Why farm fish ?
More than 70% of the earths surface is covered by water, creating a vast potential food supply from aquatic sources, which tend to have a lighter environmental footprint than land-based food systems. In recent years, the international scientific community appears to be reaching a consensus that, properly managed aquaculture can be more environmentally benign than alternative food production methods.[1] In most of the world, fish is a much cheaper protein source than land-grown meat, and is therefore an increasingly critical resource for people the world over. Globally, fish and shellfish provided approximately 16% of the protein consumed by humans (in 1993). In developing countries, this figure is about 21%; in more than 20 developing countries located in Asia and Africa (including relatively populous countries such as Bangladesh, Indonesia, Tanzania, Ghana, and Uganda), the foodfish share of animal protein is one-third or more.[2] However, rapid improvements in fishing technology, cou
