The Orinoco River – one of the longest in S. America, has tributaries and wetlands that spread throughout Venezuela and Colombia for hundreds of thousands of square miles. Among the most biodiverse ecosystems in the world and the native range for many aquarium fish species, the stability of the Orinoco basin and surrounding forests is under threat from a variety of natural and man-made challenges. My guest today, Ivan Mikolji, world-renowned naturalist, audio/visual artist, and author, returns to share stories from his new book, “Fishes of the Orinoco in the Wild.” Join us, as Ivan guides us through the stories, photographs, concerns, and hopes for a better future for this treasured natural resource.
