A fish reef structure suitable for octopus farming in shallow sea areas

Abstract

The invention relates to a fish shelter structure suitable for culturing octopus in a neritic region. The fish shelter structure is characterized in that a fish shelter consists of a cover body and a base; a bolt hole is formed in the upper part of the cover body in a penetrating manner; the base is provided with a connecting shaft; the upper end face of the connecting shaft is provided with a nut hole; the cover body is fixedly connected with the base by penetrating the bolt hole through a set bolt and screwing the set bolt in the nut hole; a hook is arranged on the top of the cover body; a plurality of floating balls are connected in series above the hook through a rope; a plurality of floaters are connected in series below the base through a rope; a rope between the floater and the base is connected with a positioning anchor through a fixed pulley; the positioning anchor comprises an anchor body; a plurality of accommodating cavities are formed in the anchor body; barbs are arranged in the accommodating cavities; the outer surfaces of the barbs are provided with a plurality of wedges; the barbs are rotationally connected with a lug on the anchor body through pin rolls; limiting blocks are arranged outside the accommodating cavities. According to the fish shelter structure, the artificial environment for culturing the octopus is optimized by simulating a natural fish shelter, and the fish shelter structure is favorable for inhabitation of the octopus.

Description

technical field [0001] The invention relates to a fish reef structure suitable for octopus cultivation in shallow sea areas. Background technique [0002] As a fishery habitat improvement technology, artificial reef construction has played an important role in restoring fishery habitats and increasing fishery resources. The current research focus of fish reef technology is on the scientific research on the mechanism of artificial reef environment, while artificial reef As an important part of artificial reef construction, there is no in-depth research on the delivery technology and method. The deployment of artificial reefs plays a pivotal role in all aspects of artificial reef construction. Safe, accurate and efficient deployment of artificial reefs will not only enable artificial reefs to exert their maximum habitat transformation function, but also It saves a lot of manpower and material resources for the construction of artificial fish reefs.
