Drift Netting

Drift nets are lightweight nets made of monofilament nylon line. They are similar to gill nets but instead of being fixed to the seabed they are hung in mid water to create a wall of net. This is aimed at catching mid-water fish species such as herring and sardine. 
Traditional drift nets were shot at dusk, and would drift with the tides (hence the name) with the fishing boat attached to one end.
