Compound feed for improving blue bodies of penaeus vannamei boone under industrial culture and preparation method thereof

Abstract

The invention relates to a compound feed for improving blue bodies of penaeus vannamei boone under industrial culture and a preparation method of the compound feed. The compound feed comprises the following components in parts by weight: 15-25 parts of fish meal, 15-25 parts of mussel meat powder, 8-10 parts of scallop meat powder, 5-10 parts of chicken meal, 3-8 parts of shrimp shell powder, 3-8parts of crab shell powder, 5-8 parts of fermented soybean meal, 5-8 parts of fermented peanut meal, 2-4 parts of chironomid larva powder, 17-20 parts of wheat flour, 2-3 parts of cuttlefish paste, 2-3 parts of shrimp paste, 2-3 parts of hydrolyzed fish soluble, 1-3 parts of soybean lecithin oil, 1-2 parts of multi-vitamin multi-mineral premix, 0.2-0.5 part of spirulina powder and 2-5 parts of haematococcus pluvialis powder. The compound feed disclosed by the invention has a remarkable improvement effect on the blue body problem of the penaeus vannamei boone under industrial culture, and experiments prove that the feed disclosed by the invention can promote the immunity and growth of the penaeus vannamei boone on the basis of improving the blue body problem of the penaeus vannamei boone.

Description

technical field [0001] The invention relates to a compound feed for Penaeus vannamei, in particular to a compound feed for improving the blue body of Penaeus vannamei in an industrial culture mode and a preparation method thereof. Background technique [0002] Penaeus vannamei is an omnivorous cultured species with fast growth and strong stress resistance. It can grow at a temperature of 18-32°C and a salinity of 1-40‰. It is an excellent desalinated cultured species . [0003] At present, it has been widely cultivated in southern my country, but judging from the breeding situation in recent years, the breeding is often accompanied by the emergence of various diseases, which limits the success rate of the entire industry's breeding, so the cultivation of southern shrimp and northern shrimp has become a trend . [0004] Among the many white shrimp farming models in northern my country, the factory farming model is favored by farmers in northern my country because of its high...

Problems solved by technology

However, due to factors such as high breeding density, insufficient light or large-scale water changes, the lack of algae in the water body, and the decline in the physical fitness of prawns in industrial shrimp farming are prone to bluish shrimp in the later stage of farming, which will eventually affect the terminal price 1- 5 yuan / catties, which has a great impact on the benefits of farmers
