Anti-stress feed for culturing Penaeus vannamei Boone in greenhouse

Abstract

The invention relates to an anti-stress feed for culturing Penaeus vannamei Boone in a greenhouse. The anti-stress feed comprises 10-50% of fish meal, 5-10% of chicken powder, 3-10% of shrimp powder, 3-10% of a beer yeast, 10-30% of fermented soybean meal, 5-10% of squid powder, 10-16% of flour, 1-5% of fish oil, 1-3% of soybean phosphatide, 1-3% of betaine, 1-3% of a vitamin mixture, 2-4% of a mineral element mixture, 0.1-0.5% of Bacillus subtilis and 0.2-1% of taurine. According to the invention, the anti-stress feed selects feed raw materials having the advantages of high digestion and absorption utilization rate and strong food attraction against the growth and physiological digestion characteristics of the Penaeus vannamei Boone in the process of culturing in the greenhouse, trace nutritional elements comprising vitamins, mineral elements and the like needed by the healthy culture of the Penaeus vannamei Boone are reinforced, and simultaneously the Bacillus subtilis and the taurine are added, so shelling of the shrimps is promoted, the growth performances are improved, and the disease resistance and the stress resistance of the shrimps are enhanced. The mixed feed has the advantages of reliable sources of the raw materials, stable and safe quality, difficult water pollution, and suitableness for the large-scale culture of the Penaeus vannamei Boone in the greenhouse.

Description

technical field [0001] The invention relates to an anti-stress feed for growing Penaeus vannamei in greenhouses. technical background [0002] Currently, Penaeus vannamei (Penaeus vannamei Boone ) has been gradually promoted in the coastal farming areas of Jiangsu, Zhejiang and Shanghai. This model can effectively reduce large-scale disease outbreaks induced by environmental stresses such as typhoons and rainfall. At the same time, off-season farming can be carried out to improve farming efficiency. [0003] Nutritional preparation is a key technology in the cultivation of Penaeus vannamei in greenhouses, which directly affects the growth and survival rate of shrimp. Therefore, whether the nutritional preparation is reasonable or not will directly affect the breeding efficiency. At present, Penaeus vannamei culture in greenhouses mainly uses feed for Penaeus vannamei in outer ponds, which often leads to easy pollution of water quality and increases the probability of disea...

Problems solved by technology

The sheet-shaped prawn seed opening feed disclosed by this patent uses formula ingredients to replace part of the Artemia bait to reduce the production cost of shrimp seed cultivation, but this patent still retains 10-30% of the Artemia bait, although it is beneficial to seedling cultivation. The cost is acceptable, but if it is a large-scale greenhouse farming, obviously the cost still needs further consideration

In addition, for greenhouse culture, due to the limitation of the culture conditions, the water quality of the culture and the anti-stress performance of the shrimp still need to be further considered
