Abstract :
AbstractNatural and semi-natural water resources with proper planning can be used for the production of aquatic, especially fish, and it is necessary to first assess the ecological factors and production potential. Then, the optimum cage culture number in a field was calculated based on maximizing the area of the appropriate farming and taking into account the confidence interval of about 80 meters. The results indicate 80, 80 and 100 cage culture in each region for cold water cultivation, respectively. Considering the 80 meter confidence distances and the optimal number of cage culture, the method of arrangement of cold-water fish farms in Golestan Dam was determined. According to the established design, the area suitable for the cultivation of cold water is 10 hectares (20 farms with 80 cage culture), 10 hectares (20 farms with 80 cage culture) and 12 hectares (25 farms with 100 cage culture), respectively. It should be noted that the minimum depth required for the establishment of cages for fish farming should be 3.3 meters in order to be able to farming. In general, if the depth of the water at the cage's position at the time of the introduction of the baby is at least 5 to 6 meters, the area of 32 hectares and the establishment of the cage, approximately 108 tons of fish can be harvested. If the water depth of the cage is less than 4 meters, about 60 tons of salmon can be caught.
