Herring seiner

Seine (/seɪn/ SAYN) fishing (or seine-haul fishing) is a method of fishing that employs a seine or dragnet. A seine is a fishing net that hangs vertically in the water with its bottom edge held down by weights and its top edge buoyed by floats. Seine nets can be deployed from the shore as a beach seine, or from a boat.

Boats deploying seine nets are known as seiners. There are two main types of seine net deployed from seiners: purse seines and Danish seines.

"Seine, or Sean [comes from:] (O. Fr. seigne, mod. seine, Lat. sagena, Gr. σαγήνη, a draw-net)", according to Encyclopædia Britannica in 1926.

Seines have been used widely in the past, including by stone age societies. For example, with the help of large canoes, pre-European Māori deployed seine nets which could be over one thousand metres long. The nets were woven from green flax, with stone weights and light wood or gourd floats, and could require hundreds of men to haul.

Native Americans on the Columbia River wove seine nets from spruce root fibers or wild grass, again using stones as weights. For floats they used sticks made of cedar which moved in a way which frightened the fish and helped keep them together.

Seine nets are also well documented in ancient cultures in the Mediterranean region. They appear in Egyptian tomb paintings from 3000 BC. In ancient Greek literature, Ovid makes many references to seine nets, including the use of cork floats and lead weights.
