteria study. Indexed publisher tables report Neocaridina denticulata 28-day mortality NOEC values of 0.420 g/L PFBA and 0.070 g/L PFBS, species mean acute values of 7.866 and 0.713 g/L, and acute-to-chronic ratios of 18.73 and 10.19. These are chemical-specific test results, not measurements of ordinary aquarium exposure. The complete article and supplement remain required to verify shrimp source and identity, size and life stage, acclimation, vessel number and volume, animals per vessel, independent replication, allocation, controls, PFAS salt and purity, concentration series, renewal, analytical verification, water chemistry, feeding, mortality checks and definition, censoring, NOEC test and multiplicity, raw denominators, uncertainty and whether each species test was newly run or imported. ScienceDirect presents human verification and no lawful repository manuscript was located in this access pass. Do not convert the NOECs, species mean acute values, acute-to-chronic ratios, predicted no-effect concentrations or aquatic-life criteria into an N. davidi home threshold, product-safety claim, treatment trigger or permission to expose animals. This title does not contain Neocaridina and therefore expands the priority queue without changing the frozen 198-title DOI census. - Toxic Effects of Ammonia on the Freshwater Shrimp Neocaridina denticulata (2007). Identifies the strongest located chronic ammonia lead while preventing an abstract-level maximum acceptable concentration from becoming an aquarium target or intervention threshold.
Next: The official National Taiwan University record identifies a 79-page 2007 Fisheries Science MSc thesis, but its 623.1 KB PDF is restricted and requires authorization. Preserve only what the detailed Chinese abstract reports: acute 24-, 48-, 72- and 96-hour total-ammonia LC50 values of 109.84, 76.60, 53.15 and 37.82 mg N/L for 4.42 +/- 0.28 mm shrimp and 332.95, 266.12, 207.97 and 171.97 mg N/L for 9.22 +/- 0.41 mm shrimp; chronic nominal total-ammonia groups of 0, 0.38, 1.14 and 3.80 mg N/L; poorer growth above 1.14 mg N/L; lower female ovigerous rate, hatchling count and male appendix-masculina index above 1.14 mg N/L; no ovigerous females plus altered feeding and oxygen consumption at 3.80 mg N/L; and an abstract-labeled maximum acceptable concentration of 0.38 to 1.14 mg N/L total ammonia-N and 0.0013 to 0.0038 mg N/L NH3. Full text is required to verify stock identity, taxonomic determination, vessel number and volume, replication, animals per vessel, chronic duration, schedules and endpoint denominators, water pH, temperature and hardness, ammonia preparation and renewal, analytical verification and decay, unionized-ammonia calculation inputs, feed and intake, allocation, mortality and censoring, exact tests, uncertainty and how the maximum acceptable concentration was derived. Do not use the abstract range as a care threshold, assume N. denticulata is interchangeable with aquarium N. davidi, or treat the reported acute values as chronic limits. This non-DOI source expands the priority queue but does not change the frozen 198-title DOI census. - Postembryonic development and differentiation of the midgut in the freshwater shrimp Neocaridina davidi (Crustacea, Malacostraca, Decapoda) larvae (2021). Could improve the anatomy and early-development map, but the abstract and public peer-review history cannot resolve the final staging definitions, microscopy units, denominators or statistical analysis needed for care guidance.
Next: Keep full text needed after checking the official publisher record, PubMed PMID 33074574, institutional pages, scholarly indexes and all six public peer-review artifacts. The reviews authenticate a detailed ultrastructural study comparing zoea I and zoea III with microtomography, light microscopy, transmission electron microscopy, histochemistry, phosphohistone H3 labeling and a TUNEL apoptosis assay. The author response says zoea I were non-feeding and lecithotrophic while zoea III were feeding, but it does not expose the final spawning and hatching definitions, specimen counts, allocation across methods, independent microscopy units, field selection, TUNEL controls, denominators, comparison pairs or statistical results. Reviewers required correction of a duplicated image, R-cell versus E-cell terminology, cell labels, table headlines, histochemical interpretation and apoptosis-versus-necrosis wording. The response also says endocrine-cell identity could not be established because peptide-appropriate histochemistry was not performed. These revisions improve the audit trail but do not substitute for the final 18-page article, supplements or data. Do not use the abstract or reviews to overturn direct-development descriptions, define a home feeding stage, diagnose midgut health, infer probiotic effects, predict molt timing or establish maturity. Retrieve and audit the complete article, supplements and underlying image or measurement data through lawful library access or a corresponding-author request. - De novo assembly transcriptome analysis reveals the genes associated with body color formation in the freshwater ornamental shrimps Neocaridina denticulate sinensis (2022). Adds a public nine-library red, blue and chocolate cephalothorax transcriptome while separating expression associations and mined SSRs from inherited colour genes, named trade lines and breeding forecasts.
