such as poultry, pigs and aquaculture.
Hitherto, part of the aquaculture production relies on wild fish harvests,
as fishmeal and fish oil are essential elements of the diet of
many aquaculture species, both carnivorous and herbivorous fish
and shrimp. About 5–6 million tonnes of low-value/trash fish are
used as direct feed in aquaculture worldwide either provided without
processing or as part of farm made feeds (FAO, 2009). FAO (2009)
reported that the total amount of fishmeal and fish oil used in
aquafeeds is estimated to have grown more than threefold between
1992 and 2006, from 0.96 million tonnes to 3.06 million tonnes and
from 0.23 million tonnes to 0.78 million tonnes
