Russia, like no other country in the world, has a huge potential for fish-farming development. According to data of different authors, in Russia from 12 to 16 million hectares of water areas of inland water bodies are suitable for fish-farming. Aquaculture farms potential in Russia is estimated at, at least, 2-3 million tons.
