Penaeus vannamei larva feed and method for preparing same

Abstract

Provided are Penaeus vannamei larva feed and a method for preparing the same.The feed is made from: 20-25 parts of white fishmeal, 10-15 parts of brown fishmeal, 5-10 parts of Artemia dry powder, 2-5 parts of bloodworm powder, 5-10 parts of wheat gluten flour, 2-5 parts of potato meal, 2-5 parts of raspberry powder, 10-15 parts of Sargassum thunbergii powder, 5-10 parts of Haematococcus pluvialis powder, 2-5 parts of Spirulina powder, 5-10 parts of Cylindrotheca powder, 2-5 parts of Chaetoceros muelleri powder, 5-10 parts of Schizochytrium oil, 2-5 parts of sea buckthorn seed oil, 0.002-0.005 part of Bifidobacterium, 0.002-0.005 part of Bacillus subtilis, and 0.01-05 part of compound multi-vitamin mineral.Animal and plant feed materials and the compound multi-vitamin mineral are added, the feeding characteristics and nutrition needs of shrimp larvae are met, growth and successful shelling are facilitated, immunity is improved, and survival rate is increased.

Description

technical field [0001] The invention belongs to the technical field of aquatic feed, and in particular relates to a feed for young 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 in 1992, it broke through the nursery barrier and was quickly promoted in my country's coastal areas, becoming 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 requirements for ...

Problems solved by technology

[0004] However, although progress has been made in nutritional and physiological research on the juvenile stage of Penaeus vannamei, it has not been reflected in the research and development of feed in a timely manner. In the first place, some farming enterprises do not feed bait at the stage of shrimp fry

In this way, the method of using natural food as bait or fertilizer and water will introduce diseases to the cultivation of shrimp seedlings. The shrimp seedlings themselves will also have problems of insufficient vitamins and minerals, which will affect their growth and development. The growth rate of shrimp seedlings is slow and survival rate is not high
