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.
A 2025 case report describes rapid clinical improvement in nine marine fish after hydroxychloroquine exposure. Its uncontrolled design makes it a prompt for stronger diagnostics, quarantine and drug monitoring—not a dose to copy.
Virus-like nodavirus particles carried inside Lactococcus lactis reduced brain viral load in orally vaccinated Asian seabass, offering a promising but still experimental platform.
A study involving twelve Xenopus laevis obtained embryos by simulating spring and rainfall rather than injecting hCG. The feasibility signal is encouraging, but refinement and reduction still require comparative measurement.
An experimental study links viral load, gill damage and physiological stress in koi exposed to carp oedema virus, with sharply different responses at 12 and 18°C.
A retrospective study describes 63 tumours in 62 fish from 37 species and shows why a visible mass requires longitudinal records, purposeful imaging and histological confirmation.
An 84-day rainbow trout trial found no detectable health penalty when Tetraselmis chui biomass replaced part of the fish-oil fraction, but commercial validation still requires longer, farm-specific testing.
An analysis of 1,105 sites finds that species diversity and habitat mosaics can dampen fluctuations in river fish communities exposed to human pressure.
