Pots and traps
Fishing with traps and pots is one of the oldest fishing methods. Our Stone Age ancestors used this method, which involves attaching the baited cages to lines and submerging them in the water. Unlike trawling, for example, it is one of the more passive fishing methods and also one of the best methods for preserving fish stocks.
Pots often resemble cages or baskets with one more openings (funnels) and are placed on the ocean floor, with or without bait.
Once the fish has swum into the pot, it cannot escape due to the funnel-shaped entrance. However, if the animal has not yet reached the desired catch size, it can get out through the escape hatches. This enables selective fishing.