Next: Complete methods and supplements are still required through a library or author request. PubMed and official Elsevier metadata authenticate the closed article. The publisher abstract and preview report 1.5 to 2 cm adults from one Xiamen supplier; red, blue and chocolate phenotypes selected from forward-cross and backcross progeny and then bred within phenotype for five generations; nine cephalothorax cDNA libraries, three per phenotype; Illumina HiSeq 4000 sequencing; 75,022 assembled unigenes; 829, 554 and 3,194 differentially expressed unigenes in the three pairwise comparisons; and 6,328 mined SSRs. Official ENA project PRJNA382065 independently confirms nine PolyA paired-end runs, sample aliases RD_1 to RD_3, BL_1 to BL_3 and CH_1 to CH_3, adult cephalothorax metadata, a 2018-12-25 collection date and Xiamen location. The archive does not state the shrimp count or pooling behind each library, sex, family and parental contribution, tank allocation or independence, and the accessible article preview does not expose the complete culture conditions, phenotype measurement, RNA sampling, differential-expression thresholds, multiplicity handling, qPCR validation units or supplements. Nine libraries are not automatically nine animals or nine independent tanks. The phenotype labels are not evidence for Blue Dream, Bloody Mary, Sunkist, Chocolate or another named seller line. Pairwise expression differences in mixed cephalothorax tissue do not establish causal DNA variants, dominance, segregation, inheritance, a cross outcome or a breeding target. The 6,328 SSR sequences are mined candidates, not validated polymorphic markers or consumer line tests. Retrieve the complete article and supplements before evidence intake, establish the experimental and family units, and determine whether PRJNA382065 contains any reused 2018 skin libraries outside the nine-study subset before combining datasets. - Arsenic metabolism in a freshwater food chain: Blue-green alga (Nostoc sp.) to shrimp (Neocaridina denticulata) to carp (Cyprinus carpio) (1993). Could add a second direct Neocaridina arsenate experiment while separating waterborne survival and accumulation from dietary transfer, methylation, nitrogen effects and aquarium safety.
Next: Complete methods are required through a library or author request. Crossref publisher metadata and abstract plus the EPA HERO record authenticate a Nostoc to Neocaridina denticulata to carp sequence, survival below reported 1000, 2 and 60 mg As(V) per cubic decimetre for the three organisms, a nitrogen-associated change in Nostoc accumulation, waterborne arsenate accumulation and partial methylation, carp gut distribution, and lower total accumulation with a higher methylated fraction across dietary trophic steps. The accessible abstract distinguishes route-dependent arsenic profiles: monomethylarsenic predominated in carp gut after aqueous accumulation, while food-chain transfer produced no or only trace monomethylarsenic in the three organisms. It does not expose survival duration or definition, animal count, organism source and identity, size or sex, acclimation, vessels, replication, allocation, controls, nitrogen levels, water chemistry, renewal, measured exposure, mortality schedule, tissue and whole-body allocation, feeding duration, food biomass, consumed ration, depuration, extraction, arsenic-speciation recovery, statistics or uncertainty. This is a distinct paper from the 1992 and 1994 food-chain publications but shares authors and program logic, so it is not independent laboratory replication. Do not treat survived below 2 mg/L As(V) as a safe or chronic limit, combine aqueous and dietary routes, equate methylation with detoxification, infer universal biodilution, recommend Nostoc or contaminated biomass as food, or claim that nitrogen addition controls aquarium arsenic. Retrieve all ten pages and any supplement before evidence intake. - Biomethylation and biotransformation of arsenic in a freshwater food chain: Green alga (Chlorella vulgaris) to shrimp (Neocaridina denticulata) to killifish (Oryzias latipes) (1994). Could add direct arsenic-species tolerance, aqueous accumulation, depuration and experimental food-chain evidence while separating LC50, biotransformation and biodilution from aquarium safety claims.
