Functional feed for breeding micropterus salmoides and breeding method thereof

Abstract

The invention provides a functional feed for breeding micropterus salmoides. The functional feed for breeding the micropterus salmoides comprises expanded feed for preventing liver and gall syndromes, wherein the expanded feed for preventing the liver and gall syndromes comprises the following components of fish meal, methane mycoprotein, bone collagen protein powder, soybean protein concentrate powder, a starch mixture, an amino acid mixture, a mineral premix, a vitamin premix and a compound glycolipid metabolism activator. The method for breeding the micropterus salmoides by using the functional feed for breeding the micropterus salmoides comprises the following steps of (1) maintaining the stability of a water breeding environment in a breeding pond; (2) controlling selection and throwing of fry of the micropterus salmoides; (3) controlling the feeding frequency and the feeding amount; and (4) arranging a solar energy aerator and a bio-floating bed. The functional feed for breeding the micropterus salmoides has the advantages that the liver and gall syndromes of micropterus salmoides breeding can be prevented, and the breeding survival rate of the micropterus salmoides is increased.

Description

technical field [0001] The invention relates to a functional feed for breeding California perch and a breeding method thereof, belonging to the technical field of breeding. Background technique [0002] According to the 2020 Fisheries Yearbook statistics, the national California perch production in 2019 was 498,000 tons, an increase of about 10.59% compared with 2018, and the growth rate in 2020 was about 20%. The production of perch is about 600,000 tons; therefore, according to the current growth rate, California perch will become one of the important farmed species of million tons. [0003] However, in recent years, with the continuous expansion of the production and scale of California sea bass farming, the most troublesome thing in the process of California sea bass farming is liver and gallbladder disease. The key mechanism of sea bass growth is the obstruction of liver metabolism. There are two types of "mainly fat in liver cells" and "mainly fat in liver cells", whi...

[0003] However, in recent years, with the continuous expansion of the production and scale of California sea bass farming, the most troublesome thing in the process of California sea bass farming is liver and gallbladder disease. The key mechanism of sea bass growth is the obstruction of liver metabolism. There are two types of "mainly fat in liver cells" and "mainly fat in liver cells", while California sea bass is not only a congenital "fatty liver patient" (lack of anti-adipogenic factors in the liver), but also a congenital "diabetic patient" (resistance to sugar low capacity and low utilization rate of starch), so the maintenance of the liver is very important. Once the liver of the California perch suffers from pathological changes, it will cause the fish's immunity to decline, metabolic disorders, bait digestibility, and food intake to decrease. This state Baja perch is very susceptible to other pathogenic diseases (such as Nocard's disease, iridescent virus, etc.) and the mortality rate increases. Some ponds have a mortality rate as high as 50%, causing major economic losses to farmers
