Abstract

The invention provides microbial fermentation feed for procambarus clarkia. The feed comprises the following components: soybean meal, bean dregs, vegetable cake, corn meal, fish meal, kelp meal, an attractant, a microbial strain and microelements, wherein the attractant contains betaine and squid visceral powder, the microbial strain includes at least one of bacillus subtilis and bacillus amyloliquefaciens and aspergillus niger, and the microelements include iron, manganese, zinc, silicon, cobalt and boron. The feed has a reasonable formula, is rich in various nutrient ingredients such as protein, amino acids, vitamins, minerals and unsaturated fatty acids, and can effectively meet the growth needs of the procambarus clarkia, and microorganisms in the feed can hydrolyze organic matter ina water body through the own metabolic activities, thereby achieving the purpose of purifying water.

Description

technical field [0001] The invention relates to the technical field of aquaculture feed, in particular to a crayfish microbial fermentation feed and a preparation method thereof. Background technique [0002] The scientific name of crayfish is Procambarus clarkii, also known as red crayfish or freshwater crayfish. It is shaped like a shrimp and has a hard carapace. It was introduced into my country in the late 1930s, and then quickly multiplied in the middle and lower reaches of the Yangtze River and became a common shrimp species. In recent years, crayfish has become an important economic breed in my country. With the increasing market demand, the stocking of crayfish in lakes can no longer meet the market demand, and artificial breeding has gradually become a trend. In artificial farming, crayfish feed is an extremely important part, which often limits the output of crayfish. Scientific and efficient feed formula has gradually become a key factor to improve the output of...
