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 کاملPhysiological modulation of iron metabolism in rainbow trout (Oncorhynchus mykiss) fed low and high iron diets.
Iron (Fe) is an essential element, but Fe metabolism is poorly described in fish and the role of ferrireductase and transferrin in iron regulation by teleosts is unknown. The aim of the present study was to provide an overview of the strategy for Fe handling in rainbow trout, Oncorhynchus mykiss. Fish were fed Fe-deficient, normal and high-Fe diets (33, 175, 1975 mg Fe kg(-1) food, respectively...
متن کاملSupplementation of taurine and methionine to all-plant protein diets for rainbow trout (Oncorhynchus mykiss)
Taurine has been demonstrated to be a conditionally indispensable nutrient for several carnivorous fish species. Currently, trout feeds contain reduced levels of fishmeal which had been the primary source of dietary taurine. The reduction of fishmeal in the diet, and thus dietary taurine, may limit growth. A 12-week feeding trial was conducted using a factorial treatment design with taurine sup...
متن کاملEvaluation of family growth response to fishmeal and gluten-based diets in rainbow trout (Oncorhynchus mykiss)
A study was conducted to evaluate genotype×feed interactions in a commercial strain of rainbow trout (Oncorhynchus mykiss). Microsatellite DNA markers were used to determine the pedigree of the top 1% and bottom 1% of progeny in a large scale commercial growth trial of 24,000 rainbow trout from 20 full-sib families (20 dams×10 sires in a nested mating design). The progeny were pooled at eyed st...
متن کاملTaurine Supplementation of All-plant Protein Diets for Rainbow Trout (Oncorhynchus mykiss)
—Taurine has been demonstrated to be conditionally indispensable for several carnivorous fish species. Current trends in trout production include decreasing levels of fish-meal content in feeds, along with faster growing strains of fish. Taurine may be a limiting nutrient in support of elevated planes of growth for rainbow trout. A 9-wk feeding trial was conducted using a factorial treatment de...
