Mullets, Carps and the Caspian Whitefish (Kutum) are the main species harvested during the season.
Some fishers in Iran’s northern province of Mazandaran use the traditional Parreh harvesting method. This is done using fishing nets with heights of 7 to 10 meters, which are up to 1,200 meters long.
The net is spread in the shape of a U letter at a certain distance from the shoreline, using a boat. The fishers then wait for the fish to get caught in the net.
When there are enough fish in the net, the fishers haul the net using a tractor and gather the fish.
