Knowledge of the early life stages of fishes is crucial for the effective monitoring and management of fish populations and habitats, and the evaluation of environmental impacts and recovery of endangered species. Unfortunately, the proper identification of targeted species has stunted the development of the field. Now a series has emerged that stands as the leading resource on the reproduction and development of many North American fishes."Reproductive Biology and Early Life History of Fishes in the Ohio River Drainage" fills immense gaps in knowledge of issues related to early life development of fishes in the Ohio Basin. Volume 4 addresses the developmental and morphological issues of Perch, Pikeperch, and Darters. This volume describes the characteristics of the family Percidae, and provides a detailed pictorial guide to the young of all fish families present in the Ohio River drainage. Subtopics within each species description include range, distribution, occurrence, spawning, eggs, development, ecology of early life phases, and more. This book serves as both a handbook to help identify individual larval fish, and as a reference for those concerned with the overall health of the ecosystems or fisheries that they are monitoring.
