Embodiment 1

[0049] The present embodiment specifically illustrates the pond polyculture method of the present invention.

[0050] An ecologically efficient multi-species pond polyculture method for Penaeus vannamei comprises the following steps:

[0051] (1) Clear pond disinfection

[0052] Thoroughly dry the pond until the cracks turn white, and use a bulldozer to push away the silt with a thickness of 10 cm on the surface. 10-15 days before seedling release, inject 10cm of water to clear the pond with tea seed cake (the concentration of tea seed cake is 30mL / L) to kill harmful organisms and pathogenic organisms (viruses, bacteria) and various parasites.

[0053] (2) Stocking of shrimp seedlings

[0054] In East China, in the first ten days of May, when the water temperature is stable above 18°C, seedlings of Penaeus vannamei are stocked at a density of 50,000 to 55,000 fish per mu, with a body length of 0.8 to 1 cm. The body surface of the shrimp is clean, the muscles are full, the ab...

Embodiment 2

[0084] This embodiment illustrates the technical effect of using the method of the present invention for polyculture in combination with a specific breeding process.

[0085] Implementation location: Penaeus vannamei farm of Neitang Branch of Aquaculture Farm Co., Ltd., Wuzhong District, Suzhou City.

[0086] Implementation scale: an area of ​​30 mu, with 3 ponds of 10 mu each, to carry out the demonstration of the polyculture model of Penaeus vannamei, Macrobrachium rosenbergii, yellow catfish and silver carp.

[0087] The water inlet of the pond is installed with a water inlet net; the water inlet net is a conical net, the net length is 5-10m, and the mesh is 80 mesh;

[0088] The area of ​​the pond is east-west, and the water depth is 1.5-2.0m; the slope of the pond is at an angle of 30-40 degrees to the horizontal line. An aerator is installed every 5 mu in the pond.

[0089] A 300m 2 To mark the thick pond, dig a ditch outside the small pond, bury the plastic film or p...

Embodiment 3

[0095] This embodiment illustrates the technical effect of using the method of the present invention for polyculture in combination with a specific breeding process.

[0096] Implementation location: Penaeus vannamei farm of Neitang Branch of Aquaculture Farm Co., Ltd., Wuzhong District, Suzhou City.

[0097] Implementation scale: an area of ​​20 mu, with 2 ponds of 10 mu each, to carry out the demonstration of the polyculture model of Penaeus vannamei, Macrobrachium rosenbergii, bearded catfish and silver carp.

[0098] The water inlet of the pond is installed with a water inlet net; the water inlet net is a conical net, the net length is 5-10m, and the mesh is 80 mesh;

[0099] The area of ​​the pond is east-west, and the water depth is 1.5-2.0m; the slope of the pond is at an angle of 30-40 degrees to the horizontal line. An aerator is installed every 5 mu in the pond.

[0100] A 300m 2 To mark the thick pond, dig a ditch outside the small pond, bury the plastic film or pl...

Abstract

The invention relates to a multi-species pond polyculture method of penaeus vannamei, adopting polyculture of penaeus vannamei and macrobrachium rosenbergii, pelteobagrus fulvidraco/ clarias fuscus and hypophthalmichthys molitrix, and provides a specific polyculture ratio and culture method. The multi-species pond polyculture method of the penaeus vannamei well solves problems that the penaeus vannamei is easy to be ill, mortality rate is high, and benefits are unstable, the multi-species polyculture can effectively utilize breeding space, the macrobrachium rosenbergii, the pelteobagrus fulvidraco and the clarias fuscus can eat weak and sick prawns, prawn diseases can effectively be controlled, the hypophthalmichthys molitrix can eat cyanobacteria to regulate water quality, input cost of bait is reduced, a self-purification ability of a water body is enhanced, and ecological benefits are remarkable. According to the multi-species pond polyculture method of the penaeus vannamei, the survival rate of the penaeus vannamei is high, the scale is large, the macrobrachium rosenbergii, the pelteobagrus fulvidraco/ the clarias fuscus with higher economic value are harvested, and economic benefits are considerable.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for rational nesting of Penaeus vannamei, Macrobrachium rosenbergii and carnivorous fish. Background technique [0002] Penaeus vannamei has been loved by people for its delicious meat, large size and rich in various nutrients necessary for the human body. In terms of artificial breeding, Penaeus vannamei is popular among shrimp farmers for its fast growth rate, short breeding cycle, and high input-output ratio. In 2015, the national freshwater aquaculture output reached 731,500 tons, and the output value exceeded 10 billion. It is currently one of the most important aquaculture aquatic products in China. However, with the continuous improvement of nursery technology and breeding technology, the breeding density is increasing, and the problems of diseases and environmental pollution are becoming more and more serious, resulting in unstable production of Penaeus vannamei and l...
