Evolution
After awhile of fishing the angler realizes that he or she can do or must do more to increase his or her catch. From the basic form of bottom fishing evolution sets in now. To detect bites some anglers use tricks such as creating a slack line between a section of guides and hanging something there such as bread, straw, paper, etc. This acts as a bite detector. When the fish takes the bait, the bread, paper, straw, etc. goes up as the line straightens.
