Book excerpt: This series fills immense gaps in knowledge of issues related to early life development of fishes in the Ohio basin. 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 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.
