Bob Muller's interest in fishes began in elementary school with the gift of a bowl of guppies. In High School, he has an aquarium of tropical fishes but, when he discovered the book 'Fishes of the Great Lakes Region' by Hubbs and Lager, in the school library, he began collecting fishes from local lakes and streams. He spent years learning to return these fishes to breeding condition and getting them to spawn while in captivity. Bob shares his breeding knowledge freely, authoring articles for American Currents, the magazine of the North American Native Fishes Association (NANFA). In 2013, he and Philip Kukulski, his partner in the Rouge Survey, discovered Dusky Darter (Percina sierra), a North American native fish unknown in Michigan, in two tributaries of the Maumee River in southern Michigan. He has sampled fishes from the Atlantic Ocean to the Great Plains and from our northern border to the Gulf of Mexico. Two trips to the Peruvian Amazon have been made collecting and studying fishes. A life long naturalist, he has always had an interest in how all the species interact in the environment. The Peru trips opened his eyes to these interactions in the fish community. Books on tropical fishes never explain which species live together in the wild, but in the field this is easily seen. Trying to understand these interactions of the species is a never ending process. For the last 12 years on the Rouge River this has been one of the driving reasons for sampling the entire watershed. Determining who is in the fish community, where, why and how they interact with each other.
