Open the source

This record is a claim boundary, not a quality badge. Evidence class and species relationship describe what was studied. They do not make the result universal, complete or automatically applicable to a home aquarium.

Source taxon as published
Market-labeled Neocaridina denticulata and Neocaridina palmata; no host-identification method reported
Environment
Two hundred shrimp sampled across more than eight aquariums operated by the only ornamental-shrimp seller at one fish market in Purbalingga, Central Java, Indonesia
Life stages
market shrimp reported as male or female; sexing method and life stage were not described

What was studied

Study shape: One hundred market-labeled N. denticulata and 100 market-labeled N. palmata were transported in market aquarium water. Gill and cephalothorax material was scraped onto slides and examined by microscopy for organisms reported as sessile bdelloid rotifers, Vorticella sp. and Zoothamnium sp.

Experimental unit: Individual examined shrimp, clustered within an unreported number of sampled aquariums from one seller and one claimed river source

Endpoints: presence of reported organism group, host label, reported sex, gill or cephalothorax location.

Claim boundary

What it can support: In this one-seller sample, the authors reported at least one of the three organism groups on 156 of 200 examined shrimp, including 78 of 100 under each market species label.

What it cannot support: Aquarium identities and sample counts, collection dates, host-species identification, sexing method, microscope magnification, diagnostic key, stain, image vouchers, molecular confirmation, examiner blinding, confidence intervals and the named statistical test were not reported. The two market labels were reportedly kept together, and the analysis did not account for aquarium clustering. No tissue damage, respiration, behaviour, growth, reproduction, mortality, transmission, treatment or causal disease endpoint was measured. The 78 percent result is not a trade-wide prevalence estimate, does not validate a home diagnosis, does not prove every detected organism was parasitic or harmful and does not establish a treatment indication.

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.

Correction impact

If this source boundary changes, these are the known downstream consumers. The list distinguishes scientific re-review from generated parity and historical follow-up.

Editorial review required (8)

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 (19)

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 (1)

Do not silently rewrite history. Decide whether the prior change record remains accurate and publish a new correction or scope note when needed.

How this record is classified

Morphology or taxonomy: Anatomy, specimen identification or taxonomic relationships were studied with stated methods. A trade name or photograph cannot replace those methods.

Direct Neocaridina evidence: The source measured animals named within Neocaridina. Direct still does not mean universal or sufficient.

Topics: Health, Anatomy, Species and taxonomy

Critically appraise this source without a score

These questions fit this record's morphology or taxonomy role. They are prompts, not automatic judgments. Open the original source to answer them.

  1. Identity and provenance: How were the organism, population, stock and life stage identified and sourced? A published name or seller label can hide a taxonomic, population or life-stage transfer.
  2. Independent unit: What unit was independently assigned or sampled, and how many units support each comparison? Animal counts do not create independent replication when animals share a vessel, site, family or treatment history.
  3. Comparison and context: What was the actual comparator, allocation process, environment, duration and material condition? A result has meaning only against the comparison and conditions that produced it.
  4. Endpoint and measurement: Which endpoint was measured, with what method, unit, timing, resolution and decision rule? One endpoint cannot silently become survival, welfare, diagnosis, reproduction or long-term population performance.
  5. Denominators and missingness: Are starting counts, exclusions, losses, missing observations and analysis denominators reconciled? Unreported or changing denominators can alter the apparent direction, precision and applicability of a result.
  6. Transfer boundary: What is the nearest tempting aquarium claim that this source design cannot establish? Direct evidence can still be narrow, and adjacent evidence can be useful only while the inference remains visible.
  7. Examined material: Which specimens, localities, sexes, stages, types or sequence accessions were actually examined? A diagnosis applies to examined material and methods, not automatically to a trade-line photograph.
  8. Diagnostic characters: Which characters or loci distinguish the taxon, and were alternatives explicitly compared? Color alone may be variable, convergent or unrelated to the diagnostic character.
  9. Name history: Were synonyms, historical combinations, type material and later revisions checked? An older title can describe a population that later work placed in another taxon.
  10. Consumer identification limit: Can the required character or method be observed reliably in an ordinary live-animal image? A valid taxonomic method may still be unavailable to a keeper examining one photograph.
