Author Interview - Ecology of Salmonids in Estuaries around the World
For centuries, biologists have marvelled at how anadromous salmonids – fish that pass from rivers into oceans and back again – survive as they migrate between these two very different environments. Yet, relatively little is understood about what happens to salmonid species (including salmon, steelhead, char, and trout) in the estuaries where they make this transition from fresh to saltwater. This book, written by one of the world’s foremost experts on the ecology of salmonids, explains the critical role estuaries play in salmonid survival and recovery.
Ecology of Salmonids in Estuaries around the World synthesizes information from a vast array of literature, to
– describe the specific adaptation of eighteen anadromous salmonids in four genera (Hucho, Oncorhynchus, Salmo, and Salvelinus)
– explain the ecological relationships between anadromous salmonids, the fish they coexist with, and their estuarine habitat
– discuss key fitness elements salmonids need for survival in estuaries (including those relating to osmoregulation, growth and feeding mechanisms, and biotic interactions)
– provide guidance on how to conduct estuarine sampling and scientific aspects of conservation, management, and recovery plans
– offer directions for future research.
This critical reference is further enhanced by extensive supplementary appendices that are available to readers online, including data tables, additional references on estuarine salmonids, and a primer on estuaries and salmonids for citizen scientists.

"Colin Levings interweaves his vast scientific knowledge with history, and even ancient literature, to present an exceedingly insightful accounting of the estuarine life of salmonids around the world. This superb work will be of value to anyone interested in the ecology and conservation of estuaries."
