The rainbow trout, Oncorhynchus mykiss, is one of life's great success stories. It has straddled the worlds of nature and nurture, naturally thriving in a range of temperatures and water quality while responding to domestication so well that it has been spread by human hand from the Pacific R...
Magnetic field perception of the rainbow trout, Oncorhynchus聽mykiss, was demonstrated with a heartbeat conditioning test. The electrocardiogram was measured with subcutaneously inserted silver species of the family Salmonidae. Magnetic field perception of the rainbow trout, Oncorhynchus聽mykiss, was ...
3). These results are consistent with shifts in sex and Omy05 karyotype frequencies within the stream among trout across the migratory size range (>100 mm; Fig. 3b,c). The best-fit model of migratory tendency includes sex-dependent dominance of the Omy05 rearrangement, where the ...
Then, during the second phase (Winter: December–March; 103 days), rainbow trout were added in the tanks resulting in a polyculture phase with black bullhead catfish and a second cycle of Swiss chard. During winter, the expected temperature range was below the feeding temperature range of ...
Spermatozoa are the cells that are most commonly used for cryopreservation of valuable genetic resources in aquaculture. It is known that fish spermatozoa transmit to the embryo not only their genetic but also their epigenetic profile, especially DNA met
aThe particular strain of rainbow trout tested may necessitate the use of other temperatures. Brood stock must be held at the same temperature as that to be used for the eggs. After receipt of eggs from a commercial breeder, a short adaptation (e.g. 1-2 h) to test temperature after arri...

Triploid rainbow trout is a hypoxia-sensitive fish species, and is susceptible to death in summer with high water temperature induced acute hypoxia. The study was conducted to evaluate the effect of high protein diet and high carbohydrate diet on hypoxic tolerance of triploid rainbow trout. Two is...
Although the size of the eggs produced by triploid recipients that received in vitro-expanded ASGs was slightly smaller than those produced by normal diploid female trout (2N cont), the triploid recipient egg sizes were still within the normal range for rainbow trout18 (Fig. 4b). The milt ...
alongside the full substitution of FO with VeraMaris®natural algae oil and rapeseed oil in the diet of rainbow trout (O. mykiss). The impact on fish growth performance, gut and liver morphology, production of volatile fatty acids in the gut, lipid metabolism indices, and fatty acid profile...
