Marine crop cultivation assistance reef

Abstract

The invention discloses a marine crop cultivation assistance reef comprising a float base and a spherical sunk base. A float ball is arranged outside the float base. Isolated upper cavity and lower cavity are arranged in the float base. A rope reel used for winding a rope is arranged in the upper cavity of the float base. A plurality of expansion bases arranged in parallel in a vertical direction are arranged below the float base. Detachment mechanisms under the control of which the expansion bases can be detached from the float base one by one are arranged between the float base and the expansion bases. A plurality of seaweed cultivation bricks are arranged on the sunk base and the expansion bases. The sunk base and the float base are connected through the rope. The rope penetrates the middle parts of the expansion bases. The sunk base is provided with an inner cavity communicating with the outside and a plurality of water permeation layers positioned below the inner cavity and communicating with the inner cavity. Expansion racks capable of rotating upwards are arranged at the bottoms in the expansion bases. The marine crop cultivation assistance reef provided by the invention has a reasonable structure and multiple functions. With the assistance reed, a food source is provided for fish stocks, and a good protection effect is realized.

Description

technical field [0001] The invention belongs to the field of marine organism development, and in particular relates to an auxiliary reef for marine crop cultivation. 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 g...

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
