Vertical sinilabeo rendahli trapping cage used in great lake

Abstract

A vertical sinilabeo rendahli trapping cage used in a great lake comprises a cage body rack. Reinforced steel bar stand columns are welded to form the cage body rack; the external surface of the cage body rack is covered with a net sheet wall to form the cage body; the cage body is rectangular; the front and back ends of the cage body and the two sides are provided with six fish inlets; the six fish inlets are individually provided with steel bar inverted burs; the six steel bar inverted burs are fixed by the net sheet wall; one corner of the top of the cage body is provided with a fish fetching door; one end of the fish fetching door is fixed by a hinge and the other end is connected with a hook; the fish fetching door can be closed or opened with an action of the hook; two fish trapping bags are mounted on the bottom of the cage body rack; and the two fish trapping bags are respectively fixed by a fish trapping bag stay rope.

Description

technical field [0001] The invention relates to a cage for catching dace, in particular to a vertical trapping cage for dace in large lakes, and belongs to the technical field of fishing cages. Background technique [0002] Dace inhabits rivers and mountain streams with relatively fast currents. It is a benthic fish and likes to live in groups. It often appears in the gaps between rocks, looks for food on the gravel substrate, uses the sharp horny edge of the lower jaw to scrape raw algae, and also eats branches, leaves, and debris of higher plants. The growth of Chinese dace is relatively slow, and the average individual is 1-2 kg, the largest individual can reach 5 kg, and the yield is relatively high in the place of production. It is a common edible fish in Sichuan Province. Its meat is firm and crisp, very delicious and rich in oil, similar to herring, and is regarded as a precious food. [0003] At present, when people catch dace in the Great Lakes, they usually use d...

Problems solved by technology

[0006] Beneficial effects of the present invention: due to the adoption of the above-mentioned scheme in the present invention, the bait placed in the cage will emit a strong fishy smell after the Dahu vertical trapping dace cage is launched into the water, and a strong penetrating force will be produced in the water The force quickly spreads to far away waters, so that after the dace smells a strong fishy smell, it will quickly search for the source of the smell, and enter the cage to grab the bait without knowing it. Because the cage is equipped with Six fish inlets and six steel bars have inverted whiskers, and the inverted whiskers are large in front and small in back, so the dace that enters the cage cannot escape, and is caught, and the purpose of the present invention has been achieved. The mud carp is not frightened, it enters voluntarily, the labor intensity is small, the catch is high, the cage is not damaged, the effect of catching dace is good, the structure is simple, and the advantages are convenient to use, which effectively overcomes the existing pulling net and casting net. The defects of high labor intensity, high missed catch rate, serious damage to net gear and poor fishing effect exist in the fishing of dace in the Great Lakes
