Ecological circulation system for culter alburnus culture water

Abstract

The invention belongs to the technical field of culter alburnus culture, and particularly relates to a culter alburnus culture water ecological circulation system which comprises a culture pond, a plurality of rectangular supporting rods used for supporting and limiting are arranged at the outer end of the culture pond, and first sliding grooves used for limiting sliding of first connecting plates are formed in the rectangular supporting rods of the culture pond. The device comprises a culture pond and a threaded rod for transmission, the culture pond is connected with a first connecting plate through the threaded rod, a motor for transmission is arranged at the upper end of the first connecting plate, the lower end of the first connecting plate is connected with a third connecting plate through a second connecting plate, and an oxygen conveying pipe is connected with the third connecting plate through a connecting pipe. The connecting pipe is connected into the oxygen conveying pipe in a sleeved mode, inclined blocks and dense holes which are evenly distributed are arranged on the inner wall of the oxygen conveying pipe, the aerator serves as a driving end, oxygen is conveyed into the water pool through the connecting pipe, the oxygen can be better conveyed to all depths of the water pool under the action of the inclined blocks and the dense holes, and therefore the oxygenation effect is improved.

Description

technical field [0001] The invention belongs to the technical field of Cichlid aquaculture, and in particular relates to an ecological circulation system for Cichlid aquaculture water. Background technique [0002] The body length of the cockroach is usually 2-2.5 kg, very flat on the side, the back of the head is straight, the back of the head is raised, and the back of the body is nearly straight. The mouth is superior, the lower jaw is very thick and upturned, and the cleft is almost vertical; the eyes are large and located on the side of the head; the end of the hypopharyngeal teeth is hooked. There is a ventral rib between the base of the pelvic fin and the anus; the dorsal fin has powerful and smooth spines; the caudal fin is forked, and the lower lobe is slightly longer than the upper lobe; the back of the body is slightly blue-gray, silvery white on both sides, and each fin is gray-black. It is eaten in spring and summer. The meat is sweet and warm, and has the effe...

Problems solved by technology

[0003] The structure of the original water ecological circulation system for Cichlid aquaculture is too simple, and the function is single. However, Cichlid carp has a high demand for oxygen in the water body, and the effluent is easy to die. solve this problem
