Problems solved by technology

The protein source of this invention is mainly fishmeal, which is highly dependent on external sources. Due to the influence of fishing ban and quota system in the source country of fishmeal, the supply is unstable and the price fluctuates greatly, which affects the processing of feed and the healthy development of the downstream aquaculture industry.
[0005] At present, there are relatively few open baits for Penaeus vannamei shrimp juveniles in the market. Although there are small sized baits for juvenile shrimp in the market, the particle size is generally too large and the nutrition is not balanced, which cannot meet the requirements of shrimp juveniles.

Abstract

The invention belongs to the technical field of feeds. The invention discloses a feed for litopenaeus vannamei seedlings and a preparation method. According to the preparation method, fish meal, euphausia superba powder, high-gluten flour, yeast powder, cuttlefish powder, fish oil, composite minerals, immune polysaccharides, meat and bone meal, gelatin, composite vitamins and glutathione-rich selenium-rich yeast extract are prepared into a starter feed by adopting a microcapsule technology. By adopting an advanced production process, the raw materials are fine in crushing granularity, are easily and quickly eaten by litopenaeus vannamei seedlings and are effectively digested, absorbed and utilized. The compound feed has good stability in the water, is more conducive to feeding of the seedlings, effectively reduces loss of nutrients, reduces eutrophication pollution to aquaculture water body, and is beneficial to healthy and rapid growth of the seedlings. The compound feed has reliablesource of raw materials, stable quality and low price, and effectively promotes sustainable development of shrimp industry.

Description

Technical field[0001]The invention relates to the technical field of feed, and more specifically to a vanilla shrimp seedling feed and a preparation method.Background technique[0002]Litopenaeus vannamei, the scientific name Litopenaeus vannamei, is native to the Americas and is one of the three main prawns in China and the world. However, in recent years, as the germplasm continues to degenerate and diseases continue to increase, the Farming is becoming more and more difficult. The high rate of disease outbreaks has also led to a continuous decline in yield per mu, and an increasing number of loss-making customers. Especially the EMS that has emerged in recent years is easy to break out within 15-40 days of breeding. The key reason is the broodstock germplasm. Poor, unbalanced nutrition in the shrimp seedling stage, resulting in low immunity of the larvae, and easy outbreak of EMS. The growth of shrimps comes from metamorphosis. The metamorphosis period is the critical period for sh...
