Fish oil is an important constituent in aquafeed industry because of its high proportions of n-3 long-chain polyunsaturated fatty acids (LC-PUFA) that play an important role in supporting normal growth, health, and nutritional quality of farmed aquatic animals.
Advantages:
Fish oil is an excellent lipid source, especially in terms of HUFAs and PUFAs.
Fish Oil has greater abundance of EPA and DHA. Fish oil especially body oil are rich in triacylglycerols (TAGs), which comprise the major component of stored fats, generally contributing in excess of 90% of the total fatty acid composition. It offers major benefits to animal health, including improved immunity against disease, higher survival and growth, and reduced incidences of deformities. It is considered to increase feed appeal. This encourages farmed fish and crustaceans to locate feed and increases consumption, thereby reducing wastage. It is highly digestible, which leads to increased growth and less wastage of food.
