Fish liftnet

              This gear is a modification of the crab liftnet.  The metal frame is round, 50-80 cm in diameter, and contains a 1 m deep nylon net that looks like a scoop net, with 25 mm mesh size.  A rope is attached to the frame, for lifting the gear to the surface.  Before the net is lowered to the bottom, a small piece of fish or crab is hung in the center of the frame as bait.  The net is lifted frequently to check if there is catch, which may be a rabbit fish, marine catfish and sometimes a young grouper.  One often sees this gear used by children or occasional fishermen, in fishing ports.

              A kind of fish lifenet is used for catching planktonic shrimp.  The net in this case is either cotton, nylon or polyethylene minnow or rachel net, mesh size 2 x 2 mm or 6-8 mm.  A bamboo handle, 2-3 m long, is commonly used for gear with a square frame, whereas a round frame has a rope attached for lifting.  The net is operated so that it is placed at the bottom in very shallow water, and the fisherman waits until he sees a school of planktonic shrimp pass; then he lifts the net.  No bait is required.
