Pond ecological breeding system for river crabs in southern areas

Abstract

The invention discloses a pond ecological breeding system for river crabs in southern areas. The pond ecological breeding system comprises a pond body, sandbag modules, a cage body, a drainage ditch and a plurality of planting frames; the sandbag modules are laid at the bottom of the pond body and are arranged in rows and columns, interval lanes are formed between the adjacent rows and columns, and fine sand is laid in the interval lanes; the cage body is laid along the interval lanes, a mud pumping pipeline is laid along the interior of the cage body, a mud suction opening is formed in the mud pumping pipeline, and an anti-escape net is arranged outside the cage body in a covering manner; the drainage ditch is arranged along one side of the pond body, and a water level adjusting pipe is arranged in the drainage ditch; and the planting frames are arranged in the pond body, a plurality of rows of planting grooves are formed above the planting frames, and planting boxes used for planting aquatic plants are arranged in the planting grooves in a matched manner. According to the pond ecological breeding system, the sandbag modules can be directly laid at the bottom of a pond to cover sludge, construction is easy, convenient and rapid, most of the sludge can be covered, it is avoided that bottom sludge suspends to affect water quality, and the problems that in the traditional technology, the work amount of hardening the bottom of the pond with cement is large, the construction period is long, and the cost is high are solved.

Description

technical field [0001] The invention relates to the technical field of breeding equipment, and more specifically, the invention relates to an ecological breeding system for crabs in southern regions. Background technique [0002] There are many ponds in the southern region, and the distribution area is wide. If it can be used for the cultivation of river crabs, it will be able to significantly increase the scale of river crab cultivation, realize the effective use of natural resources in ponds, and improve economic benefits. [0003] However, river crabs have higher requirements on water quality. Only when the water quality is good can the growth and development of river crabs be better, and the meat quality will be more delicious without peculiar smell. Most of the existing methods are to keep the water clear and fresh by regularly changing the water in the pond. However, most of the ponds in the south are mud ponds, with a lot of silt deposited. Therefore, in order to mai...

AI Technical Summary

Problems solved by technology

Most of the existing methods are to keep the water clear and fresh by regularly changing the water in the pond. However, most of the ponds in the south are mud ponds, with a lot of silt deposited. disease, so in order to maintain water quality, we can only increase the frequency of water changes, but frequent water changes increase the workload and cost

Some existing technologies hope to achieve the purpose of reducing silt by hardening the bottom of the pond with cement, but the amount of engineering is large and the cost of breeding is high, which is not conducive to the promotion of breeding
