Fisherman in the northern Vietnamese province of Lao Cai earned up to $485 (10 Million Vietnamese Dong) a week through an illegal fishing process of using electrical shocks to kill fishes.
Between 2008 and 2011, the fisherman were buying 350-volt transformers for $145 (3 Million Vietnamese Dong) and putting the electrical devices in to the waters to kill fish. The device would send out electrical pulses up to seven meters that would either kill or stun fish.
There are about 200 people who are working in the illegal fishing industry in the province.
