Hung-culture-type ecological crab culture equipment

Abstract

The invention provides hung-culture-type ecological crab culture equipment and belongs to the field of aquaculture. The equipment comprises a cuboidal frame body, hung netting and surrounding netting,wherein upper and lower bottom faces of the frame body are composed of a plurality of transverse pipes and longitudinal pipes which are arranged in a uniformly-spaced manner, the upper and lower bottom faces form the cuboidal frame body through vertical pipes, the surrounding netting is separately laid on a front face, a back face, a left face, a right face and the lower bottom face of the cuboidal frame body and is steel-wire surrounding netting, the maximum pore size of the surrounding netting is smaller than the minimum circumferential diameter of crabs during crab culture, the hung netting is hung in the frame body, and the minimum pore size of the hung netting is greater than the maximum circumferential diameter of the crabs of a harvesting stage. According to the hung-culture-type ecological crab culture equipment, a dissolved oxygen monitoring device and a miniature oxygen supply device are further arranged simultaneously, so that the dissolved oxygen number of culture water can be monitored in real time, oxygen is supplied to the water, and ecological, environment-friendly and efficient crab culture is achieved.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a hanging-type ecological crab-raising equipment. Background technique [0002] Crab (scientific name: crab) is a crustacean of the decapod short-tailed suborder, especially the species of the short-tailed family (true crab). It also includes some other types, such as about 4,700 species of crooked tails. Its distribution is found in all oceans, rivers and land. The tail of the crab is different from other decapods (such as shrimps, lobsters, and crayfishes). It is curled under the chest, and the carapace is usually broad. The crab's sideways gait is familiar and characteristic of most crab species. Species of the Portunidae family, and others, swim with flat paddle-like appendages, dexterous movements, and powerful pincers. Our country is rich in crab resources. Among them, hairy crabs from Taihu Lake, Gaoyou Lake, and Yangcheng Lake in the lower reaches of the Yangtze River are t...

Problems solved by technology

[0004] The prior art, such as the Chinese invention authorized patent document, authorized announcement number CN 101669450 B, this invention discloses a hanging culture high-density ecological shrimp culture and water quality purification device, the invention device includes a floating frame, the floating frame is composed of several horizontal Composed of pipes and longitudinal pipes, the horizontal pipes or longitudinal pipes are connected with water inlet and outlet control valves, and baskets and hanging nets are arranged between the horizontal pipes arranged at intervals. The ends are connected in series on the hanging net rod to form a soft mesh, and the hanging net is placed between the horizontal pipes arranged at intervals through the hooks at both ends of the hanging net hanging rod, which can be used to increase the density of breeding and purify the pollution caused by breeding. However, the high-density ecological shrimp farming and water purification device in this invention is only suitable for cultivating shrimps in still water, and only provides hanging nets for shrimps to cling to without limiting the activity area of ​​shrimps. It is not suitable for rivers and lakes For open water baths such as the sea, when the dissolved oxygen in the culture pond is low, an oxygen supply machine is required, and the device cannot measure the dissolved oxygen in the pool water. The basket and hanging net will be rusted if soaked in water for a long time, not only Harm the health of aquatic organisms and increase the cost of breeding
