History of fish farming in Iran
The first artificial reproduction of fish in Iran dates back to ****, which began with the reproduction of sturgeon fish, but the cultivation of tropical fish in Iran dates back to the 40s. The need to remove fodder in the Anzali wetland forced the government of the time to fight against the higher plants grown in the lagoon, which after death increases the amount of sediments and reduces the amount of dissolved oxygen in the water. As a result, he introduced Amur fish from Russia and China to this ecosystem. Due to the reception of cultivated fish, breeding centers were also established in the country.

The characteristics of fish farming
Fish growth and the factors that influence their growth process are of primary importance for fish breeders. Because the maximum growth of the fish in the minimum period of time with the minimum amount of food is his main goal. Fish is a cold-blooded animal and does not have to expend energy to maintain its body temperature. In this sense, a fish is more efficient and capable than a warm-blooded animal, in terms of converting food into body protein. The weather changes. Springs and wells are created due to the infiltration of rainwater in the ground, which are exploited for the breeding and reproduction of fish. If the total fresh water used to fill the pool is not enough to supply the pool water at certain times of the year, building a water storage tank will enable growers to store water during times of drought and shortage. and use.
