All avid anglers know fish are attracted to bubbles. If you are using a hollow plastic tube jig on your line, just break off a piece of Alka-Seltzer and slip it into the tube. The jig will produce an enticing stream of bubbles as it sinks.
None of your fancy fishing lures working? You can make one in a jiffy that just might do the trick: Wrap some aluminum foil around a fishhook. Fringe the foil so that it covers the hook and wiggles invitingly when you reel in the line.
A cork makes a great substitute fishing bobber. Drive a staple into the top of the cork, then pull the staple out just a bit so you can slide your fishing line through it.
Pack a can of cooking spray when you go fishing. Spray it on your fishing line and the line will cast easier and farther.
Salmon fishermen in the Pacific Northwest spray their lures with WD-40 because it attracts fish and disguises the human odor that can scare them off and keep them from biting. You can increase the catch on your next fishing trip by bringing a can of WD-40 along with you and spraying it on your lures or live bait before you cast. But first check local regulations to make sure the use of chemical-laced lures and bait is legal in your state.
