Making sense of piscatorial senses: sight, sound, smell, and taste

Attend one of my seminars during the hard water season, and you’ll hear me emphasize the need for controlling odors and noise. Combined with the appearance of our presentation, these are arguably the most important keys to any productive presentation.

For starters, I can’t overstate the importance of managing odors while we’re fishing. Rough fish and game fish alike sense odors in a way that we humans, with our relatively poor ability to smell, can’t begin to understand. Use this knowledge to your advantage by providing scents that fish associate with natural prey while managing the unnatural odors that repel fish!

Anything remotely unnatural to our better judgment and remedial senses – like gasoline, tobacco, exhaust fumes, even highly processed food – will alert and/or discourage fish from approaching our bait and lures. Fish have a keen sense of smell, and they won’t take (or hold) your bait if it doesn’t pass the smell test. I use one pair of gloves for preparing to fish in winter and one pair for my actual fishing.

Sights and sounds stimulate the most important senses in almost all creatures: vision and hearing. Tempting walleyes and other gamefish with strong or sometimes subtle auditory or visual stimuli will prompt bites, even with neutral or – no kidding – negative fish. Once they recognize the stimuli, in my experience, increasing the pulse or action will arouse even more interest in the species you’re pursuing.

Remember that sound travels faster underwater than through air, and it travels even faster in the denser, colder water of winter. Work that in your favor with rattle and vibrating lures, but prevent it from becoming a negative factor by keeping noise to a minimum above the ice.

Expect the ice and water to amplify even small sounds underwater, so avoid slamming skimmers on the ice, and map out and drill your ice holes in one clean, efficient round.

Sight, sound, scent all lead to the final test for a fish considering your offering: taste. If the end of your line feels wrong or delivers an unfavorable taste, sportfish will blow out or otherwise expel lures in fractions of a second.

Tests and high-speed photography work with crappies has shown they can taste, recognize, and reject unsatisfactory bait or lures in less than half a second. If you’re using plastics or other artificials, be prepared for fast hooksets!

Good luck out there during this midwinter period!
