Problems solved by technology

With the increase of the scale of shrimp and crab farming, there are many farming problems that need to be solved urgently, such as soft shell disease, failure to molt, hard shell, long moulting cycle, slow growth, high feed coefficient, etc.
Especially under the conditions of high-density breeding, the imbalance of feed nutrition, cannibalism and other factors are superimposed, which further reduces the survival rate in the process of shrimp and crab breeding, resulting in a decline in production and benefits

Abstract

The invention discloses a compound premix for promoting shrimp and crab molting. The compound premix comprises the following components in parts by weight: 0.1-0.5 part of a pearl cyanotis arachnoideaextract; 10 to 30 parts of vitamin premix; 40-60 parts of trace element premix; 1-3 parts of calcium gluconate; 1-20 parts of a calcium supplement; 1-20 parts of an immunopotentiator; and 5-10 partsof rice hull powder. The invention also discloses a preparation method and a feed of the compound premix for promoting shrimp and crab molting. By the adoption of the method, the requirements of shrimps and crabs for various nutrients in the shelling period are met, shelling of the shrimps and crabs is effectively promoted, the shelling period is shortened, and the growth speed and survival rate are increased.

Description
