Cascading underflow recoil culture system of Penaeus japonicus

Abstract

The cascading underflow recoil type Penaeus japonicus culture system includes a bracket and a plurality of culture tanks, and the multiple culture tanks are horizontally arranged on different heights of the bracket; the culture tanks are provided with corresponding recoil water pipes, and the recoil water pipes are set At the bottom of the aquaculture tank; the aquaculture tank is also provided with a support plate, a sieve silk cloth and a bottom sand, the support plate is laid above the recoil water pipe, the sieve silk cloth is laid above the support plate, and the bottom sand is laid on the sieve silk cloth Above; the bottom of the culture tank is also provided with an overflow pipe and a drain, and the overflow pipe and the drain are located at the opposite ends of the culture tank; compared with the prior art, the bottom flow recoil is used to solve the problem that the bottom sand has no flowing water. For the black bottom problem caused by hypoxia, the oxygen-enriched water flows upward in the form of recoil to maintain the ecological stability of the sand bottom and solve the disease problem caused by the deterioration of the bottom.

Description

technical field [0001] The invention belongs to the technical field of mariculture, in particular to a cascading underflow recoil type Penaeus japonicus culture system. Background technique [0002] Penaeus japonicus is a nocturnal animal and has the habit of submerging sand during the day, so it cannot be cultured without a sandy bottom. However, because there is no water flow on the contact surface between the traditional sand bottom and the bottom of the pond, it will cause the deposition of feces, residual bait or other organic matter. Under anoxic conditions, it is easy to have black bottom or bottom deterioration, which will cause the disease of Penaeus japonicus. The survival rate of breeding is not high. [0003] At the same time, due to the bottom-diving characteristics of Penaeus japonicus and its strong territorial awareness, the traditional planar culture density cannot be increased, and the output is limited.

AI Technical Summary

Problems solved by technology

[0002] Penaeus japonicus is a diurnal and nocturnal animal. It has the habit of submerging sand during the day, so it cannot be cultured without a sandy bottom.

However, because there is no water flow on the contact surface between the traditional sand bottom and the bottom of the pond, it will cause the deposition of feces, residual bait or other organic matter. Under anoxic conditions, black bottom or bottom quality problems are prone to occur, which will cause diseases of Penaeus japonicus. The survival rate of breeding is not high

[0003] At the same time, due to the bottom-diving characteristics of Penaeus japonicus and its strong territorial awareness, the traditional flat culture density cannot be increased, and the output is limited.
