A three-generation zebrafish experiment reported different responses for survival, growth and reproduction. Environmental interpretation must retain the chemical, measured concentrations, life stages and endpoints actually tested.
Death counts alone cannot compare aquatic research facilities. Population, time window, life stage and welfare-related euthanasia must be explicit before the record can support a health decision.
In public aquariums, a longer feeding opportunity is useful only if fish obtain enough food without excessive competition or accumulating leftovers. Assess access, behaviour and water conditions together.
A 2024 European sea bass study separates inflammation from disease after exposure to Tenacibaculum maritimum. Its value for marine farms lies in understanding what an experimental challenge actually tests.
Laboratory studies show that antidepressants can alter endocrine functions in fish. Interpreting a river signal requires the compound, concentration and exposed life stage to remain attached to the result, alongside the limits of field extrapolation.
Observing trout from the bank avoids capture but does not automatically produce reliable welfare data. France’s AQUA BIEN-ÊTRE project combines health and behavioural indicators while identifying the need for further repeatability work.
A US aquarium and university network is sharing marine fish breeding methods and reports distributing juveniles. Reliable supply for collections also requires health records, cohort traceability and evidence that successes can be repeated.
A year-long facility study found no significant survival or breeding benefit from artificial plants in zebrafish tanks. Fish occupied the planted area less often, highlighting the need to assess usable swimming space alongside enrichment.
Three common guitarfish died rapidly in an Italian aquarium. Examination identified Photobacterium damselae subsp. damselae. The report supports a coordinated investigation, while leaving the infection source and effective treatment unresolved.
Reopening a river corridor can benefit native species while creating a route for invasive species. A scientific synthesis supports assessing that trade-off before barrier removal and carrying it into long-term monitoring.
A review of 192 studies identifies many approaches to bacterial disease control in tilapia. Most concern prevention; direct antibiotic comparisons and evidence from working farms remain limited.
A dataset captures swimming and interactions between adult zebrafish pairs in three dimensions. It supports behavioural analysis, but does not establish a validated health alarm or automated humane-endpoint detector.
