A reef body suitable for marine algae and fishes

Abstract

The invention provides a reef body suitable for marine algae and fishes. The reef body comprises a floating base and a spherical sinking base. The outer portion of the floating base is provided with a floating ball; the floating base is internally provided with an upper cavity and a lower cavity which are isolated from each other; the upper cavity of the floating base is internally provided with a winding reel used for winding ropes; a plurality of extension bases arranged in parallel in the vertical direction are arranged under the floating base; a disengagement mechanism enabling the extension bases to be disengaged from the floating base on by one is arranged between the floating base and the extension bases; each of the sinking base and the extension bases is provided with a plurality of alga cultivation bricks; the sinking base is connected with the floating base through a rope; the rope penetrates through the middle portion of each extension base; the sinking base is provided with an inner cavity leading to the outside; the bottom of the inside of each extension base is provided with an extension frame capable of rotating upward. The reef body suitable for marine algae and fishes is reasonable in structure, is multifunctional, and is capable of providing food for fishes and achieving a good protection effect.

Description

technical field [0001] The invention belongs to the field of marine life development, in particular to a reef suitable for marine algae and fish. 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 form a good micro-ecosystem ...

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
