Soft feed for babylonia areolata parent mature stage and preparation method thereof

Abstract

The invention discloses soft feed for a babylonia areolata parent mature stage and a preparation method thereof. Base materials of the soft feed provided by the invention comprise white fish meal, a dried Acetes chinensis product, alpha-starch and kelp. The base materials also comprise additives of VC phosphate, VE, monocalcium phosphate, phosphatide, fish oil, feed micro-algae mud, beta-glucan and astaxanthin. The preparation method comprises the following steps of crushing the base materials of white fish meal, alpha-starch and kelp, mixing the powder obtained by the previous step and the dried Acetes chinensis product which is pressed into muddy flesh, adding the additives into the mixture obtained by the previous step, adding clean water into the mixture with the additives, uniformly stirring by an electric kneader, and carrying out extrusion granulation. The soft feed can provide nutrition components needed in a babylonia areolata parent mature stage, can realize a fast babyloniaareolata parent growth speed, wherein through the soft feed, a babylonia areolata parent growth period is in a range of 8 to 10 months, provides a good foundation for babylonia areolata parent sexualgland development and babylonia areolata parent fattening and ripening cultivation, has stable raw material sources and an appropriate price, can be prepared by the simple preparation method, and greatly reduces the pollution caused by residual feed on culture water, and babylonia areolata parent diseases.

Description

technical field [0001] The invention belongs to a mollusc bait for the parent snail growth period of Fangban Dongfeng snail and a production method thereof. Background technique [0002] At present, the parent snails of Fangban Dongfeng snails are collected from the natural sea area of ​​the South my country Sea or imported from Taiwan and Thailand. Its all-artificial breeding has been successful. Generally, parent snails are collected based on natural sea areas, and artificial breeding offspring is also used to produce parent snails. The sea area where Dongfeng snails are originally produced has clean water quality and rich bait, especially the sea area with reef bottom has always been an excellent growth area for original species of benthic organisms, which is conducive to the reproduction of Dongfeng snails. [0003] The life of Fangban Dongfeng snails goes through fertilized eggs, planktonic larvae, sessile young snails, snail seedlings with a body length of 0.6-0.8cm, ...
