Ecological feed for procambarus clarkii and production method thereof

Abstract

The invention relates to ecological feed for procambarus clarkii and a production method thereof. The feed comprises the following components in parts by weight: 3-5 parts of imported fish meal, 2-4 parts of meat and bone meal, 10-12 parts of puffed soybeans, 8-10 parts of fermented soybean meal, 6-8 parts of peanut meal, 4-6 parts of rapeseed meal, 8-10 parts of shrimp powder, 1-2 parts of squidpaste, 3-5 parts of scallop skirt powder, 1.0-2.0 parts of fish oil, 1-2 parts of soybean oil, 1-2 parts of soybean lecithin, 1-2 parts of corn oil, 0.2-0.4 part of cholesterol, 20-22 parts of flour,6-8 parts of corn flour, 5-7 parts of rice bran, 2-3 parts of algae powder, 0.2-0.5 part of choline, 0.5-1.0 part of multivitamins, 1.5-2 parts of calcium lactate, 0.5-1.0 part of composite mineral salt, 0.3-0.5 part of vitamin C phosphate and 0.1-0.2 part of gamma-aminobutyric acid. The protein level and the phosphorus content of the feed are reduced, the feed digesting and absorbing rate of theprocambarus clarkia is increased, and the concentrations of the total nitrogen and the total phosphorus in procambarus clarkia aquaculture water are significantly reduced.

Description

technical field [0001] The invention belongs to the field of shrimp feed, and relates to Procambarus clarkii, in particular to a Procambarus clarkii ecological feed and a production method thereof. Background technique [0002] Procambarus clarkii, also known as crayfish, is a freshwater economical shrimp that is widely welcomed by people because of its delicious meat. Because of its omnivorous nature, fast growth rate and strong adaptability, it forms an absolute competitive advantage in the local ecological environment. Under the condition of suitable temperature and sufficient bait supply, after more than 2 months of breeding, it can reach sexual maturity and reach the standard of commercial shrimp. Its feeding range includes aquatic plants, algae, aquatic insects, animal carcasses, etc. When food is scarce Also cannibalism. Crayfish has become an important economically farmed species in China in recent years. [0003] However, in the process of high-density industrial...

Problems solved by technology

[0003] However, in the process of high-density industrialized shrimp farming, the protein and phosphorus content in the breeding feed is high, and the digestive system of the crayfish itself is not perfect, resulting in a low digestion and absorption rate of the feed, resulting in the discharge of undigested nitrogen and phosphorus to the The addition of residual bait in the water body will aggravate the pollution of the surrounding environment, which is not conducive to the sustainable cultivation of Procambarus clarkii
