RAINBOW TROUT FARMING IN THE ARTIFICIAL CONDITIONS OF TRANSBAIKAL REGION
Fishing is poorly developed in Transbaikal region, therefore, the construction of a trout farm “Velikiy Istok” is promising and unique in the region. The work was carried out in the period 2016 - 2019. Trout farm is an organization of a large-scale fish farming complex in the Chita district. Currently, the farm has more than 75000 rainbow trout fry with an average weight of 10 grams, obtained in their own incubation workshop from fertilized eggs produced by Troutlodge Inc. (USA, Washington), imported into Russia by permission of the Rosselkhoznadzor. After additional incubation, 106368 pre-larvae were obtained, of which about 99000 larvae floated and switched to external feeding. Larvae developed in the second trays of the Schuster incubation apparatus. The necessary equipment for the incubation workshop of the incubation-fry unit was supplied by LLC “Aquasystems RATZ”. The industrial production of trout in the closed-loop water supply (CWS) with transplantation of bred fish into summer ponds with growing into a marketable form in intensive form has a number of indisputable advantages over fish rearing only in CWS or only in ponds. Fish cultivation in the CWS is considered the fastest and most controlled process of commodity production. Perhaps only one thing can be attributed to the disadvantages of ultrasonic testing: the high cost of farmed fish, the highest among all forms of fish farming. So, all the fry coming for stocking in reservoirs of the Trans-Baikal Territory is bought in specialized farms of neighboring regions (Buryatia, Irkutsk region). Transportation of fry in time is from 10 hours to a day or more. Even the availability of specialized equipment and vehicles does not guarantee the safety of planting material is higher than 75%.
