Sea fish meal is one of the best sources of feed for livestock, poultry and seafood. Protein in marine fish meal is always better than other types of protein that are easy to digest and essential amino acids.

Marine fish meal is protein rich, containing between 55% and 67% of total protein, of which protein absorption and absorption is 80-95% depending on processing technology and raw materials. Whereas the protein digestibility of plant sources is only 30-40%.
Protein of marine fish meal is a perfect protein, as they contain enough amino acids and have a balanced ratio of amino acids. Marine fish meal has a high digestibility factor, which is rich in soluble protein and absorbed.

Marine fish meal is the most valuable ingredient in fish feed and, furthermore, it is a key ingredient in the diet of fish and shrimp. It has good taste and quality, providing enough protein with essential fatty acids. In terms of economics, it is the only source of protein in fish feed. This is also the case with salmon. It is a good source of energy and its oil also has the corresponding ingredients like vitamins, minerals and other trace elements. However, it has a high content of phosphorus and is easily polluted. High quality marine fish meal is a good active ingredient in fish feed. Fish meal improves disease resistance (for animal feed) particularly in the early stages of life. This may also be true for aquatic food.

Sea fish meal is the best food for bone and crustacean fish, with outstanding quality and high protein content. Poor processing and storage, however, lowers amino acids, lipid oxidation, and is responsible for the production of antimicrobial agents such as histamine and gizzerosin, which may affect fish but may not. To shrimps - species without gastric acid type in the right sense. These and other amines were discussed extensively by Pike and Hardy (1994). Chamberlin (1993) notes that salmon have poor tolerance for histamine and gizzerosin, while almost no information is available on the effect of fishmeal on all other species. However, Pike and Hardy (1994) in the UK have confirmed that the use of broken fish meal, mold with high levels of histamine and tyramine, will reduce the growth rate of black tiger shrimp.

The addition of marine fish meal to aquafeed feeds also has some differences, depending on the species, the stage of development of the species will correspond to the diet and the corresponding nutrient composition. The inclusion rate, currently limited from a low of 5% in catfish feed to 60% in marine fish feed. In general, the extra marine fish meal is expected to decrease by 2000 but will still reach 40% or more for all skeletal fish except salmon and catfish. The addition rates for salmon (30%) and shrimp (25%) are not expected to be achieved during this period. However, it depends on the case, which may be increased in intensive aquaculture but at a lesser degree of greed, it may be reduced.
