Coral quarantine is more than a dip or a fixed number of days. It combines separated flows, repeated observation, stable water quality and a documented release decision.
Across 91 Flemish lowland river sites, eDNA produced ecological quality classes comparable to a conventional fish index. The result supports a hybrid approach, not immediate regulatory substitution.
Testing a few fish on fixed dates does not describe a facility’s health status. FELASA–AALAS recommendations connect daily surveillance, sampling, diagnosis and reporting to actual research risk.
Adding structures to a tank does not automatically improve welfare. Rainbow trout trials report behavioural and production benefits, but farms must protect water flow, cleaning and biosecurity.
This small freshwater cnidarian combines budding, regeneration, stem-cell lineages and whole-body imaging in a model that is simple in shape but not in biology.
Historic slag deposits on Marseille’s southern coast contain lead and arsenic. Assessing risk to fish requires tracking transfer pathways through to biological effects.
Preparing a ration does not prove that every fish ate. Useful monitoring connects preparation, individual access, refusals, body condition and effects on the exhibit.
A longer pathogen list is not automatically a stronger health plan. Risk-based surveillance connects hazards, transmission routes, consequences and each farm’s capacity to act.
A thread that performs well in one species or water body is not a universal choice: sutures belong within the complete surgical and monitoring protocol.
The speed of a larval mortality event should not force an early choice between water, nutrition and infection: the entire hatchery is the unit of investigation.
The remarkable regenerative capacity of Schmidtea mediterranea makes it a powerful model, provided that strain, water, temperature, feeding and fasting are documented.
