Special compound feed for breeding parent prawns of penaeus monodon and preparation method thereof

Abstract

The invention provides a special compound feed for breeding parent prawns of penaeus monodon. The feed comprises the following components in percentage by weight: 25%-40% of fish meal, 5%-9.5% of artemia powder, 3%-6% of enzymolysis fish soluble pulp powder, 3%-9% of schizochytrium limacinum powder, 1%-3% of kelp powder, 2%-8% of hermetia illucens powder, 2%-5% of shrimp shell powder, 6%-12% of mussel powder, 2%-5% of marine red yeast dry powder, 10%-15% of flour, 1.5%-3% of lysolecithin, 0.8%-1.4% of ARA purified oil, 1.5% of DHA purified oil, 1.5% of EPA purified oil, 3.1%-3.7% of stearic acid triglyceride, 1%-2% of fish oil, 1%-5% of monocalcium phosphate, 0.9%-1.22% of vitamin premix and 1.08%-1.4% of mineral premix. According to the special compound feed, the growth performance of the parent prawns of penaeus monodon in the breeding period is remarkably improved, gonad development of the penaeus monodon is promoted, and the egg laying amount, the egg laying rate, the continuous egg laying rate, the fertilized egg hatching rate, the metamorphosis rate and the egg diameter of the parent prawns are increased.

Description

technical field [0001] The invention belongs to the technical field of aquaculture feed and breeding, and in particular relates to a special compound feed for broodstock breeding of Penaeus monodon. Background technique [0002] Penaeus monodon, commonly known as Grass shrimp and Blacktiger shrimp, belongs to Arthropoda, Crustacea, Decapoda, Penaeidae ( Penaeidae), the genus Penaeus, is one of the four major marine cultured shrimps in my country. In the past ten years, its average annual output has been about 70,000 tons. The main production areas in my country are Guangdong, Zhejiang, Fujian and Hainan. Improving the reproductive performance of broodstock and cultivating high-quality seedlings is one of the key links for the prosperity and development of Penaeus monodon aquaculture. [0003] Nutrition is an important determinant of gonadal maturation and seedling quality in shrimp. Natural bait such as clamworm, oyster, squid, cuttlefish can promote the development and re...

Problems solved by technology

However, there are many problems in the application process of biological bait: parent shrimps are easily infected by pathogenic pathogens carried by them; Restricts breeding benefits; feeding biological bait easily spoils water quality, bringing control difficulties and potential risks to broodstock breeding
