A kind of multifunctional cabin combination artificial fish reef

Abstract

The invention discloses a multifunctional cabin combined artificial fish reef, which comprises a lower quadrangular platform main body, a middle support column and an upper umbrella-shaped structure. cabins, each cabin communicates through openings, and some cabins are darkroom structures that do not directly communicate with the outside world. There are algae attachment bases and openings, the upper surface and slope of the main body of the quadrangular platform are rough surfaces, and the upper surface of the top umbrella structure is a porous surface that is easy for algae to adhere to. The artificial fish reef is rich in shadow structure, and the multi-chamber structure can be a refuge, rest and spawning place for a variety of fish. The porous plastid on the surface is easy for algae and invertebrates to attach, and the attachment density is high. It is suitable for fish, sea cucumbers, Abalone etc. provide bait.

Description

technical field [0001] The invention belongs to an underwater ecological artificial fish reef engineering facility, in particular to an artificial fish reef with a combination of multifunctional cabins. Background technique [0002] The ecosystem formed by artificial reefs has played a huge role in the improvement and restoration of sea habitats. Putting in artificial reefs can effectively protect juvenile fish and shrimps, improve their survival rate, and provide fish with a good habitat and feeding places , Contribute to the increase of resources doubling or dozens of times. my country has paid more and more attention to the construction of artificial reef ecosystems, and the national capital investment and construction scale have increased year by year. 110 national-level marine ranch demonstration areas have been approved and established. In the "Central No. 1 Document", it is clearly required to develop modern marine ranching and strengthen scientific and technological...

AI Technical Summary

Problems solved by technology

This type of reef has a rich surface area and good air permeability, which can be used by algae and invertebrates to attach and provide rich bait for sea cucumbers, abalones and other sea treasures. However, this type of reef has a simple structure and low technological content.

The tower-type fish reef has a large number of hollows, and the internal complex and hollow structure can have a significant impact on the flow field around the reef, which can produce complex flow field effects and effectively provide rich nutrients and nutrients for the surrounding reef. Bait, which can attract more reef fish to gather and migratory fish to inhabit, but its surface area is relatively small, which is not conducive to algae attachment

Some fishes and cephalopods have complicated spawning environment requirements, and like environments with less light, slow flow velocity, and high concealment. The internal space of the existing fish reef structure is more than the direct connection with the outside world, which is not conducive to the spawning of such animals. Therefore, the development structure Complicated, with a darkroom structure not directly connected to the outside, and with a large surface area, a multifunctional artificial reef suitable for algae attachment, marine treasure proliferation and fish collection is very necessary
