Abstract

The invention discloses a self-sinking fish reef comprising a self-sinking support. The self-sinking support comprises a platform, a trapezoidal support frame is arranged below the platform, and the support frame is connected by side support rods on the side faces and a bottom support rod at the bottom. Limiting columns are arranged on the portion, on the inner sides of the side support rods, below the platform. A positioning boss protruding upwards is arranged on the portion of the upper side of the platform. Multifunctional tubes are arranged at the positions close to the edge of the positioning boss. A combined reef body is arranged above the platform, and comprises annular reefs matched with the edge of the positioning boss. Through positioning holes capable of accommodating pins are formed at the side positions, close to the tops or bottoms, of the annular reefs. The self-sinking fish reef has the advantages of high sinking speed, layout stability, high proliferation efficiency, high success rate and capability of replacing proliferation varieties as required.

Description

technical field

[0001] The invention relates to an artificial fish reef, in particular to a self-submerged fish reef. Background technique

[0002] Artificial fish reefs refer to specially constructed fishery engineering facilities in waters where fish swim through caves, have suitable natural conditions and do not hinder other operations. The purpose of the artificial reef is to improve the ecological environment of the water area, attract fish to gather, breed or feed and grow, thereby forming a stable fishing place. In addition, there are artificial reefs specially set up to protect fish resources, cultivate larvae or induce fish schools to swim in a directional way. Humans have built artificial reef fisheries dating back to the 19th century. As early as 1860, American fishermen discovered the role of reefs. The United States and Japan are the countries with the earliest history of artificial reef construction, large scale, wide range and characteristics in the world. ...
