Abstract:
This experiment of four months on Oncorhynchus mykiss stocking density, growth performance, and survival rate were measured in the cages of Koldam Reservoir in Bilaspur, Himachal Pradesh. During this study, 10,000 rainbow trout fingerlings with an average weight of 5g were raised in net cages with size of 643 meters long. This experiment was performed just to understand the survival rate and growth of rainbow trout under cages (Koldam Reservoir) in lentic conditions with minimum flow of water during these months. Moreover, many factors influenced survival rate and growth of Rainbow Trout (O. mykiss) fingerlings, including water quality parameters such as water temperature, pH and food quality under cage culture. In the current study, the total average weight gain was 33 g, and the total average length gain was 17cm throughout the study period. Despite a total stocking density of 10,000, just 30% of the fish fingerlings survived in the cages of Koldam Reservoir in Bilaspur, Himachal Pradesh. The most critical element impacting growth was temperature, which resulted in considerable death of fish fingerlings in cages during early phase of study.
