Description

technical field [0001] The invention relates to a feed for Penaeus vannamei, in particular to an environment-friendly fishmeal-free feed for Penaeus vannamei, which belongs to the field of aquatic feed. Background technique [0002] Since the 90s of last century, Penaeus vannamei has become the largest prawn species in my country, accounting for 90% of the total shrimp production. %above. [0003] Because fishmeal has the characteristics of high content of essential amino acids and fatty acids, low carbohydrate content, good palatability, low anti-nutritional factors and good digestion and absorption by farmed animals, it has always been an indispensable high-quality aquafeed protein source. In prawn feed, the amount of fishmeal usually reaches 30-40%, which is the largest component of prawn feed cost. In recent years, affected by the decline of global fishery natural resources, the world's fish meal production has declined year by year, while the demand for fish meal has ...

[0006] At the same time, in order to further improve the economic benefits of farming, Penaeus vannamei adopts an intensive and high-density farming model, which is also very prone to stress (such as nutrition, crowding, environmental changes, etc.) Disturbance, decreased disease resistance, easy epidemics and outbreaks of diseases and other hazards. On the other hand, intensive and high-density farming models also cause the taste and color of vannamei to deteriorate, especially in pure freshwater farming. The flavor of prawns when eaten The color and color become lighter, the nutritional value decreases, and the price of the commodity is difficult to increase, which seriously affects the economic benefits of Penaeus vannamei farming
