Problems solved by technology

[0003] At present, there are relatively few open baits for Penaeus vannamei shrimp juveniles in the market. Although there are small baits for juvenile shrimps on the market, the general particle size is too large and the nutrition is not balanced, which cannot meet the requirements of shrimp juveniles. Therefore, in order to improve The immunity and growth speed of prawns and shrimps provide a kind of bait for shrimps with balanced nutrition, good palatability and the effect of enhancing immunity

Abstract

The invention relates to an opening bait feed for shrimp fries and a preparation method of the opening bait feed. The opening bait feed for shrimp fries is prepared by processing the following raw materials in parts by weight: 20-30 parts of strong flour, 30-50 parts of fish meal, 5-10 parts of shrimp powder, 2-5 parts of meat and bone meal, 5-8 parts of soybean meal powder, 2-10 parts of rice bran protein, 3-5 parts of a glutathione-rich baker's yeast extract, 1-2 parts of a glutathione-rich selenium-rich yeast extract, 5-6 parts of glucan, 0.5-1.0 part of astaxanthin, 1-3 parts of soybean lecithin, 0.5-1 part of composite vitamins and 1-1.5 parts of complex mineral salt. According to the opening bait feed and the preparation method thereof disclosed by the invention, a reasonable enzymolysis technology is adopted, so that the obtained yeast powder is high in the content of total nitrogen and the content of amino-acid nitrogen, high in nutrient value, low in ash content and good in product quality; the yeast powder is used for the bait feed for the shrimp fries and good in palatability, the immunity of the shrimp fries can be enhanced, and the growth rate of the shrimp fries can be increased; the rice bran protein is high in nutrient value and good in palatability, when the rice bran protein is matched with other components for use, the shrimp fries can be promoted to eat, the immunity of the shrimp fries can be enhanced, and the growth rate of the shrimp fries can be increased.

Description

technical field [0001] The invention relates to an opening bait for shrimp seedlings and a preparation method thereof. Background technique [0002] Penaeus vannamei is one of the main cultured prawns in the world. However, with the continuous degradation of the environment and water quality, the cultivation of Penaeus vannamei is becoming more and more difficult, and the outbreak rate of diseases is getting higher and higher. The key is to have balanced nutrition in the seedling stage, which can improve the immunity of juvenile shrimp and avoid the occurrence of diseases. [0003] At present, there are relatively few open baits for Penaeus vannamei shrimp juveniles in the market. Although there are small baits for juvenile shrimps on the market, the general particle size is too large and the nutrition is not balanced, which cannot meet the requirements of shrimp juveniles. Therefore, in order to improve The immunity and growth speed of prawn larvae provide a bait for prawn...
