Abstract

The invention relates to an acete chinensis trap net capable of releasing rhopilema esculentum and an assembling method thereof, and belongs to the technical field of marine fishing. Under the circumstance of not changing the performance of catching acete chinensis, rhopilema esculentum blocking and separating net pieces are obliquely and additionally installed in a main net in a single body tapercapsular bag shape to form a net-within-net structure, and a rhopilema esculentum releasing opening is reserved in the back middle position of an upper side gap of a main netting in the single body taper capsular bag shape. The suitable integral floating and sinking ratio is selected, a big floating ball is additionally installed in the net, and by adjusting the length of a big floating ball outline, aimed fishing is conducted. The trap net is simple in structure, easy to manufacture, convenient to operate and low in cost; the rhopilema esculentum can be effectively released, and the fishingperformance of the acete chinensis trap net cannot be influenced.

Description

Technical field: [0001] The invention belongs to the technical field of marine fishing, and in particular relates to a hairy shrimp stretching net capable of releasing jellyfish and an assembly method thereof. technical background: [0002] Chinese hairy shrimp (Acetes chinensis Hansen), which belongs to the order Decapod, Prunidae, and the genus Acetes chinensis, is commonly known as hairy shrimp. Body length 26-40mm, 1-year-old small planktonic shrimp, flat side, very thin carapace, transparent body color. The philodendrons gather in the bay or near the estuary, and their swimming ability is relatively weak. When they move, they mainly swim in the direction of the tide. They do not have the habit of long-distance migration, and only move in directions with the seasons. It is distributed along the coasts of my country, with the largest number in the Bohai Sea. It is an important fishing target for coastal netting operations. Except for a few fresh products, most of them ar...
