Embodiment 1
[0033] The invention provides a method for ecological cultivation of Penaeus vannamei that improves cultivation efficiency, comprising the steps of:
[0034] 1) Select a culture pond and drain the water in the culture pond;
[0035] 2) Use a fence to form a circle around the breeding pond, and a ring formed outside the fence and the edge of the breeding pond is used as a sagittarius planting pond, and the middle part surrounded by the fence is used as a culture pond for Penaeus vannamei. The depth of cultivating pond, the area ratio of described Sagittarius planting pond and vannamei cultivating pond is 1:2-4, removes the silt of vannamei cultivating pond;
[0036] 3) lay a plurality of drainage pipes at the bottom of the Penaeus vannamei breeding pond, the nozzle of the drainage pipe is flush with the bottom of the pond, and the nozzle of the drainage pipe is provided with a filter screen to prevent the prawns from escaping;
[0037] 4) Introduce water into the culture pond,...
Embodiment 2
[0048] On the basis of Embodiment 1, a filter screen is also provided at the water inlet of the culture pond to prevent miscellaneous fish and shrimp from entering the culture pond, which will affect the cultivation of Penaeus vannamei.
Embodiment 3
[0050] On the basis of Example 2, at least two aerators are set in the culture pond to increase the dissolved oxygen in the water body and improve the survival rate and output of Penaeus vannamei.
[0051] In order to illustrate the beneficial effects of the present invention's cultivation, the applicant of the present invention has chosen 4 ponds of 8-10 mu (hereinafter referred to as pond 1, pond 2, pond 3 and pond 4) to cultivate with the method for the embodiment of the present invention 3, this The inventor has also selected 4 ponds of 6-8 mu (hereinafter referred to as pond 5, pond 6, pond 7 and pond 8) to cultivate with traditional methods, and the cultivation time is identical to draw the data as table 1:
[0052] Table 1
[0053]
[0054]
[0055] As can be seen from Table 1, the yield per mu of prawns in pond 1, pond 2, pond 3 and pond 4 is obviously higher than that of pond 5, pond 6, pond 7 and pond 8, which illustrates that the cultivation method of the pres...

Abstract
The invention discloses a penaeus vannamei ecological culture method for improving the culture efficiency. The method comprises the following steps that a culture pool is selected; water is thoroughly discharged; a sagittaria sagittifolia planting pool is selected on the periphery in the culture pool; a middle part is used as the penaeus vannamei culture pool; sludge in the penaeus vannamei culture pool is cleared way; a plurality of water discharge pipes are laid on the pool bottom of the penaeus vannamei culture pool; water is introduced for soaking sterilization; the water is thoroughly discharged; sagittaria sagittifolia is planted in the sagittaria sagittifolia planting pool; a plurality of pollution suction devices are arranged in the penaeus vannamei culture pool; water is introduced; the pH value of the water is regulated; fertilization is performed; a mixture of straws, chicken manure and cow manure is applied in the sagittaria sagittifolia planting pool for culturing planktonts; shrimp fries and feed are fed; the pollution suction devices are turned on for pollution suction every 10 to 15 days; then, the water discharge pipes are opened for pollution discharge. The penaeus vannamei ecological culture method has the advantages that the growth of the sagittaria sagittifolia can be promoted; the damage to the water quality in the penaeus vannamei culture pool can be prevented; the planktonts cultured in the sagittaria sagittifolia culture pool is food of the sagittaria sagittifolia; the growth of the sagittaria sagittifolia can be promoted; the culture of the planktonts and the culture of the sagittaria sagittifolia have complementary relation.
Description
technical field [0001] The invention relates to the field of aquaculture. More specifically, the present invention relates to a method for ecological cultivation of Penaeus vannamei that improves cultivation efficiency. Background technique [0002] As a kind of high-yield shrimp, Penaeus vannamei has been widely cultivated due to its high economic value. At present, the culture method of Penaeus vannamei is relatively common in small-scale high-density aquaculture. This method has a high density of seedlings. During the breeding process, due to the increasing amount of bait, the excrement and residual bait of the prawns accumulate more and more. These The excrement and residual bait will be fermented at the bottom of the water, and the protein content in the residual bait is high, which will seriously damage the balance of nitrogen, phosphorus and potassium elements in the water body, severely damage the ecological environment of the shrimp pond, and also damage the water ...