Next: Complete methods are required through a library or author request. Crossref publisher metadata and abstract plus the EPA HERO record authenticate naturally collected Neocaridina denticulata, disodium arsenate, methylarsonic acid, dimethylarsinic acid and arsenobetaine comparisons, abstract LC50 values of 1.5, 10, 40 and 150 micrograms As per millilitre, selected aqueous accumulation exposures, transfer to arsenic-free medium, excretion and a Chlorella to shrimp to killifish food-chain sequence. The accessible records do not expose LC50 duration, animal count, source locality, taxon verification, size or sex, acclimation, water chemistry, vessel, replication, allocation, renewal, analytical concentration verification, mortality schedule, concentration-response model, arsenic extraction and speciation recovery, feeding duration, food biomass, consumed ration, depuration duration, excrement collection, controls, statistical units or uncertainty. Do not convert LC50 mortality medians into safe concentrations, treat total arsenic as interchangeable with chemical species, assume methylation means detoxification, infer universal biomagnification or biodilution, use the food-chain result as a feeding recommendation, or claim that transfer to clean water guarantees complete recovery. Retrieve all nine pages and any supplement before evidence intake. - Freshwater shrimp (Neocaridina denticulata) as a nature-based restoration tool for macrophyte recovery and improved water quality in eutrophic ponds (2025). Could test filamentous-algae consumption, macrophyte recovery and water-quality outcomes across feeding trials, microcosms and field evaluation while defining the boundary against aquarium cleanup and animal introduction.
Next: Full methods still needed. The official publisher abstract reports feeding trials, controlled microcosms, long-term field evaluation, reduced filamentous algae, improved clarity, an 11-fold macrophyte-abundance result and a self-sustaining shrimp population. The publisher page and official metadata do not expose animal and vessel counts, treatment allocation, controls, shrimp density, endpoint definitions, intervention timing, field comparators, replication, analysis units or the numerical water-quality results here. OpenAlex reports no repository full text or PDF. Do not convert the abstract into a home algae list, stocking rate, water-quality promise or instruction to introduce or release shrimp. Retrieve the article and supplements through the publisher, a library or the corresponding author. - Identification of a new ABCB6 gene correlated with economic trait for pigmentation of cherry shrimp (Neocaridina denticulata) (2026). Could add another functional pigment-transport candidate while testing whether an economic-trait title is being overextended into commercial-line genetics.
Next: Full methods still needed. The publisher abstract reports red, yellow, blue and wild laboratory strains, expression profiling, in situ hybridization and RNA interference, but accessible records do not expose animal and maternal units, strain and tank replication, controls, allocation, phenotype scoring, analysis units or full statistical methods. Do not convert the abstract into a named-line marker, inheritance model, colour-food claim or breeding test. Retrieve the article and supplements through a library or corresponding-author request. - Crustacyanins as regulators of functional complementation, cuticle development, lipid metabolism, pigmentation, and immunity in shrimp (2026). Could clarify functional overlap among 24 crustacyanin-family genes while preventing multi-omics pathway labels from becoming named-line genetics, colour recipes, molting advice or disease-resistance claims.
Next: Full methods still needed. The official publisher preview reports 24 NdCRCN genes, separate RNA-interference targeting of the highest-expressed A and C subunits, transcriptomic and proteomic comparisons, compensatory expression among family members, and anti-NdCRCN co-immunoprecipitation followed by LC-MS/MS. Accessible records do not expose shrimp and vessel counts, stock identity, sex or molt state, dsRNA and injection controls, allocation, knockdown denominators, library pooling, phenotype measurements, co-immunoprecipitation controls, endpoint-specific replication or full statistical methods. The preview reports pathway and interacting-protein results, not named trade-line crosses, standardized visible-colour change, carotenoid chemistry, whole-animal molt outcomes, bacterial challenge, survival or disease protection. A retained crustacyanin PDF was verified page by page as the distinct 2025 BMC Genomics article at DOI 10.1186/s12864-025-12371-6 and cannot satisfy this 2026 Aquaculture lead. Do not convert gene-family membership, pathway enrichment, compensatory expression or protein interaction into a breeding marker, colour-food recipe, molt intervention, immune supplement or disease-resistance claim. Retrieve the article and supplements through a library or corresponding-author request. - Mechanistic insights into novel triclosan target pathways in Neocaridina denticulata revealed by multi-omics integration (2026). Could add a direct acute household-antimicrobial exposure with measured body accumulation, molecular pathways and biochemical validation.
