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 کاملGenetic diversity in Chilean populations of rainbow trout, Oncorhynchus mykiss
The rainbow trout Oncorhynchus mykiss, was first introduced in Chile between 1905 and 1920 and is currently widely distributed in Chile from Antofagasta (23°S) to Patagonia (55oS). The broad range of the geographic and climatic distributions of this species in Chile offers a unique opportunity to study the effect of naturalization of an introduced species on its genetic variability. It is of pa...
متن کاملGenetics of Microenvironmental Sensitivity of Body Weight in Rainbow Trout (Oncorhynchus mykiss) Selected for Improved Growth
Microenvironmental sensitivity of a genotype refers to the ability to buffer against non-specific environmental factors, and it can be quantified by the amount of residual variation in a trait expressed by the genotype's offspring within a (macro)environment. Due to the high degree of polymorphism in behavioral, growth and life-history traits, both farmed and wild salmonids are highly susceptib...
متن کاملImmersion vaccination of rainbow trout (Oncorhynchus mykiss) against Flavobacterium psychrophilum
Flavobacterium psychrophilum is the causal agent of rainbow trout fry syndrome (RTFS), which seriously affects rainbow trout aquaculture. The disease affects fish at early life stage and can cause high mortality. Within trout aquaculture several procedures have been implemented in order to reduce the disease problem. Use of ”Flavo free” broodstock and disinfection of eggs can reduce probability...
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...
