Giant Catfish Spared From Fishing on Cambodia River

On Cambodia's Tonle Sap River, conservationist Zeb Hogan is hoping to save the giant catfish, the largest freshwater fish in the world, one fish at a time.

If fishers here catch the critically endangered species, which can grow up to 10 feet (3 meters) long and weigh 650 pounds (295 kilograms), they now must turn it over to Hogan, who heads the Mekong Fish Conservation Project.
