However, some spawning fish may defend their territories by striking a lure placed in their area. The catches of fish species which feed primarily by sight can be difficult when water visibility is less than two feet. Bait or lure selection, placement and action should approach the natural food organism of the species sought. Learn more about forage species such as crayfish or aquatic insects by turning over rocks in the water. Be persistent, vary your lures, colors and baits, keep them moving and do not spend more than 15 minutes in one location unless you are catching fish.
Fish vary in their ability to distinguish color, but most have some ability.
Red is the all-around most responsive color. Blue and purple are most visible in deep water. Combining an appeal to the taste, smell, feel and sight will increase the catch of any species. Fish in deep water look for food on their own visual plane or lower, whereas fish feeding near the surface tend to blend vertical and horizontal movement. Practice working lures in shallow water to observe their action.
