Abstract

The invention provides a biological agent for breeding seed shrimps and a preparation method thereof. The biological agent contains a composite yeast cake, and the composite yeast cake is prepared from the following raw materials in parts by weight: 10-20 parts of small shrimps, 5-10 parts of plant deadwood, 10-20 parts of algae extracting solution, 15-25 parts of polysaccharide, 1-5 parts of leavening agent and 10-20 parts of peanut meal powder. The biological agent prepared by the invention not only improves the immunity and the survival rate of seed shrimps, but also reduces the malformation rate of the seed shrimps, so that the mating rate of the seed shrimps is further improved, and meanwhile shrimp larvae obtained through incubation are high in immunity, good in stress resistance and rapid to grow.

Description

technical field [0001] The invention relates to the technical field of shrimp cultivation, in particular to a biological preparation for shrimp cultivation and a preparation method thereof. Background technique [0002] When the existing parental shrimps are bred and reserved, there is a lack of scientific and standardized means of feeding, resulting in a low survival rate of the parental shrimps, or insufficient nutrient intake leading to low immunity of the breeding shrimps. For example, CN202010035455.2 is a kind of shrimp maturation-promoting compound feed and its preparation method. The feed prepared by this invention is aimed at shrimp species. A compound microbial preparation for promoting the growth of shrimp seedlings is developed, and the invention prepares a biological preparation for improving the survival rate and immunity of seedling shrimp. Contents of the invention [0003] In view of this, the present invention proposes a biological agent for culturing sh...
