Zeb Hogan is a researcher at the University of Nevada, Reno, a National Geographic Fellow and the United Nations Convention on Migratory Species Scientific Councilor for Fish. Hogan also hosts the popular National Geographic Television series Monster Fish.
Hogan’s research focuses on migratory fish ecology, multi-species fisheries management, the status and conservation of giant freshwater fish, endangered species issues and conservation genetics. He leads the National Geographic Society’s Megafishes Project, a multi-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. Around the world, freshwater ecosystems support tens of thousands of unique species and hundreds of millions of people. Through the Megafishes Project, Hogan travels to the most endangered of these environments, striving to save critically endangered fish and the livelihood of people who share their habitats. His travels are chronicled through the Monster Fish series.
Hogan, who has a doctoral degree in ecology, was a visiting Fulbright scholar at the Environmental Risk Assessment Program at Thailand’s Chiang Mai University and has served as a World Wildlife Fund senior freshwater fellow. His work has spanned six continents and encompasses several of Earth’s most diverse freshwater ecosystems including World Heritage Sites, Ramsar Wetlands of International Importance and United Nations Environment Program Biodiversity Hotspots. Other sites studied include the Amazon River, Mekong River, Mississippi River, Nile, Lake Baikal watershed in Russia, Murray-Darling River in Australia, tributaries of the Danube and Yangtze River in China.
