Non-indigenous brook trout and the demise of Pacific salmon: a forgotten threat?
Non-indigenous species may be the most severe environmental threat the world now faces. Fishes, in particular, have been intentionally introduced worldwide and have commonly caused the local extinction of native fish. Despite their importance, the impact of introduced fishes on threatened populations of Pacific salmon has never been systemically examined. Here, we take advantage of several uniq...
متن کاملAn investigation on the effects of juvenile rainbow trout (Oncorhynchus mykiss) and brook trout (Salvelinus fontinalis) monoculture and duo-culture farming in freshwater and seawater on growth performance
The objective of this study was to compare growth performance and feed conversion ratios of rainbow trout (Oncorhynchus mykiss) and brook trout (Salvelinus fontinalis) juveniles in monoculture and duo-culture in freshwater and seawater under aquarium conditions. The fish were about 2-months old hatchery-reared brook and rainbow trout with initial weights of 0.934±0.033 (n=360) and 1.014±0.019 (...

متن کاملDifferences in metabolic response to Loma salmonae infection in juvenile rainbow trout Oncorhynchus mykiss and brook trout Salvelinus fontinalis.
Routine and post-exercise metabolic rates were measured for juvenile rainbow trout Oncorhynchus mykiss and brook trout Salvelinus fontinalis infected with the microsporidium gill parasite Loma salmonae under laboratory conditions. Rainbow trout increased routine and post-exercise metabolic rate in response to infection compared with controls. Brook trout, on the other hand, lowered routine meta...
متن کاملA comparative examination of cortisol effects on muscle myostatin and HSP90 gene expression in salmonids.
Cortisol, the primary corticosteroid in teleost fishes, is released in response to stressors to elicit local functions, however little is understood regarding muscle-specific responses to cortisol in these fishes. In mammals, glucocorticoids strongly regulate the muscle growth inhibitor, myostatin, via glucocorticoid response elements (GREs) leading to muscle atrophy. Bioinformatics methods sug...
