Continental shelf mixed organism cultivation device

Abstract

The invention discloses a continental shelf mixed organism cultivation device. The continental shelf mixed organism cultivation device comprises a floating base and a spherical sunk base. The outside of the floating base is provided with floating balls, an upper cavity and a lower cavity which are separated are disposed in the floating base, a reel used for winding ropes is disposed in the upper cavity of the floating base, an plurality of expanding bases which are arranged in parallel in the vertical direction are disposed under the floating base, and releasing mechanisms used for controlling the expanding bases to releasing from the floating base one by one are disposed between the floating bases and the expanding bases. A plurality of alga cultivation bricks are disposed on the sunk base, the sunk base is connected with the floating base through ropes, the ropes penetrate through middle portions of all the expanding bases, an inner cavity communicating with the external environment is disposed in the sunk base. The invention aims to provide a continental shelf mixed organism cultivation device being reasonable in structure and various in function, capable of providing food for fish shoal and a good protective effect.

Description

technical field [0001] The invention belongs to the field of marine organism development, and in particular relates to a continental shelf mixed organism cultivation device. Background technique [0002] In the marine biological industry, fish multiplication and seaweed multiplication are the mainstream directions at present. In marine fisheries, various fish gathering devices such as artificial reefs will be used to attract and protect fish schools. To achieve fish gathering; in terms of seaweed proliferation, at present, seaweed reefs are mainly used as units to establish seaweed farms with a certain area to provide a good basis for seaweed attachment and proliferation. However, in the prior art, it is inconvenient to put and set fish reefs and algae reefs. This is because most of the fish reefs need to sink to the bottom (sea bottom) or close to the bottom of the sea, but after the fish reefs are placed, the primary fish gathering effect is poor, and it is difficult to ...

Problems solved by technology

However, in the prior art, it is inconvenient to place and set fish reefs and algae reefs.

This is because most of the fish reefs need to sink to the bottom (sea bottom) or close to the bottom of the sea, but after the fish reefs are placed, the primary fish gathering effect is poor, and it is difficult to form a good micro-ecosystem on the bottom of the sea; algae reefs can provide more food for fish schools source, but because many seaweeds (especially artificially propagated seaweeds, such as sargassum and sargassum, etc.) grow relatively fast near the sea surface (intertidal zone, within tens of meters under the sea, etc.), on the seabed due to light exposure Poor and slow growth, so the algae reefs are usually placed closer to the sea surface, but it is difficult to provide good protection for fish schools near the sea surface, so the best fish gathering effect cannot be achieved
