Underwater net box culturing system

Abstract

The invention discloses an underwater net box culturing system. A square framework type net box with upper and lower two layers is sealed and formed by standard members of a plastic water supplying pipe and a three-way joint, four-way joint, bending head thereof and the like, and four fixing ropes are fastened to the bottom of the framework type net box to be connected with pulleys on four stone weights on the seafloor. The overall ratio of the framework type net box can be controlled by a diver by increasing or reducing sand bags at the bottom of the framework type net box on the sea floor, the framework type net box can be allowed to be conveniently moved between the sea surface and the sea floor freely by sea surface workers by controlling the lengths of the four fixing ropes, and the framework-type net box can be allowed to float on any of water layers including the sea surface. The net box gets close to the sea surface as much as possible because the surface layer temperature of sea water in spring is high, and the net box gets close to the sea floor as much as possible to evade high temperature. When a typhoon comes, the net box can be sunk onto the seafloor in advance. The net box culturing system has the advantages that the free moving between the sea surface and the seafloor after the net box is put in the water can be achieved without any hoisting equipment, and the utilization rate of a culturing sea area is greatly improved.

Description

technical field [0001] The invention relates to a seawater cage culture system. Background technique [0002] At present, most of the aquaculture cages are erected on the sea surface, and various types of aquaculture floating rafts occupy the upper surface resources of the aquaculture sea area, resulting in the lack of nutrients in the upper surface layer of the aquaculture sea area, and most of the bottom resources of the aquaculture sea area are idle. The main reason is that the cages are fixed on the bottom of the sea, which is inconvenient for cleaning, harvesting and daily management. If the cages can be freely moved between the sea surface and the seabed, the daily management work such as cleaning the cages and harvesting cultured animals can be performed on the sea surface, which can greatly improve the utilization rate of the breeding sea area. Contents of the invention [0003] In order to overcome the inconvenient problem of setting net cages on the seabed for c...
