A global analysis shows that thermal fronts often separate fishing activity between warm and cold waters, an effect obscured when fronts are treated only as aggregation zones.
Guppies housed with plants showed favourable behavioural indicators, while lower basal cortisol occurred only in the treatment containing three plant species.
A seven-solvent study shows that the vehicle can alter zebrafish larval locomotion and confound behavioural results unless controls are carefully designed.
A longitudinal survey of six freshwater exhibits shows how water microbiome profiles may complement health surveillance without replacing clinical assessment or targeted diagnostics.
Iodophor treatment reduces viral contamination on salmonid egg surfaces, but it must remain part of a documented, multi-barrier hatchery biosecurity plan.
A survey of 3,253 wild amphibians links Batrachochytrium dendrobatidis detection with temperature and human disturbance, without establishing causation.
Whole-brain RNA sequencing, CRISPR perturbations and T3 exposure identify a thyroid–klf9–ATPase pathway associated with aggregation and alignment in Danionella cerebrum.
A field study in Idaho found frequent, externally hidden spinal injuries in salmonids and measured pulse multiplication when three unsynchronised backpack electrofishers worked in overlapping fields.
