Problems solved by technology

Penaeus vannamei has the advantages of large size, fast growth, low nutritional requirements, and strong disease resistance. It has strong adaptability to changes in water environment factors, low requirements for feed protein content, and long survival time out of water. It is an intensive The high-yield cultured fine species, Penaeus vannamei is the main breeding species of the company. The salinity control of pond water in the existing freshwater culture of Penaeus vannamei is unreasonable, which affects the survival rate. Improvement of culture method of white prawn

Embodiment 1

[0035] The hybrid ecological breeding method of Penaeus vannamei described in this embodiment is to cultivate Penaeus vannamei in the breeding pond and set up a fish pond next to the breeding pond to raise fish. The fish culture is 3 months earlier than the shrimp culture. It is characterized in that the cultivation of the vannamei shrimp includes the following steps:

[0036] A. Shrimp selection processing steps;

[0037] B. Steps of the first stage of shrimp larvae culture: cultured in the first stage for 10 days, the salinity of the pond water is controlled at 12‰ on the first day, and fresh water is added every day to reduce the salinity of the pond water every day, and the extent of the drop in the salinity of the pond water on the next day If it is greater than the previous day, the salinity of the pond water is finally maintained at 3‰. During this process, the number of feedings of the shrimp larvae per day generally shows a decreasing trend, and the amount of each feeding ...

Embodiment 2

[0044] The mixed ecological breeding method of Penaeus vannamei described in this example is different from Example 1 in that it adopts our company's special process parameter control, namely:

[0045] Step A includes the following measures: select healthy shrimp larvae of uniform size, full of vitality, and individual size of 0.55±0.1cm; put the shrimp larvae in the transport bag into the sieve and use the formalin solution Soak, the concentration of formalin solution is 200 ml / m3, and the soaking time is 30 seconds. After soaking, take it out and rinse with water.

[0046] Step B includes the following measures: the size of the first aquaculture pond used is 20 square meters, the pond depth is 1 meter, and the cement pond; the shrimp seedling process is: the water is disinfected and filtered and then injected into the first stage aquaculture pond , Add disodium ethylenediaminetetraacetate and methosulfon to the water, and oxygenate, adjust the salinity of the pool water to 12‰, t...

Embodiment 3

[0055] The mixed ecological breeding method of Penaeus vannamei described in this example differs from Example 1 in the use of feed (this improvement can also be applied to the breeding method of Example 2), that is: the method described in step B The feed composition used is: 55-75 parts of shrimp chips, 2-3 parts of broken yeast, 2-3 parts of marine red yeast, 0.1-0.5 parts of astaxanthin, 30.5-0.8 parts of vitamin D, soluble calcium salt 2- 4 parts, 3-5 parts of binder, 8-10 parts of disintegrant and 3-5 parts of moisture absorbent, all of which are parts by weight; the binder is hydroxypropyl methylcellulose or carboxymethyl Sodium cellulose; the disintegrant is sodium carboxymethyl starch, dry starch, or cross-linked polyvinylpyrrolidone; the hygroscopic agent is one of calcium oxide, magnesium oxide, aluminum oxide, and anhydrous copper sulfate Or several; broken yeast is rich in nucleotides, small nutrient peptides, glutathione, yeast cell wall polysaccharides and other ...

Abstract

The invention discloses a mixed ecological culture method of Penaeus vannamei Boone. In the method, Penaeus vannamei Boone is cultured in a culture pond and a fish culture pond is arranged beside the culture pond for culturing fish. The culture method of Penaeus vannamei Boone is characterized in that the method comprises the steps of A) Penaeus vannamei Boone larva selection and treatment; B) Penaeus vannamei Boone larva culture at a first stage: culturing the Penaeus vannamei Boone larvae for 10 days in the culture pond at the first stage, wherein the salinity of pond water on the first day is controlled to be 1.2 percent, fresh water is added every day thereafter to decrease the salinity of pond water every day, the decrease extent of the salinity of pond water on the day is higher than the decrease extent of the salinity of pond water on the day before and finally the salinity of pond water is kept at 0.3 percent; C) young Penaeus vannamei Boone culture at a second stage, wherein the salinity of pond water is controlled to be 0.2 percent; D) Penaeus vannamei Boone culture at a third stage, wherein the salinity of pond water is controlled to be 0.15 percent. Since the culture period of Penaeus vannamei Boone is divided into three stages of Penaeus vannamei Boone larvae, young Penaeus vannamei Boone and large Penaeus vannamei Boone and control of different salinities is adopted for each stage, more reasonable desalting culture is realized and the survival rate can be effectively improved.

Description

Technical field [0001] The invention relates to a method for aquaculture, in particular to a method for mixed ecological cultivation of Penaeus vannamei. Background technique [0002] Penaeus vannamei is one of the three largest shrimps with the highest aquaculture production in the world today. The meat quality of Penaeus vannamei is delicious, the processed meat rate can be as high as 67%, the suitable temperature range is wide, it can grow at 18-32℃, the salt range is also wide, and it can grow under the condition of salinity 1-40‰, which is an excellent The desalination of breeding species. Penaeus vannamei has the advantages of large individual size, fast growth, low nutritional requirements, strong disease resistance, strong adaptability to changes in water environmental factors, low feed protein content requirements, and long survival time out of water. It is intensive High-yield breeding of fine species, Penaeus vannamei is the company’s main breeding species. The curre...
