Bass are delicate to scent, so any chemicals or scents on the angler's hands, or when taking care of the rod, reel, or bait, can inform the bass of the angler's presence. For instance, bass can smell chemicals such as insect repellent, or tobacco. The fragrance of the chemicals is transmitted to the line, rods, reels, and also lure, specifically if soft plastics are used as bait.
The development of bass fishing was progressed by the development of the railway. Initially, railroads ran steam engines that needed water for the vapor. Pools were produced by damming creeks that intersected near the railroad tracks. It was located that bass could possibly be transferred in barrels or buckets through the railroad. So both largemouth as well as smallmouth bass were moved throughout the nation.
