Here's a Science Daily report on a Norwegian effort to suck up
salmon-farming wastes into useful organisms...
http://www.sciencedaily.com/releases/2012/11/121123092744.htm
Waste from salmon production is currently being discharged into
Norwegian coastal waters. Researchers say this is a resource -- worth
NOK 6 billion each year -- that should be exploited for new biological
production.
In 2009 Norwegian fish farms produced over a million tonnes of salmon
and salmon trout; nearly 1.2 million tonnes of high-quality feed went
into this production. But a considerable amount of feed administered
is released to the surrounding waters as respiratory products, faeces
and uneaten feed .
This means that a significant portion of the aquaculture industry's
feed is actually wasted on fertilising the ocean with both organic and
inorganic nutrients. The value of these nutrients is estimated at NOK
6 billion annually
