Abstract :

Abstract[1] Fish cage culture due to global demand in recent years has increased dramatically and now as the fastest way in response to global needs, especially in developing countries. Forecasts show that in developing countries, fish consumption up to 57% from 1997 (62.7 million tons) to 2020 (98.6 million) increase. Studies in Iran, did not receive continuous on the cage culture. The study area was the southern part of Caspian Sea. The study objectives include determining areas and introduced species of fish farm with an emphasis on depth and some physical and chemical parameters (temperature, salinity and dissolved oxygen) in various layers of the water and were in different seasons. The results showed that in the south central area of the Caspian Sea in Mazandaran province, as has been the best part. Also, the use of floating cages less than 20 meters in depth, it is necessary that the temperature of the fish used 26 °C is tolerated in the summer. Otherwise it must be immersed in the cage and the establishment of more than 20 m depth is used. * Corresponding authors; [e-mail]
