Polyodonspathala fry feed for improving survival rate

Abstract

The invention provides a polyodonspathala fry feed for improving survival rate. The polyodonspathala fry feed comprises the following components in parts by weight: 40-60 parts of fish meal, 10-20 parts of freshwater shrimp meal, 5-15 parts of pig liver powder, 5-15 parts of kelp powder, 40-60 parts of soybean meal, 10-20 parts of sorghum flour, 10-20 parts of soybean flour, 10-20 parts of barley flour, 20-30 parts of cottonseed meal, 10-20 parts of rapeseed meal, 5-15 parts of bran, 5-15 parts of clamworm powder, 10-20 parts of wheat middling, 5-15 parts of alfalfa powder, 20-40 parts of phospholipids, 10-20 parts of seaweed powder, 4-6 parts of medical stone powder, 10-20 parts of vegetable oil and 1-3 parts of core additive, wherein each 100 parts of core additive is prepared from the following components in parts by weight: 20-30 parts of garlic, 20-30 parts of onion, 10-20 parts of shiitake, 10-20 parts of rhizoma acori graminei, 5-15 parts of echinacea and 5-15 parts of mulberry. The polyodonspathala fry feed provided by the invention can provide basic nutritious substances for the polyodonspathala fry, and the growth efficiency of the polyodonspathala fry is ensured. In addition, through optimization of the feed formula and addition of the core additive, the immunity of the polyodonspathala is improved. The polyodonspathala fry feed has the advantages of high safety, wide material source and low cost.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a feed for duck-billed sturgeon seedlings with improved survival rate. Background technique [0002] Duckbill sturgeon, scientific name American sturgeon. It mainly feeds on earthworms, shrimps and plankton. It is named because of its unique shape, long and flat snout, like a duckbill and paddle-like shape. The duck-billed sturgeon (Acipenser acipenser) is native to the Mississippi River Basin in the United States. It is a rare sturgeon that has lived on the earth 300 million years ago (that is, the dinosaur period). It is the only two species of Acipenser in the world. one of the species. It belongs to the family Acipenseridae of the order Acipenseridae, together with the Chinese sturgeon and the white sturgeon in the waters of the Yangtze River, and is one of the best fish among fishes. [0003] At present, there are several major problems in the breeding technology of...

Problems solved by technology

[0003] At present, there are several major problems in the breeding technology of duck-billed sturgeon seedlings: first, in the environment of mostly still water ponds in Peiyun, high-density breeding causes a large amount of aquatic animal excrement, residual bait, disinfectants, etc. Decomposition releases a large amount of harmful substances, which increases the density of aquaculture, degrades the water environment, and aquaculture diseases are also increasing. Many diseases have seriously threatened the efficiency of aquaculture.

However, the loss of feed in water and the accumulation of excreta have become the main pollution sources of water bodies, resulting in deterioration of water quality, large-scale reproduction of pathogens, decreased survival rate, increased dosage of medicines, frequent water changes, and increased breeding costs.
