Living in a liquid environment, fish do not “smell” odors the way people do by inhaling air. “Like humans, fish have distinct systems for tasting and smelling,” said Dr. John Caprio, a world-renowned fish neurobiologist at Louisiana State University. “Humans smell things that go through the air. Fish can’t detect odors in the air. They detect water-soluble chemicals.” Dr. Caprio actually isolated the natural chemicals that stimulate fish to feed and put them into lures.

Slicing through the Ozark Mountains, the White River flows 720 miles from its headwaters to the Mississippi River in southeastern Arkansas. Near Mountain Home, Ark., it emerges from the dam at Bull Shoals Reservoir. Frigid water coming off the bottom of the lake turned the White River into one of the top trophy trout streams in the country. It produced brown trout exceeding 33 pounds and abundant rainbow trout up to 19 pounds.

In states where it’s legal, sportsmen enjoy “jugging” for catfish. Jugging involves attaching a baited line to a float, commonly a sport drink bottle or other buoyant object. On the jug neck or handle, tie heavy twine or braided fishing line, up to 200-pound test and attach a hook. Bait the hook and toss the jug into the water. As a catfish takes the bait, the jug starts bobbing. Some anglers use several dozen floats that could stretch a mile or more along a stream or lake cove.

Some professional bass fishermen add radar units to their fishing boats to help them navigate. Some electronics units can now display radar imagery with the right software and antenna connections. During the 2011 Bassmaster Classic in New Orleans, Gary Klein, a Texas bass pro, ran more than 110 miles one way to fish the Mississippi River delta, despite extremely foggy conditions. “When I was running in the fog, I still had a clear field of vision with the radar,” Klein said. “I was able to run in dense fog, knowing that my path of travel was clear.”

Off the Pacific Coast from Baja California to parts of Alaska, forests of giant kelp provide great habitat for hundreds of fish species. Some kelp grows more than 100 feet tall, forming a “living reef” of gigantic seaweed. Individual plants might grow more than a foot a day. Some fish that anglers catch around kelp forests include bonito, Calico bass, yellow tail, white sea bass, mackerel, rainbow runner, dolphin, halibut and many other species.
