Salmon

The life cycle of the salmon is a remarkable story of survival. Their amazing feat of migration from freshwater streams to saltwater oceans, and back again, is surely one of the great wonders and mysteries of the natural world. John Baxter uncovers, the origins, migratory instincts and life histories of all seven salmon species found around the world. He explores the many conservation issues facing salmon today, with populations suffering sharp declines due to pollution, overfishing and changes to river habitats.
