Abstract

The fisheries and aquaculture remain important sources of food, nutrition, income, and livelihoods for hundreds of millions of people around the world. With the advancement of the fisheries sector, new techniques of culture and betterment of culture systems for the blue revolution have been done. One such system is integrated multi-trophic aquaculture (IMTA). IMTA is the intensive and synergistic cultivation using water-borne nutrients and energy transfer between various species occupying different trophic levels. It provides the byproducts including waste from one aquatic species as input (fertilizer, food) for another. IMTA promotes economic and environmental sustainability by converting byproducts and uneaten feed from fed organisms into harvestable crops, thereby reducing and increasing economic diversification. Many projects on IMTA have been done in different countries. The use of multiple organisms from different trophic levels is possible and extremely productive in aquaculture. IMTA has all the potential to boost the blue revolution in near future.
