Penaeus vannamei mid-stage aquaculture feed formula

Abstract

The invention discloses a penaeus vannamei mid-stage aquaculture feed formula and belongs to the technical field of seafood aquaculture. The penaeus vannamei mid-stage aquaculture feed is prepared from the following raw materials in parts by weight: 40-50 parts of silkworm residues, 10-20 parts of lees, 10-20 parts of fish meal, 10-20 parts of grain middling with rice-bran oil and 10-20 parts of edible starch; and medicinal effects of fructus momordicae and hawthorn fruits are further matched in the feed, so that the feed is capable of improving disease resistance of the penaeus vannamei in mid-stage. The penaeus vannamei mid-stage aquaculture feed has the effects of protecting the liver, promoting digestion and enhancing absorption, so that the feed is capable of promoting accelerated and stable growth of the penaeus vannamei.

Description

technical field [0001] The invention relates to the technical field of marine product cultivation, in particular to a feed formula for medium-term culture of Penaeus vannamei. 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. Mainly breed shrimp species, which is beneficial to increase the income of sea dwellers, but the risk of farming is also relatively large, because the shrimp is very susceptible to the factors of the breeding environment, feeding feed and feeding methods during the breeding process, especially in the mid-term breeding. The growth of prawns is the most unstable, and it is prone to pathological changes, does not eat, and grows slowly. Therefore, it is an urgent problem to be solved at present to develop a feed th...

It is an excellent desalinated cultured species. Penaeus vannamei grows fast and has strong disease resistance. Mainly breed shrimp species, which is beneficial to increase the income of sea dwellers, but the risk of farming is also relatively large, because the shrimp is very susceptible to the factors of the breeding environment, feeding feed and feeding methods during the breeding process, especially in the mid-term breeding. The growth of prawns is the most unstable, prone to pathological changes, no food, and slow growth. Therefore, it is an urgent problem to be solved at present to develop a feed that can promote the stable growth of prawns in the medium term, and has the effects of protecting the liver and digesting food.
