Relative tag mass informs planning but cannot guarantee tolerance. A 2026 meta-analysis supports assessing burden alongside species, device characteristics and study duration.
A tank mix-up can break the connection between line, specimen and result. Link parents, clutches and movements to preserve genetic identity without mistaking diversity for error.
An internal transfer changes the receiving exhibit’s conditions, interactions and load. Compare environments, preserve the health record and arrange a fallback before moving fish.
An IPNV detection does not by itself explain salmonid mortality. Stock history, tissue findings and virology need to support a specific health management decision.
A study in Catalan chub links mucus cortisol with blood cortisol and habitat quality. Because fish were captured and confined before sampling, the measurements cannot directly describe the undisturbed state of fish living freely in the river.
A tightly standardised experiment may still be difficult to reproduce elsewhere. A simulation study using rodent-model data clarifies this problem and offers a cautious starting point for planning more representative studies with fish.
A productivity–susceptibility analysis ranks 306 marine fish species in the aquarium trade. Public aquariums can use it to prioritise sourcing checks, while recognising that a species score does not certify a particular shipment or local fishery.
A Norwegian field trial links an additional vaccine against variant Moritella viscosa to lower mortality during winter ulcer outbreaks. Cage-level comparisons, local reactions and commercial production constraints are central to interpreting the findings.
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.
