If you ever watched National Geographic television and are interested fishes and rivers, you likely have some familiarity with Dr. Zeb Hogan. He hosted a series of shows on giant freshwater fishes, called Monster Fish. He and a colleague also recently published a fascinating book (Hogan and Lovgren 2023) on global adventures searching for giant freshwater fishes. This book is likely to interest California Water Blog readers for several reasons. Zeb obtained a PhD in Ecology from UC Davis working with Bernie May, Peter Moyle, and other faculty. His dissertation included a study of the biology and conservation of giant catfish in the Mekong River, documenting it was close to extinction. His new book discusses sturgeon conservation at length and provides additional background useful for saving the white and green sturgeon in California.
