This is a large-sized, collapsible fishing trap, designed for mass capture of small fish, shrimp, crayfish, or crabs.

The trap is folded during transport. By pulling a cord at the top, it opens and automatically "locks," stretching the net into a large, polygonal shape (with 16 sides).

It features 16 entrances around the perimeter. Each entrance has a "funnel" design (narrowing inward), allowing fish to enter easily but making their exit almost impossible.
