Abstract

This study was conducted in order to investigate the feasibility of warm water fish breeding in the catchment area of Khairabad and Maron rivers in Kohgiluyeh and Gachsaran cities. According to the results, the biological value of Maroon river water is highly polluted in terms of quality, and Khairabad river is considered as relatively polluted river. In Khairabad river, the temperature range is proportional to some extent and is in accordance with the standard. In the Maron River, at the time of investigation, the average water temperature varied from 13°C in February to 26°C in July, which, taking into account the temperature of 16-28°C in warm water fish life, is proportional to It is the standard temperature for raising carp fish. Due to the heavy rains and the occurrence of floods and mudslides, it is necessary to use the river water indirectly by digging drains on the banks of the river. The minimum flow rate, i.e. 1.5 cubic meters per second, is considered as the basis for calculating the production capacity of tropical fish in the region in the 30 km accessible route from the length of the river to the lake of the Maroon Dam. Nevertheless, taking into account the distance of 2 to 3 kilometers to carry out the process of self-purification of river water after entering the effluent of each farm, as well as the limited access to river water in some places and the limitation of land and facilities, the number of 10 warm water fish farms With a concrete structure, the capacity of each farm is 250 tons, and the total capacity of cultivation on the river bank was estimated at 2500 tons.
