Compound feed for shellfish

Abstract

The invention provides a compound feed for shellfish, comprises the follows components of: 30 to 70% of protein feed, 30 to 50% of energy feed, 0.1 to 9% of minerals, 0.001 to 0.01% of vitamin, 2 to 10% of complex bacillus preparation and homogeneous powder with the content of crude protein higher than 15%. The quality is stable even if the compound feed is stored at a dry and shade place, the operation of use methods is simple and convenient, and produced activity feed is rich in nutrition and can be quickly absorbed by the shellfish to promote the growth of the mollusks. Meanwhile, the invention can promote the growth of single-cell algae, provide rich feed for the mollusks, and reduce the pollution of the feed to the environment.

Description

technical field

[0001] The invention relates to a feed for shellfish, in particular to a compound feed for shellfish which utilizes protease and amylase secreted by secretase bacteria to enzymolyze protein and carbohydrates in protein feed and energy feed. Background technique

[0002] In recent years, due to the expansion of the area of ​​enclosure aquaculture in my country year by year, the benefit of coastal prawn aquaculture has declined, and the enclosure aquaculture shellfish has been developed on a large scale, especially the high density of shellfish such as clams, clams, meretrix meretrix, mussels, scallops and oysters. Intensive farming, the traditional method of using natural zooplankton and unicellular algae in seawater as basic bait can no longer meet the normal growth needs of shellfish. In order to promote the growth of shellfish, coastal farmers in my country use low-value fish and shrimp that have been minced or Without any treatment, it is directly put into t...
