I was out on the bayou (Louisiana) with graduate students today, collecting fishes for one of their projects. We were targeting Spotted Gars, but ran into an unusual abundance of Largemouth Bass. This got me thinking about “the most popular sport fish” in the USA: the Black Basses. Although many anglers and fish enthusiasts are familiar with Largemouth and Smallmouth Bass, there are actually several other species of Black Bass (genus Micropterus). Learn more about these other species in a guest post by Tim Bonvechio, edited by Patrick Cooney, with artwork by Hannah Dean – Black Bass: How Many Species Are There?
