A kind of prawn culture pond device for aquaculture

Abstract

The invention discloses a prawn culture pond device for aquaculture. The technical problem to be solved is that the defecation outlet of the existing prawn culture pond is arranged in the center of the pond bottom, which is easy to form silt and blockage, which is not easy to clean, and easily makes the prawn feces or residual The problem of secondary pollution caused by bait to aquaculture water. In the present invention, a feces cleaning box is arranged at the bottom of the pool body, and the left slope, the right slope and the rear slope are inclined to the exposed part of the excrement cleaning box at the bottom of the pool body, and the shrimp feces or residual bait can be rolled along the left slope, the right slope or the rear slope. Enter the feces cleaning box and accumulate in the feces removal drawer in the feces cleaning box. When cleaning is required, first use the movable baffle to block the connection and seal between the feces removal drawer and the pool body. The feces removal drawer can be pulled out from the front side of the pool body , easy to clean, and will not form silt. At the same time, when drainage is required, on the basis of pulling out the defecation drawer, the movable water baffle is controlled to move backward, forming a drainage gap at the bottom of the pool body, and the drainage is rapid.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a prawn culture pond device for aquaculture. Background technique [0002] Prawns belong to Arthropoda, branchial subphylum, crustacea, soft armor subclass, decapod order, swimming suborder, prawn family, and genus prawns. The body of prawns is long and slightly flattened, dioecious, adult females are larger than males, and their body color is also different; the body color of Chinese prawns is gray and blue, and the body color of males is yellow. The body of prawns is covered by a layer of chitin exoskeleton carapace, which is secreted by the epidermal cells below it. The body of prawns can be divided into cephalothorax and abdomen, consisting of 21 segments. Except for the first and last segment, each segment has a pair of appendages. In my country, the Yellow Bohai Sea, Liaoning Lvshun, Hebei, Shandong Province and the coastal areas of Tianjin are important ...

AI Technical Summary

Problems solved by technology

[0003] In the process of prawn farming, a good breeding environment can improve the survival rate of prawns and help to increase the yield of prawns. However, the problem in the current culture ponds is that the defecation port is set in the center of the bottom of the pond. If it is blocked by silt, it is difficult to clean. It is easy to cause secondary pollution of shrimp feces or residual bait to the breeding water body, and it is difficult to form a clean and healthy growth environment for shrimp
