Basnig or balasnig are lift nets (salambaw) operated by a large outrigger boat called Basnigan. They use a large bag net suspended directly below or beside the ship. This net is attached to multiple temporary booms projecting from the ship's outriggers and detachable auxiliary masts. Modern basnig typically use generators and electric lights to attract fish and squid. This method is unique to the Philippines. It is common in the Visayas, particularly in the provinces of Capiz and Iloilo.

Lift nets, also called lever nets, are a method of fishing using nets that are submerged to a certain depth and then lifted out of the water vertically. The nets can be flat or shaped like a bag, a rectangle, a pyramid, or a cone. Lift nets can be hand-operated, boat-operated, or shore-operated. They typically use bait or a light-source as a fish-attractor. Lift nets are also sometimes called "dip nets", though that term applies more accurately to hand nets.
