If you are fishing clear water for any species of fish you must match the forage of the body of the water. This is well painted jerkbaits and crankbaits can really do well. Also, life like swimbaits are a good options. If you are using spinnerbaits or chatterbaits you should use a more natural looking skirt with the proper blades to match. The same is true with crawfish. Depending on what part of the country and type of structure that you are fishing crawfish take on different color patterns. Knowing which pattern will lead to a higher success rate.
