Seining

Seining has always been a way to catch commercially important fish for food, but in managing fish stocks seining is mainly used to reform the structure of less important fish stocks. Seining is one of the oldest methods of catching fish. It has a history of thousands of years. Seine fishing has been developed especially in Northern Finland, and seines that are used today in lakes are mainly from there. Seining (purse seining), which is an ancient method of fishing is used efficiently today to reduce overgrowth of fish stocks. It's so called "intensive fishing" and using it is possible to remove large amounts of fish fast. Seine fishing is usually the first method to use of managing fish stocks. Modern way of seine fishing is mechanical, so that it's possible to catch large amounts of fish efficiently from one place and then move to another place quickly. Professional seining can give hundreds of kilos of small fish seined out at one draw. Purse seining is a process of catching shoaling fish by encircling them with a net and as fish moves towards the back of the net they end up in a "purse". Purse prevents the fish escaping from the net. Benefits of seine fishing are based on good knowledge of water bodies and also that fish gathers to big shoals. In intensive fishing commercially important fish are separated from fish mass in purse and released.
