Special ecological feed for penaeus vannamei in intensive culture shrimp pond

Abstract

The invention belongs to the field of feeds, and particularly relates to a special ecological feed for penaeus vannamei in an intensive culture shrimp pond. The special ecological feed comprises the following components in parts by mass of protein raw materials of 12 parts of fish meal, 18 parts of puffed soybeans, 10 parts of fermented soybean meal, 12 parts of peanut meal, 8 parts of rapeseed meal, 9 parts of shrimp powder and 3 parts of scallop skirt powder, fat raw materials of 1.5 parts of fish oil, 1.5 parts of soybean oil, 2.5 parts of soybean lecithin, 1.5 parts of corn oil and 0.3 part of cholesterol, carbohydrate raw materials of 20 parts of flour and 7 parts of corn flour, and other additives: 2 parts of dried marine algae powder, 0.3 part of choline, 0.8 part of composite vitamins, 1.5 parts of calcium dihydrogen phosphate, 0.8 part of complex mineral salts, 0.15 part of vitamin C phosphate ester and 0.15 part of gamma-aminobutyric acid. According to the special ecologicalfeed, the protein level and the content of phosphorus in the feed can be reduced, and the pollution pressure on environment on the periphery is alleviated.

Description

technical field [0001] The invention belongs to the field of feed, in particular to a special ecological feed for Penaeus vannamei in intensive shrimp ponds. Background technique [0002] Penaeus vannamei is one of the three largest shrimp species with the highest aquaculture production in the world today. The meat of Penaeus vannamei is delicious, the processed meat rate can be as high as 67%, the suitable temperature range is wide, it can grow at 18-32 ℃, and the salt range is also wide, and it can grow under the condition of salinity 1-40‰. desalinated cultured species. Penaeus vannamei grows fast and has strong disease resistance. It has gradually become the main cultured shrimp species in southern my country. [0003] However, in the process of high-density industrialized shrimp farming, the protein and phosphorus content in the breeding feed is high, and the digestive system of the shrimp itself is not perfect, resulting in a low digestion and absorption rate of the ...

Problems solved by technology

[0003] However, in the process of high-density industrialized shrimp farming, the protein and phosphorus content in the breeding feed is high, and the digestive system of the shrimp itself is not perfect, resulting in a low digestion and absorption rate of the feed, resulting in the discharge of undigested nitrogen and phosphorus into the water body In addition, the addition of residual bait will aggravate the pollution of the surrounding environment, which is not conducive to the sustainable cultivation of Penaeus vannamei
