Zebrafish enrichment is an environmental variable to test: behavioural benefit, hygiene, stocking density and reproducibility must be assessed together.
Fish parasites can strengthen pollution monitoring when host ecology, parasite life cycles, chemical matrices and seasonal variation are analysed together.
Reliable shark and ray diets combine suitable prey, individual delivery and longitudinal records rather than relying on one universal feeding percentage.
Interpret aquaculture ammonia tests with the right units, pH, temperature and system history to plan an appropriate response and monitor fish after an incident.
A fibre found in a fish is not necessarily plastic: sampling, contamination blanks and chemical identification determine what monitoring results can establish.
In turquoise killifish research, record cohort history, diet, water conditions and behaviour to distinguish experimental findings from changes in husbandry.
Nets, buckets and hoses can connect aquarium tanks: organise cleaning, disinfection and release for reuse to strengthen the daily equipment biosecurity process.
Road salt can affect freshwater long after snowmelt. Combine conductivity, chloride analysis and catchment records to assess exposure and protect aquatic life.
Farmed salmon respond to heat, feeding and maintenance together. Combine environmental records and fish observations to guide proportionate farm decisions.
Low thyroid results in sharks and rays require careful interpretation. Review assay performance, clinical imaging and feeding records before changing care.
