Compound feed for jade perch and spot fish cultivation and preparation method thereof

Abstract

The invention discloses a compound feed for the breeding of gemstone perch and spotfish and a preparation method thereof. The compound feed contains fish meal, insect fermented protein, soybean meal, fermented cotton meal, fermented rapeseed meal, enzymatically hydrolyzed soybean protein, and corn Distiller's grain protein, rice bran, subflour, flour, soybean oil, zeolite powder, salt, calcium dihydrogen phosphate, choline chloride, glycine, alanine, betaine, DMPT, pine needle powder, hawthorn powder, L-carnitine, bile Acid, Yikang XP, curcumin, tea polyphenols, multivitamins, and multimineral salts; it is prepared through the steps of raw material crushing, gelatinization, granulation, and drying. The compound feed of the present invention improves the survival rate of gem perch and grouper, promotes their healthy breeding, improves the digestion and absorption and transformation of fat in fish, effectively prevents the occurrence of fatty liver, greatly reduces the accumulation of intestinal fat, and effectively improves the quality of gemstones. The accumulation of sea bass and grouper muscle increases the meat yield of finished gemstone sea bass and grouper, and improves the flavor.

Description

technical field [0001] The invention relates to a fish feed, in particular to a compound feed used for cultivating gem perch and spot fish and a preparation method thereof. Background technique [0002] Scortum barcoo (Scortum barcoo) scientific name is high-body leatherfish, also known as jewel fish, jewel grouper, jewel spot, belongs to Perciformes, Percoidei, Teraponidae, Scortum ). Gem perch is native to the freshwater waters of Australia, and is a well-known freshwater fish in the country. Its meat is delicate, with few spines, and delicious and refreshing. It is the first choice for healthy and delicious food, and is favored by consumers. At the 2001 China International Fisheries Expo held in Qingdao, Shandong, promoted by the China Aquatic Products Circulation and Processing Association, Qingdao Chenhua Seed Co., Ltd. introduced the first batch of fish species from Australia. After years of research and exploration, it finally broke through its artificial breeding. ...

Problems solved by technology

There have been some reports on the development and research of Australia gem perch feed in China, but there is a lack of systematic research, and there is no production and supply of special feed suitable for large-scale farming of gem perch in earthen ponds or industrialization and cage culture. The compound feed of other fish can be used to feed the gem perch. The quality of the farmed commercial fish is uneven, especially the high abdominal fat (the proportion accounts for ≥10% of the fish weight), which seriously affects the economic benefits of the farmers and fails to really develop the gem.
