Daniel Bagur 
Where the Fish Are 
A Science-Based Guide to Stalking Freshwater Fish

More science and less art leads to bigger fish and fewer tales Most anglers rely on advice from fishing buddies or books by well-known but unscientific anglers. Here is a book that distills the science of fish behavior into easy-to-follow advice on how to catch fish in any situation. Describing how feeding behavior in fish changes in response to fluctuations in dissolved oxygen, turbulence, turbidity, temperature, light, noise, and other factors, Bagur advises you on how to respond, recommending specific flies, baits, rigs and tactics.
