Breeding and life cycle of the ornamental freshwater shrimp Neocaridina davidi in a biofilm-based culture system
Viau et al., 2020. Aquaculture Research 51: 3847-3864.
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

What was studied
Study shape: The full life cycle and juvenile outcomes were followed while comparing conditioned artificial substrates.
Experimental unit: Substrate treatment culture unit
Endpoints: juvenile survival, growth, biomass, biochemical reserves, reproduction.
Claim boundary
What it can support: The tested biofilm community supported the life cycle and substrate treatment changed juvenile outcomes.
What it cannot support: It does not establish that any home-aquarium film is complete food or that tank age measures grazing value.
Publication status audit
Matched in dated Crossref query
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 (15)
This curated wording or synthesis must be reconsidered when the source boundary changes. A passing generator test cannot decide the new scientific meaning.

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.
- Which direct leaf-litter studies separate preference, consumption, decomposition, water effects and long-term shrimp outcomes? Dated literature search
The dated search used this exact source as a candidate (included: Breeding and life cycle of the ornamental freshwater shrimp Neocaridina davidi in a biofilm-based culture system). Preserve the search history and decide whether a revised or additional search is required.
How this record is classified
Controlled experiment: An assigned treatment or controlled comparison. The treatment, unit, duration and endpoint still limit the claim.
Direct Neocaridina evidence: The source measured animals named within Neocaridina. Direct still does not mean universal or sufficient.
Topics: Feeding, Habitat, Breeding, Growth and lifespan
Critically appraise this source without a score
These questions fit this record's controlled experiment role. They are prompts, not automatic judgments. Open the original source to answer them.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Treatment assignment: Were independent units assigned to treatments, and were baseline conditions comparable? Unclear allocation or baseline imbalance can confound the treatment comparison.
- Replication: Were treatment vessels or other exposure units independently replicated rather than subsampled? Repeated animals or assays inside one exposure unit do not replicate the environmental treatment.
- Exposure verification: Was the treatment, dose, feed intake or environmental exposure measured and maintained as described? Nominal treatment labels may not equal the exposure animals actually received.
- Analysis: Did the statistical model match the unit, repeated measures, multiplicity and missing outcomes? A precise p-value cannot repair a mismatched unit or unaccounted comparison structure.
