Formula of juvenile Penaeus vannamei biofeed prepared from silkworm slag

Abstract

The invention discloses a formula of juvenile Penaeus vannamei biofeed prepared from silkworm slag, and belongs to the technical field of marine aquaculture. The biofeed is made from the following raw materials by weight: 30-40 parts of vinasse, 50-60 parts of silkworm residue, 10-20 parts of wheat bran and 0.1-0.3 part of EM bacteria. The formula uses vinasse, silkworm residue and wheat bran as raw materials, combines of animal and plant proteins, can improve the disease resistance of the juvenile Penaeus vannamei, increase the survival rate, while improving water quality and playing a role in fertilizing the pond.

Description

technical field [0001] The invention relates to the technical field of marine product cultivation, in particular to a formula of biological feed for juvenile vannamei shrimp prepared from silkworm dregs. Background technique [0002] The meat of Penaeus vannamei is delicious, the processed meat rate can be as high as 67%, and the suitable temperature range and salt range are also wide. It is an excellent desalinated cultured species. Penaeus vannamei grows fast and has strong disease resistance. The main breeding of shrimp species is beneficial to increase the income of sea dwellers, but the risk of farming is also relatively high. This is because during the breeding process of prawns, it is very easy to affect the growth of prawns due to the factors of the breeding environment, feeding feed and feeding methods, resulting in aquaculture. The cost is too high, especially in the cultivation of juvenile shrimp in the early stage, water quality is particularly important. Good wa...

[0002] The meat of Penaeus vannamei is delicious, the processed meat rate can be as high as 67%, and the suitable temperature range and salt range are also wide. It is an excellent desalinated cultured species. Penaeus vannamei grows fast and has strong disease resistance. The main breeding of shrimp species is beneficial to increase the income of sea dwellers, but the risk of farming is also relatively high. This is because during the breeding process of prawns, it is very easy to affect the growth of prawns due to the factors of the breeding environment, feeding feed and feeding methods, resulting in aquaculture. The cost is too high, especially in the cultivation of juvenile shrimp in the early stage, water quality is particularly important. Good water quality is more suitable for the growth of juvenile shrimp, but the feed residues fed are the biggest culprit affecting water quality. Therefore, it is necessary to develop a method that can improve water quality. The feed that can promote the growth of juvenile shrimp is an urgent problem to be solved at present
