Problems solved by technology

When the salinity is higher than 26‰, because there is a large osmotic pressure gradient difference inside and outside the body, Penaeus vannamei needs to consume more energy to maintain its own osmotic balance, which will affect its growth to a certain extent
[0004] At the same time, under high salinity, the reproduction of harmful microorganisms such as Vibrio is very rapid, and the physique of Penaeus vannamei declines, and it is easy to get sick
At the same time, under the stress of high salinity, the feed intake of Penaeus vannamei slows down, causing some feed to be dissolved and lost in water, and the enzyme activity in the shrimp body decreases, which leads to an increase in the feed coefficient. Pollution is becoming more and more serious, which leads to frequent occurrence of diseases, which seriously plague the healthy development of the shrimp farming industry

Abstract

The invention belongs to the field of a feed, and relates to a prawn aquaculture compound feed. The feed comprises the following raw materials: 3-6 parts of euphausiid meal, 20-35 parts of fish meal, 2-4 parts of fly maggot meal, 3-7 parts of chicken meal, 1-5 parts of silkworm chrysalis meal, 2-6 parts of squid liver paste, 2-5 parts of shrimp shell meal, 1-3 parts of algae powder, 3-8 parts of fermented soybean meal, 3-13 parts of soybean meal, 3-8 parts of peanut meal, 2-7 parts of corn gluten meal, 10-20 parts of wheat flour, 4-10 parts of monosaccharide and / or oligosaccharide, 2-6 parts of sleeve fish liver meal, 2-4 parts of fish oil, 1-2 parts of soybean oil, 1-3 parts of soybean phospholipid powder, 0.1-0.4 part of choline chloride and 1-3 parts of monocalcium phosphate. The compound feed is capable of meeting the growth requirement of prawn for nutrition under high salinity (over 3%), good in stability in water, strong in anti-stress capability, high in survival rate and growth speed and low in feed coefficient.

Description

Technical field [0001] The invention belongs to the field of feed, and particularly relates to a special compound feed for shrimp aquaculture. Background technique [0002] In recent years, the cultivation area of ​​Penaeus vannamei in my country has rapidly expanded, and the total output and total benefits have also been greatly improved. In my country's Penaeus vannamei culture area, it is mainly divided into seawater high-salinity culture (such as Zhanjiang and Hainan in Guangdong), freshwater low-salinity culture (such as the Pearl River Delta in Guangdong) and brackish water culture regions. Under the scorching summer sun, as the water evaporates, the salinity will continue to rise, making the water environment change significantly, especially in Hainan. [0003] Shrimp's adaptation to the environment generally adjusts its osmotic pressure around its isotonic point, and osmotic pressure adjustment is a physiological process that requires energy. Penaeus vannamei is a wide-sa...
