Fiskarnas rike S02E01 - Vattnets kraft

Many fish need running water to reproduce. But in rivers and streams they are often met by hydroelectric dams and other obstacles that we humans have built. Martin Falklind explores the possibilities of helping the fish to migrate freely. We also meet Sweden's first inhabitants after the ice sheet, the char, and meet 12-year-old Edvin who does everything he can to help the fishermen.
