A multi-layered artificial fish reef

Abstract

The invention discloses a multilayer artificial fish shelter which is aimed at overcoming the defects that an artificial fish shelter is monotonous in function, fish shelters are distributed dispersedly after being put into a sea and sinking to a seabed, the gathering life of fish schools is not facilitated, and the fish shelter can not provide bait for the fish schools. The multilayer artificialfish shelter comprises a plurality of fish shelter units forming a circle. Each fish shelter unit comprises a sink-to-bottom shelter body and two suspended shelter bodies, wherein the sink-to-bottom shelter body and the two suspended shelter bodies are sequentially connected together, and floating bodies are connected between the two suspended shelter bodies and connected with the suspended shelter body on the upper side respectively. A plurality of communication pipes are evenly distributed on the outer wall of each suspended shelter body and are outward inclined from top to bottom. A plurality of storage grooves are formed in the outer wall of each communication pipe. Alga spores are placed in the storage grooves. An end cover is hinged to the opening position of the lower end of each communication pipe. A positioning base is arranged at the lower end of each communication pipe. A limiting supporting rod is hinged to the outer surface of each end cover. A buffering ball is installedat the lower end of each limiting supporting rod and abuts against the corresponding positioning base. A pull wire is connected with each limiting supporting rod. The lower end of each pull wire is connected with solid bait. The bait is placed in the communication pipes.

Description

technical field [0001] The present invention relates to a fish reef, and more particularly, it relates to a multi-layer artificial fish reef. Background technique [0002] Zhoushan is an important fishing ground in my country. It used to be rich in sea treasures such as large yellow croaker and yellow croaker. In recent years, due to environmental pollution, overfishing, and the destruction of the marine ecological environment, large yellow croaker, yellow croaker and other fish have become difficult to catch. In order to retain and protect floating eggs such as large yellow croaker and yellow croaker, improve the survival rate of juvenile fish, and multiply fishery resources, artificial fish reefs are put into the sea. Artificial reefs can improve the ecological environment of sea areas, create a good environment for marine organisms to inhabit, and provide places for fish to reproduce, grow, bait and shelter enemies. Therefore, the placement of artificial reefs plays an im...

AI Technical Summary

Problems solved by technology

[0003] The invention overcomes the problems that the artificial fish reef has single function, and after the fish reef is put into the seabed, the position distribution is relatively scattered, which is not conducive to the gathering and living of fish schools, and the fish reef cannot provide bait for fish schools, which is not conducive to the habitat of fish schools , providing a multi-layered artificial fish reef, which has various functions. The fish reefs are placed in a circle after sinking into the seabed, and the location distribution is concentrated, which is conducive to the gathering and living of fish schools. Bait, good for fish habitat
