Special compound feed for industrial aquaculture of penaeus monodon

Abstract

The invention discloses a special compound feed for industrial aquaculture of penaeus monodon. The special compound feed comprises the following components in percentage by weight: 20%-25% of fish meal, 5%-8% of dephenolized cottonseed protein, 6%-10% of artemia powder, 6%-6.7% of degreased silkworm chrysalis meal, 6%-12% of scallop skirt powder, 3%-6% of enzymolysis fish soluble pulp powder, 1%-3% of dried porcine soluble powder, 2%-5% of superfine enteromorpha powder, 3%-6% of schizochytrium limacinum powder, 3%-6% of nannochloropsis oculata powder, 2%-5% of marine red yeast dry powder and the balance of water, 2%-3% of shrimp shell powder, 1%-3% of kelp powder, 7%-10% of flour, 3%-5% of peas, 1.5%-3% of lysolecithin, 1%-1.6% of fish oil, 0.2%-0.4% of taurine, 2%-3.5% of monocalcium phosphate, 0.8075%-1% of vitamin premix and 1.0925%-1.4% of mineral premix. The special compound feed for industrial aquaculture of the penaeus monodon is high in nutritional value, easy to digest, good in curing degree and high in stability, the growth performance, the anti-stress capability, the oxidation resistance and the body color of the penaeus monodon are remarkably improved, and nitrogen and phosphorus emission is reduced.

Description

technical field [0001] The invention belongs to the technical field of aquaculture feed, and more specifically relates to a special compound feed for the industrial culture of Penaeus monodon. Background technique [0002] Penaeus monodon, commonly known as Grass shrimp and Black tiger shrimp, is one of the four major marine cultured shrimps in my country. Penaeus monodon is more sensitive to changes in low water temperature and more resistant to high water temperature. Its suitable range is 17-35°C, and the optimum growth water temperature is 25-33°C. It stops feeding when the water temperature is lower than 18°C. Penaeus monodon is a euryhaline organism, and the suitable salinity range is 10-35‰. In the past ten years, its average annual output is about 70,000 tons. Guangdong, Zhejiang, Fujian and Hainan are the main producing areas of Penaeus monodon in my country. [0003] The factory farming model is a model of high-density intensive farming by investing in modern fac...

Problems solved by technology

However, at present, most factory farmers still have the habit of feeding fresh baits such as artemia, shrimp skin, and scallops. While increasing nutrition to promote growth, it also brings risks of water pollution and disease transmission; Farming is carried out indoors, lacking natural bait and sufficient light, and the breeding space is small. Therefore, industrialized shrimps often face a series of problems such as strong stress, slower growth than external pond culture, low feed utilization rate, and insufficient body color.

At present, there is still a lack of feed specifically for industrial farming of Penaeus monodon in the market. The development of high-nutrition, easy-to-digest, good stability, and low-pollution special feed for industrial farming of Penaeus monodon is an important way for the healthy and sustainable development of industrial farming. one
