In many countries a focus for freshwater and marine aquaculture is traditionally fish. In the balance of meat of our country’s fish production is 25%, it is used in more than 50 industries.
Production of food fish products has high economic efficiency. So, 70 million tonnes of fish, invertebrates and other water bodies (excluding whales) in protein content is equivalent to a herd of 400 million heads of cattle. The costs for producing 1 kg of fish protein is almost 3 times lower than the costs associated with obtaining 1 kg of meat protein products.
In addition to food production, the fishing industry provides raw materials for medical industry (fat, vitamins, medicines), food products (flour, minced fish, forage fish), fertilizer, leather, fur, ambergris, etc.