Next: Full methods still needed. PubMed, Crossref and the publisher abstract report 24-hour nominal exposures of 1, 5 and 10 micrograms per litre with whole-body multi-omics and biochemical endpoints, but the accessible material does not expose animal and vessel counts, replication, allocation, solvent control, measured water concentrations, omics pooling, endpoint-specific denominators or analysis units. Do not convert the abstract into an aquarium threshold, product warning, clinical sign or decontamination protocol. Retrieve the article and supplements through a library or corresponding-author request. - Research on the Response of Neocaridina denticulate to the Toxicity of Cu2+ and Chlorpyrifos (2014). Identifies the acute mortality and mixture experiment that supplied the 96-hour LC50 values inherited by the 2015 copper and chlorpyrifos biomarker paper.
Next: The exact eight-page journal PDF and source identity are located. Its extracted text exposes a 96-hour semi-static design, three parallel beakers per nominal concentration, blank and chlorpyrifos vehicle controls, probit LC50 analysis and a copper-ion plus chlorpyrifos mixture analysis, but the embedded font drops the decisive concentration, interval and additive-index table cells. Direct rendered-page inspection is still required before intake. A 2026-08-12 retrieval audit found that the official PDF returned HTTP 418 to a direct request and an access-blocked page in a normal browser; a focused exact-title search found citations but no accessible primary copy. Keep this lead outside evidence. Do not promote the 3.44 mg/L copper-ion or 0.06 micrograms/L chlorpyrifos values repeated by the 2015 companion paper, the later 0.4 micrograms/L 24-hour chlorpyrifos citation, the reported synergy classification or the unquantified molting observation into primary table evidence, an N. davidi threshold, a safe aquarium level or a mixture prediction. - Transcriptome analysis of Neocaridina denticulate sinensis under copper exposure (2021). Could add a cephalothorax RNA-seq copper experiment and clarify whether immune and molting pathway interpretations reproduce across tissues and better-defined biological units.
Next: Full methods still needed. The official publisher preview reports 20 adult shrimp per control or nominal 2.5 micromoles per litre copper-ion group for 48 hours, one described tank per group, three separately dissected cephalothorax samples per group, six RNA-seq libraries, 122,512 assembled unigenes, 219 differentially expressed genes and seven qPCR checks. The accessible material does not expose complete tank replication, water chemistry, copper verification, sample-to-animal mapping, RNA-seq contrasts, qPCR denominators, reference genes or full statistical methods. Do not convert abstract pathway enrichment or transcript direction into molting impairment, immune competence, whole-animal toxicity, a biomarker panel, diagnosis or safe aquarium concentration. Retrieve the full article and supplements through a library or corresponding-author request. - Transcriptomic analysis of Neocaridina denticulate sinensis hepatopancreas indicates immune changes after copper exposure (2022). Could add a 12-hour hepatopancreas RNA-seq comparison to the same laboratory group's 48-hour cephalothorax study while testing whether tissue and time differences are being mistaken for independent replication.
Next: Full methods still needed. The official publisher preview reports laboratory-bred adults, 20 shrimp randomly selected per 0 or nominal 2.5 micromoles per litre copper-ion group, analytical-grade copper sulfate pentahydrate, a 12-hour endpoint, six hepatopancreas RNA-seq libraries, 23,266 assembled unigenes, 16,423 differentially expressed genes and eight qPCR checks. The accessible material does not expose the completed copper-preparation sentence, treatment-vessel count and volume, water chemistry, analytical copper verification, sample-to-animal and sample-to-tank mapping, library pooling, qPCR denominators and reference genes, full differential-expression thresholds, multiplicity handling or whether this cohort was independent of the same group's 2021 cephalothorax paper. ResearchGate offers an author-request page rather than full text. Do not convert abstract immune-pathway enrichment or transcript direction into immune competence, detoxification, copper tolerance, toxicity, disease resistance, a diagnosis, safe concentration or independent replication. Retrieve the article and supplements through a library or corresponding-author request. - Membrane-bound trehalase enhances cadmium tolerance by regulating cell apoptosis in Neocaridina denticulata sinensis (2024). Tests a cadmium-responsive trehalase candidate while exposing the crucial difference between shrimp molecular responses and metal tolerance measured in recombinant bacteria.
