Extract

There is considerable interest in the cultivation of salmonids in several countries. In Norway it is now a question of rate of expansion rather than a question of whether this industry will develop or not. Interest is turning more and more towards sea farming based on Atlantic salmon rather than on rainbow trout.

One of the most important economic factors in fish fanning is the producing ability of the fish. It is essential for the future expansion of fish farming that one develops a more productive animal which is better adapted to captivity.
