Book excerpt: Chance Favors Only the Prepared Mind How does a scientist go about the task of pushing back the curtains of the unknown? Certainly the romance of tackling the mysteries of nature provides the motivation, for who would not be inspired by the remarkable life history of this romantic beast, the salmon. After living in the Pacific Ocean for several years, salmon swim thousands of kilometers back to the stream of their birth to spawn. I have always been fascinated by the homing migration of salmon. Noone who has seen a 20-kilogram salmon fling itself into the air repeatedly until it is exhausted in a vain effort to surmount a waterfall can fail to marvel at the strength of the instinct that draws the salmon upriver to the stream where it was born. But how does it find its way back? I was puzzling over this problem during a family vacation in 1946. Inspired by the work of the great German Nobel Laureates, Karl von Frisch and Konrad Lorenz, I had been conducting research with my graduate student Theodore Walker, since 1945, on the ability of fishes to discriminate odors emanating from aquatic plants. Von Frisch had studied schooling minnows and discovered that, if broken, their skin emitted a con specific chemical substance, termed Schreckstoff, which caused other members of its school to disperse and hide.

Available in PDF, EPUB and Kindle. Book excerpt: A Pulitzer Prize-winning correspondent and a former private investigator dive deep into the murky waters of the international salmon farming industry, exposing the unappetizing truth about a fish that is not as good for you as you have been told. A decade ago, farmed Atlantic salmon replaced tuna as the most popular fish on North America’s dinner tables. We are told salmon is healthy and environmentally friendly. The reality is disturbingly different. In Salmon Wars, investigative journalists Douglas Frantz and Catherine Collins bring readers to massive ocean feedlots where millions of salmon are crammed into parasite-plagued cages and fed a chemical-laced diet. The authors reveal the conditions inside hatcheries, where young salmon are treated like garbage, and at the farms that threaten our fragile coasts. They draw colorful portraits of characters, such as the big salmon farmer who poisoned his own backyard, the fly-fishing activist who risked everything to ban salmon farms in Puget Sound, and the American researcher driven out of Norway for raising the alarm about dangerous contaminants in the fish. Frantz and Collins document how the industrialization of Atlantic salmon threatens this keystone species, endangers our health and environment, and lines the pockets of our generation's version of Big Tobacco. And they show how it doesn't need to be this way. Just as Eric Schlosser’s Fast Food Nation forced a reckoning with the Big Mac, the vivid stories, scientific research, and high-stakes finance at the heart of Salmon Wars will inspire readers to make choices that protect our health and our planet.
