Problems solved by technology

[0003] At present, the South American prawn feed has defects such as unbalanced nutrition, poor food attraction, and poor stability in water, which is not conducive to the feeding requirements of South American prawns, resulting in slow growth of South American prawns, weak disease resistance, low survival rate, and the preparation process. The feed atomized too quickly after entering the water, resulting in a decrease in the feeding rate of Penaeus vannamei

Abstract

The invention provides a preparation process of a penaeus vannamei seed culture feed, and relates to the technical field of penaeus vannamei seed culture. The preparation technology of the penaeus vannamei seed culture feed comprises the following steps: S1, preparing raw materials; s2, uniformly mixing the fish meal, the river snail powder, the river snail powder, the medical stone powder and the betaine, then adding the deionized water, and uniformly stirring to obtain a mixture A; s3, adding fermented peanut meal, yeast powder, photosynthetic bacteria, bacillus, brown sugar, choline chloride, beer yeast and bile salt into the mixture A, and uniformly stirring to obtain a mixture B; according to the invention, the feed raw materials with high utilization rate are selected to provide comprehensive and sufficient nutrition for penaeus vannamei boone, the disease-resistant additive can effectively reduce the morbidity of penaeus vannamei boone, improve the survival rate of culture, improve the activity and anti-stress ability of penaeus vannamei boone, and the corn starch paste is arranged to improve the coating ability of various components of the feed, so that the feed is more suitable for the breeding of penaeus vannamei boone. The feed is not easy to atomize after entering water, and the feeding rate of prawns is improved.

Description

technical field [0001] The invention relates to the technical field of Penaeus vannamei shrimp seedling cultivation, in particular to a preparation process of feed for Penaeus vannamei shrimp seedling cultivation. Background technique [0002] Penaeus vannamei belongs to the prawn family, and its scientific name is Litopenaeus vannamei. It is one of the three species with the highest production of farmed shrimp in the world. Penaeus vannamei has a thin shell and fat body, fresh and tender meat, with a meat yield as high as 65%, rich in nutrition, and is popular in domestic and foreign markets; the growth speed is fast, and it can reach the market specification in 60 days; the suitable salt range is wide (0-40% ), can adopt pure fresh water, brackish water, and seawater a variety of breeding modes, and can grow from natural sea areas to freshwater ponds, thus breaking the geographical restrictions, and has high temperature resistance and strong disease resistance. It is a hi...
