earthworms <strong>and</strong> <strong>in</strong> turn can be processed to quality human food. It is said that <strong>the</strong>re<br />

are 200 k<strong>in</strong>ds of food from earthworms <strong>in</strong> <strong>the</strong> U.S.A (Kangm<strong>in</strong>, 2005). Earthworms<br />

are <strong>the</strong> future of seafood. Not yet, but <strong>the</strong>y will be (Sh<strong>in</strong>er , 2009).<br />

The key to <strong>the</strong> multi-pronged success of earthworms as aquaculture fodder is <strong>the</strong>ir diet<br />

of organic wastes. L<strong>and</strong>-based pollution, such as fester<strong>in</strong>g animal manure, is an<br />

enormous problem <strong>for</strong> coastal fisheries impacted by runoff. Brita<strong>in</strong> alone produces 84<br />

megatons of cow manure, 9 megatons of pig waste <strong>and</strong> 5 megatons of chicken waste<br />

each year, much of which flows to <strong>the</strong> coast as runoff. This pollution is a significant<br />

contributor to <strong>the</strong> decl<strong>in</strong><strong>in</strong>g productivity of wild fish stocks, as fish struggle to cope<br />

with <strong>the</strong>ir heavily contam<strong>in</strong>ated environment. Earthworms solve this problem by<br />

convert<strong>in</strong>g l<strong>and</strong> animal wastes <strong>in</strong>to high-prote<strong>in</strong> aquaculture feed. Earthworms<br />

convert cow manure <strong>in</strong>to dry matter at a remarkable 10 percent clip, such that<br />

Brita<strong>in</strong>‟s 84 megatons of cow manure could produce 8.4 megatons of dehydrated
