Problems solved by technology

With the rapid development of the aquaculture industry, the demand for fishmeal has risen sharply, and the price of fishmeal has continued to soar, which has increased the cost of feed manufacturers and aquaculture producers, seriously restricting the development of Litopenaeus vannamei aquaculture
[0004] In addition, due to the high nutritional requirements and low absorption capacity, only 70% of the fed protein can be absorbed in the culture process of Litopenaeus vannamei, and the rest that cannot be used exists in the culture water, resulting in excessive ammonia nitrogen discharge. Environmental pollution problems, therefore, low fishmeal feed is a major trend in the development of today's feed
[0005] In the existing low-fishmeal feed, plant-based protein raw materials are often used to replace fishmeal, which significantly reduces production costs. However, there are problems such as poor palatability, low feed utilization rate, slow growth rate of fed prawns, and poor disease resistance.

Embodiment approach

[0039] According to a preferred embodiment of the present invention, the protein source material includes fish meal and vegetable protein, and the vegetable protein is selected from peanut meal, soybean meal, rapeseed meal, gluten, soybean protein concentrate, cottonseed cake, One or more of corn gluten meal and wheat gluten.

[0040] Preferably, the vegetable protein is selected from one or more of peanut meal, soybean meal, rapeseed meal, gluten and soybean protein concentrate.

[0041] More preferably, the vegetable protein is peanut meal, soybean meal and gluten.

[0042] In a further preferred embodiment, the protein source material is composed of fish meal, peanut meal, soybean meal and gluten powder, and the weight ratio of each component is 22: (0.5-4): (10-18): (3- 8), preferably 22:(1-3):(12-16):(4-7), more preferably 22:(1.5-2.5):(13-15):(5-7).

[0043] In the present invention, plant source protein is used to replace part of the fishmeal, and the weight of each c...

Embodiment 1

[0196] Prepare basal feed:

[0197] (1) The raw material composition is as follows: every 100g dry weight feed includes 22g fish meal, 2g peanut meal, 14.04g soybean meal, 6.77g gluten powder, 2.36g fish oil, 0.31g soybean oil, 1.5g lecithin, 0.2g cholesterol, 20g high Gluten flour, 13.35g starch, 0.1g choline, 0.1gVC, 1.5g shrimp multidimensional, 1.5gCa(H 2 PO 4 ) 2 , 1.5g shrimp polymineral, 5g shrimp shell powder, 5g squid viscera powder, 0.05g ethoxyquinoline, 0.1g calcium propionate, 0.1g shelling protein, 2.5125g microcrystalline cellulose, 0.0075g pure GSH.

[0198] Among them, fish meal, shrimp shell powder, peanut meal, high-gluten flour, soybean meal, gluten powder, fish oil, soybean oil, and lecithin were purchased from Qingdao Qihao Biotechnology Co., Ltd.; Shrimp vitamin premix feed and shrimp microelement premix feed from Special Biotechnology Co., Ltd.; GSH pure product was purchased from Shandong Jincheng Biopharmaceutical Co., Ltd. (batch number B20150703)...

Embodiment 2

[0201] The method used in this example is similar to that of Example 1, except that the basic feed contains 2.505 g of microcrystalline cellulose and 0.015 g of pure GSH per 100 g of dry weight feed.

Abstract

The invention discloses a litopenaeus vannamei culture feed and culture method. The culture feed comprises a basic feed and an auxiliary feed, the basic feed reduces the content of fish meal, corresponding vegetable proteins are used for replacement, and a plurality of components (sugar source, fat source, vitamin, mineral substance and the like) are compounded, so that the production cost is reduced; and the auxiliary feed is added in different stages of vannamei culture, so that the adaptability of the feed to vannamei growth and development is improved. According to the litopenaeus vannameiculture method, according to the characteristics of the litopenaeus vannamei in different growth periods, different feeds are matched, oxygenation of different degrees is carried out, meanwhile, a water quality improver is periodically added to regulate and control a culture water body, so that the growth speed of the litopenaeus vannamei is remarkably increased, and the survival rate and the disease resistance are improved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a culture feed and a culture method of Litopenaeus vannamei. Background technique [0002] Litopenaeus vannamei, also known as Penaeus vannamei, Penaeus vannamei, Penaeus whiteleg, etc., is one of the world's three major economically farmed prawns. It can adopt various farming modes such as pure fresh water, brackish water, and sea water. China is Vanname The countries with the highest cultured area and output of Litopenaeus shrimp are mainly distributed in the southern coastal areas. [0003] Fish meal has the advantages of high protein content, rich in essential amino acids for animals, and can be digested and absorbed by animals. It has always been an indispensable high-quality protein source in aquatic feed, especially carnivorous aquatic animal feed. With the rapid development of the aquaculture industry, the demand for fishmeal has risen sharply, and the pr...
