Expression of corticoid‐regulatory genes in the gills of Atlantic salmon (Salmo salar) parr and smolt and during salinity acclimation

open access: yesJournal of Fish Biology, EarlyView.
Abstract In teleost fishes, cortisol is the major corticoid and has both glucocorticoid and mineralocorticoid actions. However, how fish tissues discriminate between these distinct corticosteroid actions is unclear. In mammals, the major factors responsible for intracellular corticosteroid regulation are glucocorticoid receptors (grs) and the ...

Genes, fish and fisheries: translating science into policy

open access: yesJournal of Fish Biology, EarlyView.
Abstract The 2024 Annual Symposium of the Fisheries Society of the British Isles reviewed the burgeoning impact of ‘omics’ technologies on fish ecology, management and forecasting. As with life sciences more generally, major advances in speed, cost‐effectiveness and breadth of applications in ‘omics’ has had profound societal and environmental impacts.

Red sea bream iridoviral disease

open access: yesUirusu, 2005
The first outbreak of red sea bream iridoviral disease caused by red sea bream iridovirus (RSIV) was recorded in cultured red sea bream Pagrus major in Shikoku Island, Japan in 1990. Since 1991, the disease has caused mass mortalities of cultured marine fishes not only red sea bream but also many other species.

Divergent survival and viral shedding patterns of red sea bream iridovirus in black sea bream and Japanese sea bass

open access: yesJournal of Fish Biology, EarlyView.
Abstract In open marine aquaculture, rearing diverse fish species in adjacent net pens facilitates the waterborne spread of red sea bream iridovirus (RSIV). This study systematically evaluated the horizontal transmission dynamics of RSIV in black sea bream (BSB, Acanthopagrus schlegelii) and Japanese sea bass (JS, Lateolabrax japonicus) under immersion
