This seven-volume series is the most extensive treatise on early life histories of the freshwater fishes of North America. It represents the state-of-the-art in fishery biology and provides a systematic approach to the study of early life histories of all the fishes in this region. Each volume contains distinguishing characteristics and a pictorial guide to the families of fishes in the OR Drainage, followed by chapters on the families. This series fills a gap in the literature, providing information on the spawning habitat requirements, reproductive behavior, and ecological relationships during the first few months of life for most species. This fifth volume examines the family Centrarchidae.

This series fills immense gaps in knowledge of issues related to early life development of fishes in the Ohio basin. Volume I includes familes Acipenseridae to Esocidae, Volume II includes the Catostomidae, while Volume III addresses the developmental and morphological issues of catfish and madtoms. This volume describes the characteristics of the Ictaluridae family, and provides a detailed pictorial guide. Subtopics within each species description includes range, distribution, occurrence, spawning, eggs, development, ecology of early life phases, and more. This book serves as both a ready guide to help identify individual larval fish, and as a reference for environmental managers concerned with the overall health of the ecosystem that they are monitoring.

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.
