For the final episode of 2025 The Fisheries Podcast brings you an absolutely delightful conversation between Brendan and Dr. Nicholas Mandrak of the University of Toronto Scarborough on binomial nomenclature, the Committee on Names of Fishes, and most importantly, how and why fish get and keep and or change their scientific and or common names! Dr. Mandrak is a legendary scientist in Canadian circles, having co-authored over 250 primary publications, over 100 government reports, 40 COSEWIC reports, and five books, including the newly revised Royal Ontario Museum Field Guide to Ontario Fishes. He is Program Director of the Conservation and Biodiversity stream of the professional M.Env.Sci. program at UTSC. Nick is also a Research Associate of the Royal Ontario Museum and South African Institute of Aquatic Biodiversity.
