Crayfish burrowing system for three-dimensional cultivation

Abstract

The invention discloses a crayfish burrowing system for three-dimensional cultivation. The crayfish burrowing system comprises a tank, a plurality of bags connected with the tank and a lifting assembly connected with the bags, wherein openings are formed in the bags and connected to water channels, and a feeding port is formed in the upper part of each water channel; water guiding parts are arranged in the bags, and one end of each water guiding part extends into the corresponding water channel; the lifting assembly at least comprises pulleys and dragging parts, one end of each dragging part is connected with the closed end of the corresponding bag, and the free ends of the dragging parts wind around the pulleys, and rollers are arranged at included angles of the bags and the tank. According to the crayfish burrowing system, three-dimensional cultivation is realized, the cultivation quantity is increased, and space is saved; crayfishes can easily burrow and are convenient to fish and prevented from climbing to escape.

Description

technical field [0001] The invention relates to crayfish culture technology, in particular to a three-dimensional culture crayfish drilling system. Background technique [0002] Crayfish are suitable for living in wetlands, lakes and river ditches with shallow water bodies and abundant aquatic plants. Crayfish like shade but not light. They have different living environment requirements at different stages of the growth process. When crayfish reproduce and avoid natural enemies, It is necessary to dig holes, crayfish have a strong climbing ability, and anti-climbing devices need to be installed on the bank of the pool. [0003] As people's demand for crayfish increases, artificial breeding is essential. Artificial breeding of crayfish is often done in pools where the water in the pool is deep and the area is large, and the cost of shading is high. The anti-climbing device will affect the burrowing of crayfish, and the burrowing of crayfish on the bank slope will also affect...

[0003] As people's demand for crayfish increases, artificial breeding is essential. Artificial breeding of crayfish is often done in pools where the water in the pool is deep and the area is large, and the cost of shading is high. The anti-climbing device will affect the burrowing of crayfish, and the burrowing of crayfish on the bank slope will also affect the firmness of the bank slope, and the crayfish burrow is too deep and difficult to catch
