Breeding device and breeding method for bottom-dwelling shellfishes

Abstract

The invention discloses a breeding device and a breeding method for bottom-dwelling shellfishes. The breeding device comprises a bottom plate and side walls extending upwards from the periphery of the bottom plate, and the bottom plate and the side walls form a breeding pond; the breeding device further comprises a partition, gauze, a sand layer, a water inlet pipe and a water outlet pipe; the partition is arranged on the bottom plate, and a plurality of through holes are formed in the partition; the gauze is laid on an inner side of the breeding pond and used for covering the bottom plate and the side walls of the breeding pond, and the gauze is positioned on one side, far away from the bottom plate, of the partition; the sand layer is laid on the gauze; the water inlet pipe is arranged above the breeding pond, and water outlets of the water inlet pipe are formed in the breeding pond; the water outlet pipe is mounted at the bottom of the breeding pond and penetrates through a position close to the bottom plate from the bottom plate or the side walls. The breeding device and the breeding method for the bottom-dwelling shellfishes can solve a problem of high possibility of causing disease occurrence of the bottom-dwelling shellfishes due to inconvenient cleaning caused by direct discharge of excrements of the bottom-dwelling shellfishes into the sand layer in the prior art.

Description

technical field [0001] The present invention relates to an aquaculture device and a culture method, in particular to a benthic shellfish and crustacea culture device and a culture method. Background technique [0002] In the prior art, the artificial culture of benthic crustaceans such as swimming crabs and clams is to directly spread sand on the bottom of the culture pond, and the crabs and clams are put into the culture ponds for regular feeding. Since the feces and food residues of swimming crabs and flower clams are directly discharged into the sand layer, they will produce a mixture containing nitrogen and phosphorus after decomposition, resulting in pool water pollution. This is also the cause of the disease of swimming crabs and flower clams. Changing the water frequently and cleaning the sand layer is a heavy workload. Contents of the invention [0003] Therefore, one of the purposes of the present invention is to provide a benthic shellfish and crustacean culture...
