A hand net with a long handle is often called a dip net. When it is used by an angler to help "fetch out" or "land" a hooked fish, it is called a landing net. [1] Hand nets have been used since antiquity for catching fish near the surface of the water, especially feisty, powerful ones such as muskellunge or northern pike.
The Puretic power block is a special kind of mechanised winch used to haul nets on fishing vessels. The power block is a large pulley of aluminium with a hard rubber-coated sheave .

Tangkal or bintahan are large stationary lift nets. They use box-shaped nets and are operated from a bamboo platform built on the shoreline or out at sea. They typically use kerosene lamps placed above the center of the net as fish attractors. The nets are lifted by means of counterweights, with the fish collected by long hand nets.
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. [1] Lift nets are also sometimes called "dip nets", though that term applies more accurately to hand nets. [2]
