What is purse seine fishing? Purse seine fishing takes place in the open ocean, using a large net - the purse seine - to target dense schools of single-species pelagic (midwater) fish like tuna and mackerel.

A purse seine is a large wall of netting deployed around an entire area or school of fish. The seine has floats along the top line with a lead line threaded through rings along the bottom. Once a school of fish is located, a skiff encircles the school with the net.

The purse seine is a preferred technique for capturing fish species which school, or aggregate, close to the surface: sardines, mackerel, anchovies, herring, and certain species of tuna (schooling); and salmon soon before they swim up rivers and streams to spawn (aggregation).

Purse seines are used in the open ocean to target dense schools of single-species pelagic (midwater) fish like tuna and mackerel. A vertical net ‘curtain’ is used to surround the school of fish, the bottom of which is then drawn together to enclose the fish, rather like tightening the cords of a drawstring purse.
