Compound feed special for penaeus monodon breeding season nutrient enrichment and preparation method thereof

Abstract

The invention discloses compound feed special for penaeus monodon breeding season nutrient enrichment and a preparation method thereof. The compound feed comprises Peru fish powder, sleeve-fish meat powder, shrimp meat powder, pork liver powder and the like, can replace conventional fresh baits, solves the problems that source and quality of the fresh baits are unstable, also can promote gonad development of parental shrimps, and improves egg laying amount, egg hatchability and larva abnormal rate of penaeus monodon parental shrimps; spread of viral diseases among penaeus monodon is reduced, production of healthy penaeus monodon larvae is ensured, and stability of the compound feed under water is good, the compound feed is easy for the parental shrimps to absorb, water environment pollution in aquiculture areas is reduced, and therefore the compound feed has popularization and application value.

Description

technical field

[0001] The invention relates to the field of shrimp feed, in particular to a special compound feed for nutritional enhancement of Penaeus monodon during the breeding period and a preparation method thereof. Background technique

[0002] Penaeus monodon, commonly known as grass shrimp, has the characteristics of fast growth, miscellaneous food habits, wide-salinity, short breeding cycle, large individual, delicious meat, rich nutrition, and high yield of adult shrimp. It is one of the excellent varieties of shrimp farming in the world at present. First, its Asian production accounts for 91% of the world's total. In the late 1980s, after the successful artificial breeding of grass shrimp in southern my country, the breeding area expanded rapidly and the output was considerable. In recent years, grass shrimp has moved northward to the coastal farming of provinces such as Shandong, Hebei and Liaoning, and has gradually achieved success. With the rapid develop...
