FISH MEAL AND FISH OIL REPLACEMENT FOR AQUA FEED FORMULATION BY USING ALTERNATIVE SOURCES : A REVIEW

摘要

Aquaculture is fastest growing food producing sector in the world. It is contributing nearly half to the global foodfish consumption. The total Indian fish production is estimated as 12.60 million metric tonnes, from which 65% is from inlandsector and about 50% of total production is from culture. The total global aquaculture production reached up to 83.6 Mt. Thegrowth of aquaculture increases tremendously in compare to capture fisheries. In the aquaculture production system feedrepresent major cost for growth and survival of fish. Fishmeal and fish oil are major proteinand lipid sources mainly used forfeed formulation in the aquaculture feed industry. Nowadays, the supply of quantity of fishmeal and fish oil in aqua feed has beensignificantly decreases. This is mainly due to the less catch comes from capture fishery and ultimately results in increasingcosts of fishmeal and fish oil.The price of fishmeal and fish oil has increased significantly to over US $ 1600 and US $900-1800per Mt. So with the growing aquaculture industry, supply of fishmeal and fish oil cannot remain sustain. Therefore, we need tohour utilized the alternative protein and lipid sources for continue increases aquaculture production. This can replace shortageof fishmeal, fish oil and also maintain aquaculture industry. There are so many alternative protein and lipid sources easilyavailable mainly from animal, plant origin and other sources. Which can replace the nutritional profile of fishmeal and fish oilwithout compromising growth rates and also available in much cheaper price in general market.
