Divergent exploratory‐avoidant behavioural strategies may drive niche differentiation in juvenile Antarctic fishes

open access: yesJournal of Fish Biology, EarlyView.
Abstract We used an ecological niche theory framework integrating physiological and behavioural ecology to understand interspecific differentiation of juveniles of four Antarctic fishes: Trematomus bernacchii, Trematomus pennellii, Trematomus nicolai and Pagothenia borchgrevinki.

open access: yesJournal of Fish Biology, EarlyView.
Abstract Significant declines in Atlantic salmon (Salmo salar) populations across their range have prompted an increased use of hatchery supplementation programmes to support population recovery. However, concerns persist regarding the effectiveness of these programmes due to limited understanding of how hatchery‐reared salmon perform post‐release in ...

Challenging Host Specificity: Malacosporean Parasite Dynamics—Tetracapsuloides bryosalmonae Beyond Salmonids—An Infection Experiment

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Proliferative Kidney Disease (PKD) is a severe parasitic disease of salmonids caused by the malacosporean endoparasite Tetracapsuloides bryosalmonae. In the fish intermediate host, the parasite is disseminated via the circulatory system and ultimately reaches the kidney, where it matures before releasing infective spores into the environment ...
