Intensive three-dimensional crab raising system

Abstract

The invention discloses an intensive three-dimensional crab raising system, which comprises a culture pond and a control device, wherein a vertical conveying device capable of annularly circulating is arranged in the culture pond; the conveying device comprises a transport segment and a vacant segment; a plurality of crab pots are uniformly suspended on the transport segment at intervals and the vacant segment is vacant; the culture pond is provided with a feeding device and a waste discharge device which are arranged at the upper part of the top of the conveying device; the control device is used for controlling the conveying device, the feeding device and the waste discharge device. Multi-layer placement of crab pots in the culture pond is achieved by adopting the vertical conveying device capable of annularly circulating; feeding and drainage work can be conveniently completed by using the feeding device and the waste discharge device; aquatic water is fully utilized; and the intensive three-dimensional crab raising system has the characteristics of high culture density and high automatic degree, has relatively economic benefits and is beneficial to popularization.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an intensive three-dimensional crab breeding system. Background technique [0002] The main economic crab breeding in my country includes three species of river crab, portunus trituberculatus, and blue crab. At present, the group breeding mode in outdoor earthen ponds is still the main mode. However, due to the aggressive nature of crabs, the phenomenon of cannibalism within species is serious Compared with other aquatic animals, the output per unit of breeding area is very low. For example, the yield per mu of Portunus trituberculatus and blue crab is about 30-50kg, which is only one-thirtieth of that of Penaeus vannamei. . Therefore, the low output per unit area of ​​pond group culture has become one of the main problems hindering the healthy and sustainable development of the crab farming industry. [0003] In recent years, with the diversification of breeding models, peop...

AI Technical Summary

Problems solved by technology

[0004] However, the current single-basket culture technology is not perfect, there is insufficient automatic management technology for bait feeding and residual bait, or it can only be cultured in a single layer, the amount of culture per unit area is small, and the three-dimensional culture and automatic culture cannot be well realized. The economic benefit is low, so it is difficult to be popularized on a large scale
