River Monsters: Season 2, Episode 6

2 - 6: Rift Valley Killers

Jeremy Wade is on a quest to Africa's Rift Valley to explore the roots of fishing and the monsters these first fishermen faced. It's a dangerous place, filled with killer crocs, hippos and warring gangs, but at its heart is a worthy prize: the Mputa, aka Nile perch, Africa's largest freshwater fish.