Next: Full methods still needed. PubMed, the publisher abstract and the Hebei University laboratory summary report NdTre2 cloning, gill-biased expression that decreased 12 hours after cadmium stimulation, double-stranded-RNA knockdown, gill transcriptomics, selected apoptosis-pathway validation, DNA fragmentation and TUNEL/DAPI staining. The reported cadmium-tolerance assay overexpressed recombinant NdTre2 in Escherichia coli and measured bacterial survival and growth, not shrimp survival or recovery. Accessible sources do not expose shrimp and vessel counts, cadmium concentrations and preparation, water chemistry, measured water or tissue cadmium, exposure and injection controls, allocation, RNA-seq pooling, endpoint denominators, blinding, complete statistical methods or whole-animal shrimp outcomes after knockdown. ResearchGate offers an author-request page rather than full text. Do not convert the title, pathway enrichment, gill apoptosis staining, recombinant-protein binding or bacterial assay into demonstrated shrimp cadmium tolerance, immune competence, molting control, a safe concentration, diagnosis, treatment, supplement or genetic test. Retrieve the article and supplements through a library or corresponding-author request. - Identification and functional analysis of a novel L-type lectin (NdLTL1) from Neocaridina denticulata sinensis (2025). Separates shrimp challenge-responsive expression from recombinant-protein binding and bacterial agglutination while preventing an in vitro assay from becoming disease-resistance or supplement advice.
Next: Full methods still needed. PubMed, the publisher preview and the Hebei University laboratory summary report a market source, one-week acclimation at 25 C, genome-wide mining of 179 lectin-like sequences, high cardiac NdLTL1 expression, increased gill expression after Vibrio parahaemolyticus exposure, recombinant NdLTL1 produced in Escherichia coli, binding to several bacteria and carbohydrates, calcium-dependent bacterial agglutination and in vitro bacterial-growth assays. Accessible sources do not expose challenge animal and vessel counts, independent tank replication, bacterial dose and route, controls, allocation, tissue pooling, sampling denominators, recombinant-protein and assay controls, complete replication or full statistical methods. No accessible record reports shrimp survival, disease signs, bacterial load, clearance or protection after manipulating NdLTL1. ResearchGate states that no full text is available and offers a request page. Do not convert challenge-responsive expression, binding, bacterial clumping, calcium dependence or in vitro bacterial growth into demonstrated shrimp immune competence, disease resistance, a diagnosis, treatment, probiotic, prebiotic, sugar product or calcium supplement. Retrieve the article and supplements through a library or corresponding-author request. - RNA-seq analysis revealing the immune response of Neocaridina denticulata sinensis gill to Vibrio parahaemolyticus infection (2022). Adds the direct gill transcript experiment cited by the later NdLTL1 paper while separating PBS-versus-bacterial stimulation from infection severity, disease protection and treatment evidence.
Next: Full methods still needed. PubMed and the publisher preview report market-source animals 1.5 plus or minus 0.2 cm long, one month in a 25 C laboratory circulating-water system, a PBS control and Vibrio parahaemolyticus stimulation comparison, six gill RNA-seq libraries labelled C12_1 through C12_3 and S12_1 through S12_3, 1,358 differentially expressed genes and qPCR checks of six selected lysosome-pathway genes. Accessible material does not expose the complete bacterial preparation, challenge dose and route, animal and vessel counts, independent tank replication, allocation, whether gill libraries pooled animals, sample-to-animal and sample-to-tank mapping, qPCR denominators and reference genes, tissue-damage methods, complete statistical thresholds or multiplicity handling. No accessible record reports shrimp survival, clinical signs, bacterial load, clearance, transmission or protection. Do not convert transcript direction or pathway enrichment into natural-infection risk, disease diagnosis, pathogenicity, immune competence, disease resistance, treatment, prevention or a validated biomarker panel. Retrieve the article and supplements through a library or corresponding-author request, then compare its animals and challenge protocol with the same laboratory group's later NdLTL1 paper rather than assuming an independent replication. - Transcriptome analysis of Neocaridina denticulate sinensis challenged by Vibrio parahemolyticus (2022). Adds a hepatopancreas transcript comparison while separating an injected challenge discussed in an AHPND context from evidence that the tested strain carried PirAB toxins or caused AHPND or whole-animal disease in Neocaridina.
