How does the lateral line help a muskie track a lure?
The lateral line reads pressure waves and water displacement, giving the fish a touch-at-a-distance sense that works in the dark and in water too murky for eyes. A muskie shadowing a bait is often holding in the lure's wake, sampling its pressure signature — which is why a bait that "moves water" (big blades, wide-wobbling rubber, tail-kicking swimbaits) draws fish from farther away than a quiet one. The lateral line is also how a night-feeding muskie times the final strike on a bait it can barely see. Every lure choice is really a choice about what pressure signal you are broadcasting.
