Fishes of South Dakota by Reeve M. Bailey and Marvin O. Allum provides a comprehensive survey of the fish species found in South Dakota. The book aims to collect and identify published records of South Dakota fishes, present keys for fish identification, record original distributional data based on numerous fish collections, address systematic status issues of certain species, clarify or extend information on species distribution in the adjoining Plains area, and interpret routes of postglacial dispersal. The authors also acknowledge the contributions of various individuals and institutions in their research. The study documents 93 fish species in the state, detailing their geographic sources and human impacts on their distribution, such as introductions and modifications due to agriculture and urbanization. The book includes detailed methods, maps, and an extensive collection of data and historical records, making it a significant contribution to ichthyological studies in the northern Plains region.
