Special stereo multi-layer type swimming crab culture device

Abstract

The invention relates to the technical field of aquaculture, specifically to a special stereo multi-layer type swimming crab culture device. According to the invention, the device is externally connected with a water-level control unit--a culture barrel, wherein a plurality of culture disks are distributed in the culture barrel along axial direction at an interval, each culture disk comprises a plurality of culture areas and a hollow area, and each culture area is provided with a water inlet channel; the interior of the culture barrel is provided with a water delivering pipe, and the wall of the water delivering pipe is provided with water outlets which can be communicated with the water inlet channel of the culture area; the top of the culture barrel is also provided with a blanking unit which is connected with a plurality of feeding channels that respectively extend to a corresponding culture disk; the culture disks are also provided with feed-dividing disks at outlets of corresponding feeding channels; and the feed-dividing disks sleeve the water delivering pipe, and the bottom parts of the feed-dividing disks are provided with feeding pipes which are respectively communicated with a corresponding culture area. The special stereo multi-layer type swimming crab culture device provided by the invention makes full use of the spatial volume of the culture barrel, so culture space is greatly saved under the condition of invariable yield; and feeding of each culture area is realized through the blanking unit and the feed-dividing disks, so the feeding is more uniform, and the unity of culture specifications is ensured.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a three-dimensional multi-layer crab special-purpose cultivation device. Background technique [0002] At present, as the demand for swimming crabs continues to increase, the number of wild swimming crabs is far from meeting people's needs. The output of artificially cultured swimming crabs continues to increase, but with the increase in production, problems in the breeding process also appear. [0003] First of all, due to the aggressive nature of Portunus crabs, the phenomenon of cannibalism and killing each other is very serious in the artificial breeding process, which is one of the main factors limiting the breeding output; secondly, in artificial breeding, in order to increase production, the breeding density is often increased. The water pollution in the breeding pond is serious, which not only increases the death rate of crabs, but also seriously affects the quality o...

Problems solved by technology

However, the swimming crab device in the above-mentioned patent has no layered structure, and all swimming crabs are cultivated in the same pond, which cannot make full use of the space and occupies a large area; moreover, the cultivation pond of the above-mentioned patent cannot solve the problem of uneven artificial feeding, although There are also multiple small ponds in the breeding pond, but the number of crabs in the small pond is more than one. It is still difficult to ensure that the swimming crab breeding specifications are consistent if multiple crabs are raised in one small pond.
