Industrial aquaculture fish shelter

Abstract

The invention relates to an industrial aquaculture fish shelter. The industrial aquaculture fish shelter is characterized in that a first fish shelter body is composed of a cover plate and a base, a gas-filling device is arranged on the cover plate, and the gas-filling device which is located in a cavity is connected with a gas bag device; the base is provided with a plurality of through holes, and a plurality of concave pits are formed in the outer surface of the cover plate; an arc-shaped panel body of a second fish shelter body is arranged on the outer side of a star-like structure and partially covers the star-like structure, and the arc-shaped panel body and the star-like structure define one or more containing bodies with the two ends opened; an anchor body of a positioning anchor is provided with a plurality of containing cavities, barbs are arranged in the containing cavities, and the barbs are in rotation connection with a convex block on the anchor body through pin shafts. According to the industrial aquaculture fish shelter, the first fish shelter body can be matched with the positioning anchor to control the suspension height of the fish shelter by inflating and deflating the gas bag, and the second fish shelter body is of a porous structure and has the advantages of being large in concealed space, high in concealing property, good in water body circulation and the like; the positioning anchor is matched with the first fish shelter body and can regulate the suspension depth to conduct artificial enhancement, and the enhancement effect is good.

Description

technical field [0001] The invention relates to a fish reef for factory farming. 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. Contents of the invention [0003] Aiming at the problems existi...
