Abstract

The invention belongs to the field of aquaculture or feed, relates to a aquaculture feed, and especially relates to an alga immunopotentiation compound feed for litopenaeus vannamei. The invention at first provides an immunity strengthening agent for litopenaeus vannamei feed, and the agent is obtained through enzymatic hydrolysis and fermentation of an alga composite. The alga composite is composed of following components in parts by dried weight: 40 to 50 parts of asparagus, 15 to 25 parts of enteromorpha, 10 to 20 parts of ulva lactuca, 5 to 15 parts of laver and 5 to 15 parts of undaria pinnatifida. The invention further prepares a compound feed for litopenaeus vannamei by utilizing the immunity strengthening agent. The alga immunity strengthening agent contains algae polysaccharide, which has the effect of strengthening animal immunity, acrylic acid, terpenes, brominated phenolic and some sulfocompounds, which have the antiseptic effect, and sulphated polysaccharide, which has the antivirus effect. The litopenaeus vannameis fed on the alga immunopotentiation compound feed have a strong anti-stress performance, the body's immunity ability is improved, survival rate is high and culture benefit is remarkable.

Description

technical field [0001] The invention belongs to the field of aquaculture or feed, and relates to an aquaculture feed, in particular to a seaweed immune-enhancing type Penaeus vannamei compound feed. Background technique [0002] Shrimp is one of the most popular seafood products. Shrimp farming has brought good economic benefits to fish farmers. Penaeus vannamei has become a conventionally farmed species due to its fast growth, short breeding cycle and high population yield. [0003] In recent years, with the rapid increase of population and the large reduction of arable land, the shortage of feed has become a serious problem affecting the rapid development of the breeding industry, and the conflict between humans and animals competing for food has become more and more serious. Since seaweed is an autotrophic plant that can perform photosynthesis and convert inorganic substances in the ocean into organic substances, seaweed is a rich and low-cost feed resource for animals. ...
