Biologists have long marveled at how anadramous salmonids - fish that pass from rivers to oceans and back - survive as they migrate between these two very different environments. Yet, relatively little is understood about what happens to salmonids in the estuaries where they make this transition from fresh to salt water as young fish and make the reverse migrations as adults. Based on his recent book published by UBC Press, Coling Levings will present an overview of our current knowledge of how salmonid species around the world (including salmon, steelhead, char and trout) are adapted to estuaries. Anadramous salmonids are expanding their world range and are now found on all continents except Africa and Antartica. He will also discuss the wide diversity of estuary types found on various continents as well as the estuarine habitats used by salmonids. His review of the world literature found that as our knowledge of estuaries and salmonids expands, researchers are realizing the important linkages between rivers, estuaries and the oceans.
Dr. Levings works at the Fisheries and Oceans Canada (DFO) lab in West Vancouver, now as a Scientist Emeritus. His is also an adjunct Faculty Member in the Insititute for Resources, Environments and Sustainability at UBC.
