Description
Technical Field
The invention belongs to the technical field of aquaculture, and particularly relates to a litopenaeus vannamei breeding feed and a breeding method.
Background
The litopenaeus vannamei, also known as penaeus vannamei, white leg prawn and the like, is one of the three economic prawn cultures in the world, can adopt various culture modes of pure fresh water, brackish water, seawater and the like, China is the country with the highest culture area and yield of the litopenaeus vannamei, and the culture range is mainly distributed in the coastal areas of the south.
Fish meal has the advantages of high protein content, rich amino acids essential for animals, capability of being digested and absorbed by animals and the like, and is an indispensable high-quality protein source in aquatic feeds, particularly carnivorous aquatic animal feeds. With the rapid development of aquaculture industry, the demand of fish meal rapidly rises, and the price of the fish meal continuously rises rapidly, so that the cost of feed production enterprises and culture producers continuously increases, and the culture development of litopenaeus vannamei is severely restricted.
In addition, due to the high nutritional requirement and the low absorption capacity, only 70% of feeding protein can be absorbed in the breeding process of the litopenaeus vannamei, and the rest of the protein which cannot be utilized exists in a breeding water body, so that the problem of environmental pollution caused by overhigh ammonia nitrogen emission is caused, and therefore, the low-fish-meal feed is a great trend in the current feed development.
In the existing low fish meal feed, vegetable protein raw materials are mostly used for replacing fish meal, so that the production cost is obviously reduced, but the problems of poor palatability, low feed utilization rate, slow growth speed of fed prawns, poor disease resistance and the like exist.
Therefore, the breeding feed for the litopenaeus vannamei with low fish meal has the advantages of good palatability, low production cost, high utilization rate, high growth speed of fed prawns and strong disease resistance.
Disclosure of Invention
In order to overcome the problems, the inventor carries out intensive research and designs a culture feed and a culture method for the litopenaeus vannamei, the culture feed comprises a basic feed and an auxiliary feed, the basic feed reduces the content of fish meal and the production cost, and the glutathione auxiliary agent is added, so that the disease resistance, the survival rate and the like of the litopenaeus vannamei are obviously improved; the auxiliary feed comprises auxiliary feeds A and B, is applied by assisting the basic feed according to the characteristics of the prawns in different growth periods, and is beneficial to improving the intestinal health and the growth speed of the prawns; the culture method is characterized in that different feeds are matched according to the characteristics of prawns in different growth periods, oxygenation with different degrees is carried out, meanwhile, the water quality modifier is periodically added to regulate and control the culture water body, the growth speed of the prawns is obviously improved, and therefore the invention is completed.
Specifically, the present invention aims to provide the following:
in a first aspect, the feed for breeding litopenaeus vannamei comprises a basic feed and an auxiliary feed, wherein the basic feed is prepared from the following raw materials in parts by weight:
in a second aspect, a preparation method of a litopenaeus vannamei breeding feed is provided, and the method comprises the following steps:
step 1, preparing a basic feed;
step 2, preparing an auxiliary feed;
preferably, step 1 comprises the sub-steps of:
step 1-1, crushing raw materials;
step 1-2, mixing raw materials;
step 1-3, granulating;
and 1-4, drying.
In a third aspect, a method for breeding litopenaeus vannamei is provided, preferably, the breeding feed of the first aspect or the breeding feed prepared by the method of the second aspect is used for breeding, and the breeding method comprises the following steps:
step I, putting shrimp larvae;
step II, feeding breeding feed;
and step III, cultivation management.
The invention has the advantages that:
(1) the feed for breeding the litopenaeus vannamei provided by the invention has the advantages that the content of fish meal is reduced in the basic feed, the corresponding vegetable protein is adopted for substitution, and various components (a sugar source, a fat source, vitamins, mineral substances and the like) are compounded, so that the production cost is reduced, and the components are mutually matched and act synergistically, so that the nutritional ingredients of the feed are obviously improved;
(2) the glutathione auxiliary agent is added into the basic feed of the litopenaeus vannamei breeding feed, so that the basic feed obviously improves the growth effect, feed utilization, immune reaction, intestinal tissue shape and disease resistance of the litopenaeus vannamei;
(3) according to the litopenaeus vannamei breeding feed, different types of auxiliary feeds are added at different stages of the litopenaeus vannamei breeding, so that the adaptability of the feed to the growth and development of the litopenaeus vannamei is improved, the disease resistance of the litopenaeus vannamei is enhanced, and the survival rate and the growth speed are improved;
(4) according to the method for culturing the litopenaeus vannamei, different feeds are matched according to the characteristics of the litopenaeus vannamei in different growth periods, oxygenation is carried out in different degrees, meanwhile, the water quality modifier is periodically added to regulate and control the culture water body, the growth speed of the litopenaeus vannamei is obviously improved, the survival rate and the disease resistance are improved, and the intestinal health is facilitated.
