Differential Adaptation

Hybridization between rainbow trout (Oncorhynchus mykiss (Walbaum, 1792)) and westslope cutthroat trout (Oncorhynchus clarkii lewisi (Girard, 1856)) occurs commonly when rainbow trout are introduced into the range of westslope cutthroat trout. Typically, hybridization is most common in warmer, lower elevation habitats, but much less common in colder, higher elevation habitats. We assessed the tolerance to cold water temperature (i.e., critical thermal minimum, CTMin) in juvenile rainbow trout and westslope cutthroat trout to test the hypothesis that westslope cutthroat trout better tolerate low water temperature, which may explain the lower prevalence of rainbow trout and interspecific hybrids in higher elevation, cold-water habitats (i.e., the “elevation refuge hypothesis”). All fish had significantly lower CTMin values (i.e., were better able to tolerate low temperatures) when they were acclimated to 15 °C (mean CTMin = 1.37 °C) versus 18 °C (mean CTMin = 1.91 °C; p < 0.001). Westslope cutthroat trout tended to have lower CTMin than rainbow trout from two populations, second–generation (F2) hybrids between two rainbow trout populations, and backcrossed rainbow trout at 15 °C (cross type × acclimation temperature interaction; p = 0.018). Differential adaptation to cold water temperatures may play a role in influencing the spatial distribution of hybridization between sympatric species of trout.

Food And Nutritional Security

Recently, aquaculture technology of cold water Rainbow trout (Oncorhynchus mykiss) has been popular among farmers in hills and mountains of Nepal Himalaya.  Production of rainbow trout started in government and private farms in 1995 and 1998, respectively. At present the rainbow trout farming has expanded in several mountain districts with rapidly growing demand in others adjacent areas.  The total farmers have increased from none to 85 producing more than 180 metric ton from 16 districts by employing about 550 people in year 2012. The trout aquaculture technology could be expanded in areas having pristine, cold and clean water resources having road access for market destinations close to urban areas of all Trans Himalayan countries as a means to food and nutritional security, and employment opportunities in mountainous regions.