Next: Full methods still needed. PubMed and the publisher preview report open-fair animals maintained in the laboratory for two years, 30 healthy shrimp approximately 1.5 plus or minus 0.5 cm long, 25 plus or minus 1 C circulating water, hepatopancreas sampling after Vibrio parahaemolyticus injection, six cDNA libraries, 23,624 genes, 21,464 differentially expressed genes and eight qPCR checks. The accessible preview cuts before the complete acclimation and bacterial-challenge methods and does not expose group allocation, bacterial dose and volume, strain characterization, injection and control details, animal and vessel counts per treatment, independent tank replication, library pooling, sample-to-animal and sample-to-tank mapping, qPCR denominators and reference genes, complete differential-expression thresholds or multiplicity handling. It reports no shrimp survival, clinical signs, bacterial load, clearance, transmission or hepatopancreas pathology. The title, abstract and keywords discuss AHPND, but the accessible record does not establish that the challenge strain carried PirAB toxins or caused AHPND in Neocaridina. Six libraries are not automatically six animals or tanks, and 21,464 changed transcripts are not 21,464 disease mechanisms. Do not infer natural aquarium infection risk, an AHPND diagnosis, pathogenicity, immune competence, disease resistance, treatment, prevention or a validated biomarker panel. Retrieve the article and supplements through a library or corresponding-author request, then establish whether this was a distinct animal cohort and challenge protocol from the same laboratory group's 2022 gill RNA-seq paper rather than calling the two independent replication. - Differential immune responses of the green neon shrimp (Neocaridina denticulate) to dipropyl phthalate (2011). Could connect DPrP exposure to time-specific immune assays and bacterial-challenge mortality without inferring disease resistance from transcript levels alone.
Next: Full methods still needed. PubMed and the publisher abstract report nominal 0, 1, 5, 10 and 50 mg/L DPrP exposures, six immune parameters, Aeromonas veronii challenge and mortality on days 1, 3, 5 and 10, but the article is paywalled and the indexed request page exposes no complete methods. Animal and vessel counts, treatment replication, acetone control, exposure renewal, bacterial dose and route, challenge allocation, endpoint denominators, censoring and analysis units remain unverified. Do not convert abstract mortality percentages into an aquarium threshold, plastic-product warning, infection diagnosis, immune supplement claim or treatment protocol. Retrieve the article through a library or corresponding-author request. - Effect of different substrates on growth and biochemical composition of the ornamental red cherry shrimp Neocaridina davidi (2022). Could separate substrate effects on growth from colour preference and general habitat assumptions.
Next: Full methods still needed. The 90-day abstract compares Vesicularia, Ceratophyllum, Cabomba and plastic net and reports growth, survival and ovigerous-female outcomes. The official 710291-byte CONICET published-version deposit is restricted, Wiley exposes only the abstract without access, and scholarly indexes locate no open copy. Aquarium replication, allocation, conditioning, surface area, feeding and analysis units remain unverified, so the percentages do not support a habitat recommendation. Request the article or study data from the corresponding author. - Characterization of the moult cycle in Neocaridina denticulata sinensis Kemp, 1918: the moulting frequency, moulting stages, and haemolymph ecdysteroid levels (2022). Could replace generic molt-frequency calendars with life-stage, temperature and visible-stage observations from a direct Neocaridina study.
Next: Full methods still needed. The abstract reports 14 molts from hatch through first complete pleopod development at 25 C, four main periods, five premolt substages and adult male-versus-female ecdysteroid patterns. The publisher article is paywalled and no legal public manuscript was located. Animal counts, observation intervals, rearing units, independence, censoring and the exact definition of first complete pleopod development remain unverified, so the abstract does not support a home molt calendar or intervention. Request the article or study data through a library or corresponding author. - Leaf-litter preferences of the introduced freshwater shrimps Atyaephyra desmarestii and Neocaridina davidi (2017). Could replace generic botanical claims with a bounded comparison of conditioned leaf species, life stages and consumption.
Next: Full methods still needed. The official University of Cologne record and OAI metadata identify the accessible 174 kB file as a four-page Thesis Abstract. The German National Library catalogs a physical 63-page 2018 dissertation, and its official contents page places the leaf-litter article in chapter III on pages 34 to 50. It supplies no electronic dissertation file. OpenAlex reports no repository with full text, and its apparent University of Cologne OAI identifier 24511 is stale because the repository returns idDoesNotExist. The publisher reader stops at human verification and its machine-readable article route denies access. The abstracts report adult versus juvenile preferences, nighttime activity and a 51.0 percent leaf-litter dry-weight result normalized to body dry weight, but choice-vessel replication, conditioning duration and water, leaf mass or area normalization, position rotation, other feeding, decomposition and biofilm controls, non-consumption mass-loss correction, observation schedule, body dry-weight estimation, experimental unit and analysis remain unverified. These abstract findings do not support a leaf recommendation, aquarium ration, replacement interval, complete-diet claim or health claim. Request the 16-page article, physical dissertation or study data through a library, repository or corresponding author.
