The production of farmed fish, especially trout in Iran, has found a special place in the diet of people due to the taste of this fish and its popularity among consumers. Considering the potential of aquaculture and the long-term horizons of the country's fisheries development, it is very important for the country to produce fish feed quality quantitatively and qualitatively in accordance with the country's development plans and increase the economic efficiency of aquaculture. The growing population, the reduction of marine reserves and catching fish, the increase in global demand for aquaculture, has led to the development of aquaculture as a necessity. In this regard, high value-added aquaculture is a strategic approach to maintaining marine resources and providing valuable marine protein. Feed as a feedstock for aquaculture has high added value.
