Feed for Penaeus vannamei Boone in mature period and preparation method of feed

Abstract

The invention relates to feed for Penaeus vannamei Boone in the mature period and a preparation method of the feed. The feed comprises 25-30 parts of white fish meal, 5-10 parts of domestic fish meal, 2-5 parts of artemia dry powder, 2-5 parts of blood worm powder, 2-5 parts of earthworm powder, 10-15 parts of vital gluten, 2-5 parts of sunflower seed meal, 5-10 parts of carrot dry powder, 5-10 parts of ulva powder, 10-15 parts of haematococcus pluvialis powder, 2-5 parts of chlorella pyrenoidosa powder, 2-5 parts of cylindrotheca powder, 2-5 parts of diatom powder, 5-10 parts of cod liver oil, 2-5 parts of sea buckthorn seed oil, 0.002-0.005 part of photosynthetic bacterium, 0.002-0.005 part of bacillus subtilis and 0.01-0.05 part of composite multi-vitamin mineral. The feed has the advantages that the feed scientifically combines animal-source and plant-source feed raw materials according to the ingestion features of the Penaeus vannamei Boone and can provide sufficient nutrition for the Penaeus vannamei Boone, increase the disease resistance of the Penaeus vannamei Boone and promote molting and growth.

Description

technical field [0001] The invention belongs to the technical field of aquatic feed, and in particular relates to a mature stage feed of Penaeus vannamei and a preparation method thereof. Background technique [0002] Penaeus vannamei is one of the shrimps with the highest farming output in the world. After being introduced and cultured from the Pacific coast of South America in my country, especially after breaking through the nursery barrier in 1992, it was quickly promoted in my country's coastal areas and became one of the main cultured shrimps in my country. It provides high-quality protein food for fishermen to increase production and income and enrich consumers' tables. [0003] Penaeus vannamei has high nutritional value, delicious meat, and a meat yield as high as 67%. It is a rare cultured species. Compared with other shrimp species, Penaeus vannamei has a variety of food habits, strong disease resistance, fast growth rate, high breeding success rate, and low requi...

Problems solved by technology

[0004] However, the feed for each stage of Penaeus vannamei is immature, and there is room for improvement

Moreover, some feeds are lagging behind in nutritional research, and the simple ratio cannot fully meet the needs of Penaeus vannamei at each stage. In particular, the composition of some minerals and vitamins is not reasonable and needs to be improved.

The selection of feed ingredients related to each stage of Penaeus vannamei is unscientific, which affects the growth and molting of the shrimp body at different stages, and the breeding efficiency is unsatisfactory
