A device for cultivating mixed organisms on the continental shelf

Abstract

The invention discloses a continental shelf hybrid organism cultivation device, which includes a floating base and a spherical sinking base. The floating base is provided with a floating ball on the outside, and an isolated upper chamber and a lower chamber are provided in the floating base. The upper chamber of the floating base is There is a bobbin for winding ropes inside, and there are a number of horizontal spools in the vertical direction below the floating base. The expansion base is arranged in rows, and a detachment mechanism is provided between the floating base and the expansion base to control the separation of the expansion base and the floating base one by one. A number of seaweed culture bricks are provided on the upper part of the sinking base, and the sinking base and the floating base are connected by ropes. , the rope runs through the middle part of each expansion base, and the sinking base is equipped with an inner cavity connected to the outside world. The present invention aims to provide a continental shelf mixed biological cultivation device with reasonable structure and diverse functions, which simultaneously provides food sources for fish groups and achieves good protection effects.

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
