Multifunctional marine aquaculture device

Abstract

The invention relates to the technical field of artificial aquaculture, in particular to a multifunctional marine aquaculture device. The marine aquaculture device comprises a stereoscopic space composed of four columns and a connecting frame, the middle of the connecting frame is divided into an upper layer and a lower layer, the upper layer is an abalone breeding area, and the lower layer is a general fish breeding net cage; the abalone breeding area is provided with a plurality of abalone breeding net cages, open holes are formed in the upper surface of the connecting frame, abalone bait feeding ports of the abalone breeding net cages protrude from the open holes in the surface, and the upper surface of the connecting frame is further provided with a general fish bait feeding port communicated with the general fish breeding nets cage. According to the technical scheme, mixed breeding of abalones and general fishes is achieved, the comprehensive utilization rate of a certain sea areais increased, and the purpose of increasing economic benefits of a breeding enterprise is achieved. At the same time, vertical ascending and descending of the whole device is achieved by means of water inflow and drainage of ballast water tanks to replace artificial lifting of the breeding net cages, the stability is good, and the labor intensity of workers is low.

Description

technical field [0001] The invention relates to the technical field of artificial aquaculture, in particular to a multifunctional marine aquaculture device. Background technique [0002] In recent years, the marine aquaculture industry has developed rapidly. With the continuous expansion of aquaculture demand, the marine space resources available for aquaculture are becoming increasingly scarce. As a seafood with high nutritional value, abalone is loved by farmers. At present, seawater caissons are mostly used in the abalone breeding process. In the process of feeding feed and harvesting abalone, the staff need to drag the abalone breeding cages out of the water in groups, which is extremely labor-intensive; and effective abalone farming The depth is generally only 0.5m to 2m underwater, and the comprehensive utilization rate of the sea area is not high within a certain area of ​​aquaculture; while the effective aquaculture depth of common fish can reach 4m to 5m underwater...
