Abstract :
This research is aimed at obtaining technology, increasing production and profitability, promoting and diversifying in tropical fish farms, as well as breeding and breeding marine fish far from the sea coast, in order to release the fry into the sea, in order to increase productivity and increase the stocks of this fish. The improvement of the living conditions of the fishermen was done. Sea carp breeding was carried out as a single species and in the same density format with 1400 pieces with an average weight of 42.46 ± 0.05 in 3 pools with an area of 0.5 hectares in tropical fish farms. The required fry were supplied from the Voshemgir dam center and released in breeding ponds. From the beginning of the breeding period, they were fed with natural food and farmed carp concentrate at the rate of 5-10% of their body weight. At the end of the breeding period, the average weight of this fish was 722.49 ± 0.10, the average daily growth was 3.44, the value of the food conversion coefficient was 2.30, and its survival rate was 85.83%, which indicates the adaptability of this species to the conditions The climate and breeding farms of this province and its breeding and production in the areas far from the sea shores are single-species and together with tropical fishes. For this reason, breeding of this species in order to increase the production and profitability of the aquaculture industry, as well as its production and reproduction in order to improve the stocks of this species in the sea, it can be suggested to breed it in tropical fish farms in the province.
