Rainbow Trout, Oncorhynchus mykiss
Rainbow trout are classified as Oncorhynchus mykiss, and as such belong to the same genus as Pacific salmon, and to the family Salmonidae, which includes Atlantic salmon (Salmo salar), various trout (Salvelinus sp.), Arctic char (Salvelinus alpinus), Arctic grayling (Thymallus arcticus) and whitefish (Coregonus sp.). Rainbow trout are native to areas around the North Pacific Ocean, from souther...
متن کاملCreatine metabolism differs between mammals and rainbow trout (Oncorhynchus mykiss)
Creatine plays an important role in the cell as an energy buffer. As the energy system is a basic element of the organism it may possibly contribute to differences between rainbow trout strains selected for the traits growth and robustness, respectively. The cDNA sequences of creatine-related genes encoding glycine amidinotransferase (GATM), guanidinoacetate N-methyltransferase (GAMT), creatine...
متن کاملSerotonin-induced brain glycogenolysis in rainbow trout (Oncorhynchus mykiss).
In this study, we evaluated the serotonin-mediated control of cerebral glycogen levels in the rainbow trout, Oncorhynchus mykiss. Intracerebroventricular (i.c.v.) administration of serotonin (5-HT) to normoglycemic trout (time and dose response) decreased glycogen levels in the brain and increased brain glycogen phosphorylase activity (time response). In hypoglycemic fish (that had been fasted ...
متن کاملHydrogen sulfide stimulates catecholamine secretion in rainbow trout (Oncorhynchus mykiss).
We tested the hypothesis that endogenously produced hydrogen sulfide (H(2)S) can potentially contribute to the adrenergic stress response in rainbow trout by initiating catecholamine secretion from chromaffin cells. During acute hypoxia (water Po(2) = 35 mmHg), plasma H(2)S levels were significantly elevated concurrently with a rise in circulating catecholamine concentrations. Tissues enriched ...
متن کاملEffect of curcumin and ginger extract on growth and biochemical indices in rainbow trout (Oncorhynchus mykiss)
In this experiment, the effect of curcumin and ginger hydroalcoholic extract on growth performance and biochemical indicators of blood in rainbow trout (Oncorhynchus mykiss) were examined separately and in combination. The experiment was designed in a completely randomized design with zero levels (control), 0.5% ginger hydroalcoholic extract, 0.5% curcumin and 0.5% curcumin composition + 0.5% g...
