Title Fish waste utilisation in India

Abstract Processing of fish leads to enormous amounts of waste. It is estimated
that fish processing waste after filleting accounts for approximately 75%
of the total fish weight. About 30% of the total fish weight remains as
waste in the form of skins and bones during preparation of fish fillets.
This waste is an excellent raw material for the preparation of high value
products including protein foods. The utilization of fish wastes help to
eliminate harmful environmental aspects and improve quality in fish
processing. Fish processing generates solid wastes that can be as high
as 50-80% of the original raw material. Skin and bone are sources of
high collagen content. An important waste reduction strategy for the
industry is the recovery of marketable byproducts from fish wastes.
Hydrolyzed fish wastes can be used for fish or pig meal as well as fertilizer
components. The three most common methods for utilization of aquatic
waste (either from aquaculture or wild stock) are the manufacture of
fishmeal and oil, the production of silage and the use of waste in the
manufacture of organic fertilizer. The utilization of by-products is an
important cleaner production opportunity for the industry, as it can
potentially generate additional revenue as well as reduce disposal costs
for these material.
