Crayfish three-dimensional breeding device and method

Abstract

The invention relates to a crayfish three-dimensional breeding device and method. The crayfish three-dimensional breeding device comprises a fixing base, the upper end of the fixing base is connected with the lower end of a PVC pipe, a climbing frame is installed on the side wall of the upper end of the PVC pipe, and the climbing frame comprises an outer spiral frame, an inner spiral frame, a connecting plate and a spiral net. The three-dimensional breeding method using the crayfish three-dimensional crayfish breeding device specifically comprises the following steps of component assembling, installing and positioning, young crayfish putting, daily management and adult crayfish catching. According to the crayfish three-dimensional breeding device and method, the PVC pipe serves as a main body foundation, the PVC pipe is low in price, easy to obtain, low in manufacturing cost and beneficial to large-scale application and popularization, the installation stability of the device is improved through the arrangement of the fixing base, the distribution uniformity of the crayfishes can be improved in a limited space through the arrangement of the spiral climbing frame, the occurrence probability of the clustering phenomenon is reduced, and growth of the crayfishes is facilitated.

Description

technical field [0001] The invention relates to the field of agricultural cultivation, in particular to a crayfish three-dimensional cultivation device and a three-dimensional cultivation method. Background technique [0002] The scientific name of crayfish is Procambarus clarkii. It belongs to the aquatic animals of Crustacea, Decapoda, and Crayfish. Crayfish is omnivorous, fast in growth, delicious in meat, and diverse in cooking methods. It is favored by consumers and is the middle and lower reaches of the Yangtze River in my country. An important freshwater aquaculture economic species in the region. Crayfish have strong climbing ability and weak swimming ability. They have the living habit of shelling and killing each other. In order to improve the production and effect of breeding, aquatic plants need to be planted whether in ponds or rice fields. Aquatic plants can be used for crayfish to climb and inhabit, avoid predators, and increase breeding space. At the same tim...

Problems solved by technology

However, this is also the peak season for the growth of aquatic plants. In the actual production process, due to the comprehensive influence of crayfish stocking density, aquatic plant planting density and breeding management measures, it is very difficult to reasonably control the biomass of aquatic plants, which in turn affects the breeding effect.

When the biomass of aquatic plants is low, it is not conducive for crayfish to climb, inhabit and avoid, affect the shelling of crayfish, and increase the chance of killing each other; when the biomass of aquatic plants is too high, under the conditions of photosynthesis, it is easy to cause dissolved oxygen and The drastic change of pH value is not conducive to the growth of crayfish, and it also increases the difficulty of managing aquatic plants and catching crayfish during the breeding process
