One of the most dangerous jobs for child slaves is working on fishing boats. Seven days a week, 14 hours a day, the "fishing children" are ordered to risk their lives, Lisa says. Beginning each day at 4:30 a.m., the children—many of whom don't know how to swim—are forced to paddle long distances, dive into frigid waters and pull heavy fishing nets from lakes. Lisa says if all goes well, the children pull them up and collect the fish. "But sometimes the nets get caught, and that's when it becomes very, very dangerous," she says.
