Problems solved by technology
It is generally believed that the carbohydrate level in seawater fish feed should not exceed 20%, and the carbohydrate level in freshwater fish feed should not exceed 40%. If the carbohydrate level in feed is too high, the growth of fish will be inhibited, resulting in persistently high blood sugar levels and reduced immune function.

Embodiment 1
[0013] 10kg white fish meal, 50kg soybean protein concentrate, 25kg cornstarch, 5kg fish oil, 3.78kg corn oil, 1kg sodium dihydrogen phosphate, 1kg compound vitamin, 1kg compound mineral, 3kg squid paste, 0.02kg phytase, 0.3kg compound Amino acids are mixed into 100kg of dry feed for black sea bream, wherein the compound amino acids contain 0.06kg of lysine, 0.12kg of methionine, and 0.12kg of tyrosine; then add 20Kg of water, stir, granulate, and dry to make black sea bream Finished snapper feed.
Embodiment 2
[0015] 20kg white fish meal, 40kg soybean protein concentrate, 25kg corn starch, 3.78kg fish oil, 5kg corn oil, 1kg sodium dihydrogen phosphate, 1kg compound vitamin, 1kg compound mineral, 3kg squid paste, 0.02kg phytase, 0.1kg compound Amino acids are mixed into 100kg of dry feed for black sea bream, wherein the compound amino acids contain 0.03kg of lysine, 0.03kg of methionine, and 0.04kg of tyrosine; then add 20Kg of water, stir, granulate, and dry to make black sea bream Finished snapper feed.

Abstract
The invention provides a high carbohydrate feed for spagrus macrocephalus. The feed is prepared from, by weight, 10%-20% parts of fish meal, 40%-50% of soy protein concentrate, 25%-30% of corn starch, 3%-5% of fish oil, 3%-5% corn oil, 1% of sodium dihydrogen phosphate, 1% of multi-vitamins, 1% of multi-mineral, 3% of sleeve-fish paste, 0.02% of phytase adn 0.1%-0.3% of compound amino acid. The high carbohydrate feed for the spagrus macrocephalus is adopted for breeding production, and on the premise that healthy growth of the spagrus macrocephalus is not influenced, the purposes that by decreasing the quantity of protein, used for supplying energy, in the feed, the dosage of the protein is decreased, the breeding feed cost is reduced, and pollution caused by nitrogen excretion to breeding water is relieved can be achieved.
Description
technical field [0001] The invention belongs to the technical field of fish feed and relates to a high-carbohydrate black sea bream feed. Background technique [0002] Black sea bream (Acanthopagrus schlegelii) (common scientific name Sparus macrocephalus), belongs to the class of ray-finned fishes, the order of Perciformes, the family of breams, and the genus of bream. Black sea bream is a rare and valuable economic marine fish cultured in the southeast coast of my country and Japan, South Korea, Taiwan, Southeast Asia and other countries and regions. The adult fish has delicious meat and high nutritional value, and is welcomed by consumers at home and abroad. It is one of the most potential targets for intensive marine fish farming in the future. [0003] Carbohydrates are an important and cheap energy substance. Adding an appropriate amount of carbohydrates to the feed can not only promote the pelleting process of the feed, but also reduce the amount of feed protein used...
