Problems solved by technology

At present, there are few researches on the special opening feed for duckbill sturgeon, and most of them use natural bait as the opening feed, which has the disadvantages of high cost, easy to pollute water quality, unstable quality, and easy introduction of pathogens such as parasites, bacteria and viruses.
Moreover, factors such as opening rules, nutritional requirements and feeding preferences of different fry were not considered.
The traditional duck-billed sturgeon nursery is affected by biological bait and training materials, the survival rate is only about 30-40%, and the fry cost is high

Abstract

The invention discloses special starter feed for polyodonspathala and a preparation method thereof. The feed is prepared from the following components in percentage by mass: 10-40 percent of fish meal, 10-30 percent of chicken meal, 3-10 percent of egg powder, 3-10 percent of beer yeast, 1-5 percent of wet sandworms, 10-30 percent of shrimp flesh, 10-15 percent of flour, 5-10 percent of soybean meal, 1-5 percent of fish oil, 1-3 percent of glycine betaine, 1-2 percent of vitamin mixture, 2-4 percent of mineral mixture and 1-2 percent of attractant. The special starter feed for polyodonspathalais developed for the special morpha and nutritional requirement of polyodonspathala, can meet the requirement of the polyodonspathala, and can be used for remarkably improving the survival rate. Thestarter feed breaks through the technical problem on traditional seedling, can solve the problems of transferring difficulty and low survival rate in production and reducing the cost for fries, and has good digestibility and absorbability, good suspension performance and good water resistance.

Description

technical field [0001] The invention belongs to the technical field of aquaculture. More specifically, it relates to a special opening feed for duckbill sturgeon and a preparation method thereof. Background technique [0002] Duck-billed sturgeon (scientific name, spoon-nose sturgeon) is a large-scale freshwater economic fish unique to the United States. It has been introduced into my country for trial breeding and has grown well. Duckbill, hence the name. The duck-billed sturgeon, like the Chinese sturgeon, is a rare fish in the world; it mainly feeds on earthworms, shrimps and plankton. It is native to the Mississippi River Basin in the United States and has lived on the earth since 300 million years ago (that is, the dinosaur period). A rare sturgeon that survived side by side is one of the only two species in the family Acipenseridae in the world. It belongs to the family Acipenseridae of Acipenseridae with the Chinese sturgeon and the white sturgeon in the waters of t...
