Problems solved by technology

At present, general aquaculture adopts specific farming in specific areas. Generally, only one species can be cultured in one breeding site. In this way, in actual farming operations, the cost of investment is relatively high, and at the same time, the management is relatively cumbersome. The polyculture technology of aquatic products is basically still a blank

Embodiment 1

[0026] The ecological polyculture method of crab, soft-shelled turtle, freshwater shrimp and mandarin fish comprises the following steps:

[0027] (1), Pond conditions and supporting facilities:

[0028] ① Pond conditions: The pond requires a quiet environment, sufficient sunlight, abundant water source, fresh water quality, convenient drainage and irrigation, an area of ​​20 acres, an average water depth of 1.5 meters, and a deep water area and a shallow water area. The seedlings need to be dredged, sun-dried and disinfected before stocking.

[0029] ②Water system matching: water inlet and outlet are set at both ends of the pond, the water inlet is set on the highest water level interface, and cement culvert pipes are used to extend into the pool, and the water outlet is set on the opposite side of the water inlet. Both the water inlet and outlet are sealed with barbed wire, and the water inlet is covered with a pipe bag made of silk screen.

[0030] ③. Construction of the ...

Embodiment 2

[0044] The ecological polyculture method for crabs, soft-shelled turtles, freshwater shrimps and mandarin fish is characterized in that it comprises the following steps:

[0045] (1), Pond conditions and supporting facilities:

[0046] ① Pond conditions: The pond requires a quiet environment, sufficient sunlight, abundant water source, fresh water quality, convenient drainage and irrigation, an area of ​​10 mu, an average water depth of 2 meters, and a deep water area and a shallow water area. The seedlings need to be dredged, sun-dried and disinfected before stocking.

[0047] ②. Supporting water system: water inlet and outlet are set at both ends of the pond, the water inlet is set on the highest water level interface, and cement culvert pipes are used to extend into the pool, and the water outlet is set on the opposite side of the water inlet. Both the water inlet and outlet are sealed with barbed wire, and the water inlet is covered with a pipe bag made of silk screen.

Abstract

The invention provides a method for ecological polyculture of crabs, soft-shelled turtles, freshwater shrimps and mandarin fish and relates to the technical field of aquaculture. The method comprises the steps of pond condition and supporting facility and cultivation management. The method has the advantages that production resources are fully utilized, professional devices are not needed, the method is free of culture pollution, a cultivation technology is standard, the feeding is scientific and normative, a polyculture technology is novel, aquaculture quality is greatly improved, and accordingly the earnings are increased.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an ecological polyculture method for crabs, soft-shelled turtles, freshwater shrimps and mandarin fish. Background technique [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding management. In a broad sense, it can also include the proliferation of aquatic resources. Aquaculture includes extensive culture, intensive culture and high-density intensive culture. Extensive culture is to put seedlings in small and medium-sized natural waters, and to grow aquatic products completely by natural bait, such as fish culture in lakes and reservoirs and shellfish culture in shallow seas. Intensive farming is the use of bait and fertilization methods to grow aquatic products in smaller water bodie...
