Fish nets suitable for fish farming in fences on large water surfaces of reservoirs

Abstract

The invention discloses a fish blocking net suitable for large-range fence fish cultivation in a reservoir. The fish blocking net comprises a net body, a floating headrope, a waist headrope and a bottom headrope, wherein the top, the middle upper part and the bottom of the net body are respectively connected with the floating headrope, the waist headrope and the bottom headrope; the floating headrope is provided with a plurality of groups of floaters, and the bottom headrope is provided with a plurality of stone cages; the floating headrope is provided with a weight which is connected with a controller through a cable, and the controller can release and retract the cable. According to the fish blocking net disclosed by the invention, the resource of net sheets, headropes (cables) and the like are wide and are easily obtained (brought); the structure is simple, and the height, the width and the mesh size of the fish blocking net can be regulated according to the specific conditions, such as the section of a reservoir bay where the net is arranged and cultivated fish types; a ship passing opening is simply and conveniently opened and closed, and the management cost is extremly low; and the strength of the fish blocking net is good, the connection of the bottom headrope and the connected net sheets with the bottom substrate of the section where the net is arranged is tight and firm, and the function of preventing fishes in a fence from escaping is good.

Description

Technical field [0001] The invention relates to a fish blocking net suitable for fish breeding in large water surface fences of reservoirs, and belongs to a fence fish breeding facility. Background technique [0002] my country has abundant water surface resources in reservoirs. Except for reservoirs as drinking water sources, fishery development can be carried out in a moderate and planned manner, especially for the cultivation of filter-feeding fish that do not need to be fed. Among them, fenced fish farming uses reservoirs. An effective way to develop fishery economy with large water surface resources. At present, in terms of fenced fish farming facilities, in order to solve the problem of navigation of goods and personnel inside and outside the large water fenced fish farming area, various scientific research and production units have conducted long-term research and experiments and have made great progress. However, the existing large water surface fish blocking facilities, ...
