About Megafishes
Biologist Zeb Hogan leads the Megafishes Project, a three-year effort to document the 20-some species of freshwater fish at least 6.5 feet (2 meters) in length or 220 pounds (100 kilograms) in weight. These fish are losing the fight for survival, as pollution, overfishing, and construction threaten the rivers and lakes they call home.
