Aquaculture engineering is a multidisciplinary field of engineering that aims to solve technical problems associated with farming aquatic vertebrates, invertebrates, and algae. Common aquaculture systems requiring optimization and engineering include sea cages, ponds, and re-circulating systems. Benefits of Aquaculture: Alternative food source. Fish and other seafood are good sources of protein, Alternative fuel source, Increase Jobs in the market, Reduce Sea Food Trade Deficit, Creates Barrier against pollution with mollusc and sea weed, Reduces fishing pressure on wild stock. Some examples of aquaculture include raising catfish and tilapia in freshwater ponds, growing cultured pearls, and farming salmon in net-pens set out in a bay. Fish farmingis a common kind of aquaculture. The farming of fish is the most common form of aquaculture. It involves raising fish commercially in tanks, fish ponds, or ocean enclosures, usually for food.
