Problems solved by technology

However, the application of compound feed to raise California perch is prone to the following problems: (1) California perch is less fond of compound feed than chilled bait; (2) California perch has a low utilization rate of carbohydrates, and the liver has poor tolerance to sugar, but is affected by Due to the limitation of domestic production equipment and technology, it is difficult to reduce the level of feed carbohydrates
In the above-mentioned California sea bass compound feed, long-term intake of this high-carbohydrate feed will lead to abnormal metabolism of the California sea bass liver, anorexia and other problems in the later stage

Abstract

The present invention discloses a starch-free starter compound feed for micropterus salmonides fries. The compound feed comprises the following components in percentages by mass: 55-65% of Peruvian steam fishmeal, 10-20% of soybean protein concentrate, 4-8% of pure kelp powder, 5-7% of a squid paste, 1-1.5% of soybean phospholipid oil, 3-6% of fish oil, 2-2.5% of calcium dihydrogen phosphate, 0.2-0.3% of lysine, 0.1-0.15% of methionine, 0.3-0.8% of choline chloride, 0.2-0.4% of compound multiple vitamin for micropterus salmonides and 1.6-1.8% of compound multiple minerals for the micropterus salmonides. The starter compound feed can meet long-term food intake, does not cause problems of abnormal liver metabolisms of fries, etc., and at the same time can significantly improve growth speed and survival rate of the fries.

Description

Technical field [0001] The invention relates to a compound feed for fish fry, in particular to a starch-free open compound feed for California sea bass fry, belonging to the technical field of aquatic animal feed. Background technique [0002] California bass, also known as largemouth bass, belongs to the Perciformes (Perciformes) Sunfish family (Centrarchidae). It is native to California, USA, and was introduced to China in the early 1980s. California sea bass has the advantages of fast growth, less disease, low temperature tolerance, more thorns, delicious taste, and rich nutrition, and is very popular in the market. In recent years, California bass has become one of the important freshwater cultured species in my country. [0003] California Bass has strong adaptability and is a kind of eurythermic carnivorous fish. It can survive the winter naturally in the south and north of my country, and can be cultured in most provinces in my country. In recent years, the amount of Calif...
