"Henry David Thoreau wrote, ''Who hears the fishes when they cry?'' Maybe we need to go down to the river bank and try to listen."In what he says is the most important piece of environmental writing in his long and award-winning career, Mark Kurlansky, best-selling author of Salt and Cod, The Big Oyster, 1968, and Milk, among many others, employs his signature multi-century storytelling and compelling attention to detail to chronicle the harrowing yet awe-inspiring life cycle of salmon.

During his research Kurlansky traveled widely and observed salmon and those who both pursue and protect them in the Pacific and the Atlantic, in Ireland, Norway, Iceland, Japan, and even the robust but not as frequently visited Kamchatka Peninsula. This world tour reveals an eras-long history of man’s misdirected attempts to manipulate salmon and its environments for his own benefit and gain, whether for entertainment or to harvest food.

In addition, Kurlansky’s research shows that all over the world these fish, uniquely connected to both marine and terrestrial ecology as well as fresh and salt water, are a natural barometer for the health of the planet. He documents that for centuries man’s greatest assaults on nature, from overfishing to dams, from hatcheries to fish farms, from industrial pollution to the ravages of climate change, are evidenced in the sensitive life cycle of salmon.

With stunning historical and contemporary photographs and illustrations throughout, Kurlansky’s insightful conclusion is that the only way to save salmon is to save the planet and, at the same time, the only way to save the planet is to save the mighty, heroic salmon.
