Procambarus clarkii feed and preparation method therefor

Abstract

The invention discloses a procambarus clarkii feed and a preparation method therefor. The feed comprises 8-12 parts of meat and bone meal, 12-18 parts of soybean meal, 0.2-0.6 parts of beer yeasts, 6-10 parts of cottonseed meal, 22-28 parts of corn flour, 20-25 parts of housefly larvae powder, 0.8-1.2 parts of bacillus subtilis, 1-1.5 parts of zinc sulfate, and 2-3 parts of calcium phosphate. The preparation method for the feed comprises steps of mixing, crushing, fermentation, drying and addition of funguses and minerals. The procambarus clarkii feed is advantaged by high utilization rate and low incidence of disease.

Description

technical field [0001] The invention relates to a feed for aquaculture and a preparation method of the feed, in particular to a feed for Procambarus clarkii and a preparation method thereof. Background technique [0002] Procambarus clarkii, commonly known as red crayfish and crayfish, belongs to the genus Procambarus genus of the family Crawfishidae of the order Decapod, Crustacea. Procambarus clarkii is native to North America and has now spread to most parts of my country. In recent years, with the growing demand for crayfish in the catering industry, the scale of artificial crayfish farming has also continued to expand. The existing feed of Procambarus clarkii is mostly replaced by feed such as prawns, giant river prawns or river crabs. Because the food composition of Procambarus clarkii is very wide, it usually includes organic debris, algae, aquatic plants, fish And fish eggs tend to be herbivorous and omnivorous, and the utilization rate after the above-mentioned exi...

Problems solved by technology

The existing feed of Procambarus clarkii is mostly replaced by feed such as prawns, giant river prawns or river crabs. Because the food composition of Procambarus clarkii is very wide, it usually includes organic debris, algae, aquatic plants, fish And fish eggs tend to be herbivorous and omnivorous, and the utilization rate of the above-mentioned existing feed after feeding is not high, causing a certain waste

However, it is inconvenient to collect and store the biological feed, and the ratio between the components is not easy to control. It is difficult to meet the needs of large-scale artificial breeding and accurate feeding. Moreover, the biological feed is likely to be mixed with bacteria, which will cause the disease of Procambarus clarkii and the breeding effect is not good. too ideal
