The modern condition of rainbow trout Parasalmo mykiss from the Kolsai lakes
AbstractIn order to increase the fish productivity of water bodies and the rational use of aquatic animals inKazakhstan, acclimatization events have been repeatedly held. Acclimatization work touched almost allthe reservoirs of the republic, including the mountain. The peculiarity of abiotic indicators of mountainreservoirs impoverishes the species diversity of aquatic organisms, and in order to increase biodiversityand rational use of the reservoir, rainbow trout was brought. In the middle of the 20th century, rainbowtrout from reservoirs was acclimatized to the Kolsay lakes. Currently, several aboriginal species inhabitthe pond, but only rainbow trout is of commercial importance. The paper presents data on the currentstate of rainbow trout Parasalmo mykiss (mikizha), analyzed materials for several years. According tothe results of biological indicators, it was revealed that the main dimensional weight indicators remainstable. The significance of biological traits on the lower Kolsay lake is higher compared to the averageKolsay. The research catch was both young and old-aged individuals of fish, large individuals are notfound annually. The food supply for fish is sufficient, as evidenced by the data on fatness.Key words: acclimatization, rainbow trout, Kolsay lake, native species, biological features
