Since different age groups of carp are kept in different ponds, they are fished out and transported several times in their lives. Pond fishing starts with draining of water which lasts for a few days, during which scared fish are forced to move to the deepest point of the pond (fishery) where they are all crumpled together. In larger ponds, fishers will use bars to knock on the water in order to scare carp off and get them to the fishery.

ish are drawn out of water and "riddled" by pushing them roughly along a long bathtub with holes through which smaller fish fall. Some fish get stuck in the holes. Those who survive are then literally poured into crammed vats and transported. While in vats, they are sometimes forced to temporarily stay with predatory fishes with no possibility to escape.

In vats, on streets or at markets, they are constantly abused by workers who stir the water (throwing one carp over another), trying to find a fish of an appropriate weight. Carp that have been chosen to be killed at people's homes have it even worse as children often treat fish like bathe toys.
