Cage for trapping Bombay ducks in rivers and lakes

Abstract

The invention provides a cage for trapping Bombay ducks in rivers and lakes. The cage comprises a cage frame formed by connecting and welding rebar stand columns mutually. The outer side surface of the cage frame is covered with net piece walls and thus a rectangular cage body is formed. The two ends of the cage body are provided with fish inlets. The two fish inlets are connected with opening fixing frames inward in an inward-concave and extending manner. The opening fixing frames are connected and fixed through opposite pull of upper and lower net ropes. The opening fixing frames are provided with opening fixing frame fish inlets which are provided with inner tapered units. The inner tapered units extend inward and are connected with inner tapering openings and inner tapering opening pull ropes are used for connection and fixation of the inner tapering openings. The middle portion of one side of the top end of the cage body and a corner portion are provided with a cage lifting nose and a fish taking door. One end of the fish taking door is fixed by movable hinges and the other end is connected with a door hook through which the fish taking door can be opened and closed vertically. A fish trapping bag is arranged in the inner cavity of the cage body and fish trapping bag pull ropes are used for connection and fixation of the fish trapping bag.

Description

technical field [0001] The invention relates to a cage for trapping leading fish, in particular to a cage for trapping leading fish in rivers and lakes, and belongs to the technical field of fishing cages. Background technique [0002] At present, when people catch leading fish in waters such as rivers and lakes, they mainly use trawl nets, put the trawl nets into the water, start the lifting support rod to open the net gear, and start the tugboat to quickly pull the net gear to catch various fish ashore , although there is a large amount of fish caught, due to the fast speed of the boat, the fish caught are struggling desperately in the trawling net, causing various fish to be seriously injured during the struggle, and the mortality rate of the fish is high after being caught out of the water.

Problems solved by technology

[0005] Beneficial effects of the present invention: because the present invention adopts the above-mentioned scheme, after the rivers and lakes trap the faucet fish cages into the water, the bait placed in the cages will emit a strong fishy smell, and quickly spread to far waters, After the dragon head fish smells the smell, it will increase the hunger of the dragon head fish, and they will look for the source of the fragrance to find food, and enter the cage to grab the bait. Catch, can not escape, reached the purpose of the present invention; The rivers and lakes trapping faucet fish cage tool of the present invention has simple structure, large storage space, convenient transportation, easy operation, high amount of catching faucet fish, little damage to fish, and easy to catch. The advantage that the fish can be marketed fresh effectively overcomes the defects of the high mortality rate of the fish caught by the existing boat trawl nets in the waters of rivers and lakes and the inability to reach the market of the fish fresh
