Abstract

The invention relates to laminarin additive premix feed for pseudosciaena crocea and belongs to the field of aquatic feed. The feed contains 6-12% by weight of laminarin. Aimed at problems of low immunity, high morbidity, high death rate and the like in existing pseudosciaena crocea culture, a premix feed additive added with laminarin is provided, so that the immunity and disease resistance of the pseudosciaena crocea can be remarkably improved, the feed efficiency is improved, nitrogen and phosphorus emission in a culture process is reduced, water pollution is alleviated, the survival rate and growth speed of the pseudosciaena crocea are increased, the feed cost is reduced, and economic benefits are increased.

Description

technical field [0001] The invention belongs to the field of aquatic feed, and in particular relates to a laminarin polysaccharide additive premixed feed for large yellow croaker. Background technique [0002] large yellow croaker ( Pseudosciaena crocea ) is a famous sea fish with high economic value. In recent years, large yellow croaker aquaculture has developed rapidly in my country's coastal areas. Large yellow croaker has become the species with the largest scale and output of seawater cage culture in the country. It is one of the most unique and best-selling seawater fish in Fujian Province and even my country. . At present, my country has formed a large yellow croaker breeding industry with an annual breeding capacity of more than 1 billion fish, a breeding output of nearly 120,000 tons (2013), and an output value of more than 7 billion yuan. However, after the successful artificial breeding of large yellow croaker in my country, there are problems such as germplasm...
