Description
Technical Field
The invention belongs to the technical field of aquaculture and ocean resource development, and particularly relates to an air supplement device for a settleable fish culture net cage.
Background
The negative effect of the offshore net cage fish culture on the environment has attracted people's attention, and the development of the seawater fish culture from the offshore net cage to the offshore (deep open sea) net cage has become the inevitable choice for the sustainable development of the mariculture industry. In order to utilize cold water resources at the lower part of the sea in summer to avoid enemy organisms of cultured fishes or to avoid severe hydrological conditions, people often need to submerge the fish-culturing net cage in a certain water layer under water in stages. However, sinking the cages underwater for a long time can affect the normal life and growth of some fishes.
People research on Atlantic salmon discovers that when the fish lives underwater for about 20 days, gas in swim bladders can partially overflow and cannot be supplemented, buoyancy of fish bodies can be influenced, swimming speed of the fish is increased, and growth speed of the fish is reduced. Therefore, for fish with similar physiological phenomena, it is sought to replenish the air during the long-term caisson culture.
