Mechanical fishing device for aquiculture fixed platform and application thereof

Abstract

The invention relates to a mechanical fishing device for an aquiculture fixed platform, which comprises a fishing rack, wherein, the fishing rack comprises an upright stanchion and a fixing steel cable; a main guy cable is arranged on one side of the fishing rack; a windlass installed on the land is sheathed with one end of the main guy cable; the other end of the main guy cable is connected with a lifting cord arranged at the upper part of a fishing net; a large net cage is arranged in the fishing rack; the large net cage comprises the fishing net, a net cage frame and a net cage bottom net; a fish passage opening is formed on one side of the fishing net; and the fishing net is communicated with a hanging pool through the fish passage opening and a guiding net. The mechanical fishing device protects water resources, saves water resources, is fast to fish, can catch fish at any time, can catch big fish but leave small fish according to production and market specifications of any cultured fish species, can enable fish to appear on the market by choosing time and date according to the requirements of the market and the ideal price, can effectively reduce unnecessary death of fish, and can control diseases of fish in time with the help of good living areas.

Description

technical field [0001] The invention belongs to the technical field of fish farming equipment, and relates to an aquaculture fixed platform mechanical fishing device suitable for use on water surfaces such as ponds, mountain ponds, reservoirs, lakes, large rivers and splash beaches of more than 10 mu and its application. Background technique [0002] Aquaculture farmers have a lot of headaches for catching commercial fish: first, they cannot protect the good water quality of the large water surface from being wasted and discharged due to fishing in dry ponds, thus wasting water resources; second, the fishing process often requires a lot of labor, which increases the Labor intensity increases the cost of manpower, material and financial resources; third, the fishing work is slow, and each fishing process requires a lot of time; fourth, it is seriously limited by time and seasons, and the breeding often has to be carried out according to changes in time and seasons. fifthly, t...
