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 کاملLinking Personality to Larval Energy Reserves in Rainbow Trout (Oncorhynchus mykiss)
There is a surging interest in the evolution, ecology and physiology of personality differences. However, most of the studies in this research area have been performed in adult animals. Trait variations expressed early in development and how they are related to the ontogeny of an animal's personality are far less studied. Genetic differences as well as environmental factors causing functional v...
متن کاملEffect of dietary protein and energy levels on rainbow trout (Oncorhynchus mykiss) reared in brakish water
A completely randomized design, with 3×3 factorial arrangement, was conducted to test various ratios of dietary protein to energy (P/E) for rainbow trout, reared in brackish water. Three crude protein levels (35, 40 and 45%) and three energy levels (370, 400 and 430 Kcal/100g) at each protein level were utilized. Semi-purified diet containing fish meal, casein and gelatin as the sources of prot...
متن کاملEnergy allocations to xenobiotic transport and biotransformation reactions in rainbow trout (Oncorhynchus mykiss) during energy intake restriction.
Limited energy intake may result in the down-regulation of cellular defense mechanisms, or if maintained, result in trade-offs with other physiological systems. To examine this, juvenile rainbow trout (Oncorhynchus mykiss) were fed full-rations (1.17% body weight [BW]/day), half-rations (0.59% [BW]/day), or fasted for 9 weeks followed by refeeding at full-rations. BW and liver somatic index (LS...
