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. Ecology of Salmonids in Estuaries Around the World, 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 over 1,000 scientific papers and reports, including data from 196 estuaries in the northern and southern hemispheres, to:
- describe the specific adaptation of eighteen anadromous salmonids in four genera (Hucho, Oncorhynchus, Salmo, and Salvenlinus),
- explain the ecological relationship between anadromous salmonids, the fish they co-exist with, and their estuarine habit
- discuss key fitness elements salmonids need for survival, (including those relating to osmoregulation, growth and feeding mechanisms, and biotic interactions),
- provide guidance on how to conduct estuarine sampling, including a discussion of various methods used by scientists around the world
- discuss scientific aspects of management plans that emphasize recovery of habitats and ecological integrity and resilience,
- and offer directions for future research to advance the study of estuarine salmonid ecology.
This long-overdue reference book is further enhanced by extensive supplementary appendices that are available to readers online.
