Transcriptome profiling of posterior kidney of brown trout, Salmo trutta, during proliferative kidney disease

Parasites & Vectors, 2019
Background Tetracapsuloides bryosalmonae is a myxozoan parasite which causes economically important and emerging proliferative kidney disease (PKD) in salmonids.

Modelling brown trout spatial requirements through physical habitat simulations

, 2010
Territorial behaviour is often considered the main mechanism regulating salmonid populations and territory size regarded as the proximate factor that limits abundance, being mainly determined by body size. Despite the spatial requirements of young‐of‐the‐

Ecological energetics of an imperilled fish: Physiological metrics, experimental protocols and implications for population recovery

Journal of Fish Biology, EarlyView.
Abstract Insights about fish physiology can be useful for population management, but collecting ecologically relevant data can be challenging, especially for imperilled and sensitive species. With the goal of identifying ecologically relevant physiological metrics, we conducted a range of experiments to characterize the metabolism, food consumption ...

Spawning behaviour between endemic delta smelt (Hypomesus transpacificus) and non‐native Wakasagi (H. nipponensis) in the San Francisco estuary

Journal of Fish Biology, EarlyView.
Abstract In the San Francisco Estuary, non‐native Wakasagi Hypomesus nipponensis hybridize with endemic and endangered Delta Smelt H. transpacificus, and all wild‐caught hybrids have a maternal Wakasagi parent. However, the mechanisms that facilitate or impede hybridization and explain sex‐biased hybrid asymmetry between these two species remain ...

Post‐release survival, movement and marine migration of smolt‐to‐adult supplemented Atlantic Salmon

Journal of Fish Biology, EarlyView.
Abstract Atlantic salmon (Salmo salar) populations are declining across much of their range, prompting the use of supplementation strategies, such as smolt‐to‐adult supplementation (SAS), to enhance adult returns. However, little is known about how captivity while maturing to adulthood influences post‐release survival, behaviour and migration of ...

Spot the difference: Turbidity‐driven plasticity and variation in spotted grunter (Pomadasys commersonnii) spot patterns

Journal of Fish Biology, EarlyView.
Abstract Animal body markings such as spots, stripes and patterns play important roles in camouflage and visual communication. This study investigated phenotypic plasticity in the spot patterns of spotted grunter Pomadasys commersonnii, an estuarine‐dependent haemulid species.

Food selectivity and grazing responses of the Lawnmower Blenny (Salarias fasciatus) to nutrient enrichment and ammonia exposure

Journal of Fish Biology, EarlyView.
Abstract Nutrient enrichment can alter the nutritional quality of the epilithic algal matrix (EAM) and modify the feeding environment of herbivorous and detritivorous reef fishes. However, wastewater inputs can also elevate ammonia concentrations, which may disrupt fish physiological processes, yet the effects of ammonia exposure on grazing activity ...

A long-term study of the impact of the invasive species Eurasian minnow Phoxinus phoxinus on brown trout Salmo trutta production in a high mountain lake, Southern Norway

Fauna Norvegica
The shallow Lake Skjerja was originally one of the most outstanding brown trout lakes on the Hardangervidda mountain plateau. During the period 1973–1985, the annual yield was on average 3.35 kg ha-1.
