•Moveable rampani net
Fish poison

10-15 minutes.
Water explosions also kill the fish in large numbers. These
methods are not used in commercial fishery as all the fish are
killed indiscriminately.
Electric fishing
 It is new technique has been developed by using
low voltage electric current.
 The fish always swim towards the positive pole
