Freshwater fish - a global food potential [rearing, carps, eels, salmon and trout]

Freshwater fish can significantly supplement the world's supply of dietary protein, although they now form only 15 percent of the total fish protein used for human consumption. Most of the potential increase will probably come from intensively managed fish ponds. Tilapia, trout and carp are the "big three" groups of freshwater species now in cultivation. The future success of a fish pond venture on a large scale depends upon intensive training of pond managers and public acceptance of the product. Fish production in larger bodies of water-lakes, rivers, and reservoirs-will always be important, although water pollution of various types threatens fish populations in many regions of the world.
