Abstract

The invention relates to a live food for river crab seedling breeding and a preparation method thereof. The food is complete in nutrients, has basically balanced amino acid components in protein and can adapt to a breeding environment and biological habits of river crabs. According to the food, the content of the protein is relatively high, the content of crude protein can reach 38-40%, the micro-powder food has stable suspension property in water and can be directly absorbed and digested by river crab seedlings. The live food for the river crab seedlings is rich in multiple active probiotic strains, is very strong in vitality and strong in metabolism after being put into a water body, and can rapidly proliferate and generate a large number of extracellular enzymes; macromolecules, such asresidual food and fish and shrimp wastes in the water are degraded into micromolecules, such as organic acids and amino acids; and abundant nutrients are provided for reproduction of diatoms and plankton. Meanwhile, probiotics play roles in ammoniation, nitrification, vulcanization and nitrogen fixation, remove toxic substances, such as the amino acids, nitrites and hydrogen sulfide in the waterbody, reduce chemical oxygen demand and biological oxygen demand, indirectly increase the amount of dissolved oxygen and purify the water.

Description

technical field [0001] The invention relates to the preparation technology of river crab feed, in particular to biological bait for raising river crab seedlings and a preparation method thereof. Background technique [0002] The scientific name of river crab is Chinese mitten crab, also known as "crab" and "hair crab". It is a rare freshwater product with delicious taste, rich nutrition and high economic value. The carapace formed by the combination of the crab's head and chest is square and hard. There is a pair of eyes on the front of the body, and two pairs of very sharp crab teeth on the side. The first pair of appendages of the crab are called chelicerae, and the surface is covered with fluff; behind the chelicerae, there are 4 pairs of walking legs, with flat sides and longer; the abdominal limbs have degenerated. The male and female of the river crab can be distinguished from its abdomen: the abdomen of the female is round, and the abdomen of the male is triangular....
