True and spiny lobsters need shelter, controlled lighting and usable space. A new review helps aquarium teams reassess housing and welfare checks in practice.
In shrimp RAS, stocking density affects survival, growth, appendages and behaviour. A new study identifies signals to track without setting a universal limit.
Zebrafishology turns reproducibility into a practical reporting checklist covering fish, husbandry, replicates, randomisation, analysis and data access.
For sea-caged European seabass, useful welfare monitoring combines mortality, health, behaviour and water quality without mistaking consensus for validation.
In larval zebrafish, oligodendrocytes use a protein best known from inhibitory synapses to influence axon-class targeting and restrain myelin sheath length.
A review documents rising sand tiger shark collections in Delaware Bay and calls for population assessment, lifelong traceability and demonstrable conservation returns for every permit.
Across 38 French and Belgian fishponds, higher fish densities were associated with lower macrophyte richness, informing production–biodiversity trade-offs.
Acoustic tracking of 80 silver eels in the Loire basin found little predation, but all four sensor activations followed passage of the Châtellerault dam.
Atlantic salmon fry given equal total EPA and DHA in three different proportions showed distinct growth and disease outcomes after a salmonid alphavirus challenge.
