Embodiment Construction

[0017] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0018] Such as Figure 1-3 Shown, a kind of high-density crab breeding pond, multi-channel soil ridge 4 is arranged in the pond 3, and the water area in the pond 3 is separated into continuous circulation water canal 5 by soil ridge 4, and underwater aeration canal is arranged in the circulation water canal 5 Aeration device 2, and the power that water circulation is provided by aeration device 2, soil ridge 4 is provided with gentle soil ridge slope, and the slope of soil ridge slope is not more than 1 / 3, can prevent crab from burrowing, and plant on the soil ridge slope Aquatic plants, aquatic plants are planted parallel to the direction of water flow, which is convenient for water circulation, and the flowing water env...

Abstract

The invention provides a high-density crab culture pond, aims to solve the problem of low density for crab culture in existing ponds, and relates to the technical field of aquaculture. A plurality of ridges are arranged in the pond to separate a water area in the pond into a continuous circular waterway, and an aerator is arranged at the bottom of the circular waterway and supplies power for water circulation. Compared with existing crab culture ponds, the crab culture pond has the advantages that the ridges are arranged in the pond, so that area suitable for crab culture in the pond is increased, and density for the crab culture in the pond is greatly increased by more than three times; the ridges separates the water area in the pond into the continuous waterway, so that water can flow, dissolved oxygen amount of the water can be increased and conditions for living habit of crabs can be satisfied; the ridges have small gradients, so that the crabs can be prevented from burrowing; the aerator aerates water underwater, so that the dissolved oxygen amount of the water can be increased and the water can be driven to flow.

Description

Technical field: [0001] The invention relates to the technical field of aquaculture, in particular to a high-density crab breeding pond. Background technique: [0002] Artificial breeding of crabs has very high requirements on the farms. At present, the ponds for cultivating crabs generally require an area of ​​1-5 mu. Crab ponds have sufficient water sources, good water quality, and easy access to water. The water depth is generally 1-1.5 meters. . The best quality of the bottom of the crab pond is sandy loam and gravel soil, with good ventilation performance, which is conducive to the growth and reproduction of aquatic plants, benthic animals and plants, and can provide natural feed for river crabs. The thickness of the mud at the bottom of the pond is generally not more than 5 cm. Anti-escape facilities, such as brick walls and plastic films, should be built around the crab pond. The water inlet and outlet of the crab pond should be blocked with barbed wire to prevent r...
