Offer the right bait, lure, or fly in the right place at the right time.

An impressive body of scientific research shows how fish respond to daily and seasonal changes in weather, light, temperature, and food availability and how they react to color, shape, movement, scent, and sound. These behaviors determine not only where you find fish but when and what they will eat once you find them. Now, for the first time, fisheries biologist and angler Daniel Bagur has distilled the scientific research into easy-to-follow advice on how to find and catch fish, including:

• Where and when gamefish gather
• How they use their senses to detect food and avoid predators
• How feeding behavior changes in response to fluctuations in turbulence, temperature, light, and noise
• How you can target these behaviors with flies, rigs, and tactics that catch more and bigger bass, trout, and other freshwater and saltwater fish
