Nearly all fresh water game fish as well as saltwater fish are attracted by underwater lights. Colored lights quickly concentrate such fresh water fish as walleyed pike, black bass, crappies, northern pike, bluegills, perch, stream and lake trout and practically all salt water fish including tarpon, yellowtail, striped bass, grouper, snook, sailfish and marlin…

The theory behind this is quite simple. A submerged light stimulates the natural food chain by attracting a concentration of tiny organisms called zooplankton. Smaller ‘bait’ fish such as minnows and shad are attracted by the light and concentrated food source, which in turn attracts the larger fish.

Green, yellow, orange, and red lights work like magic. White lights not at all or very poorly. In order to get light under water you must use a gas and waterproof type of electric light fixture such as used in showers or in paint spray booths. The cord letting the light down into the water must be waterproof rubberized cord and all connections to the fixture must be carefully covered with waterproof rubber tape. You can use batteries or a small generator for the power source in your boat.

Japanese commercial fishermen now use underwater colored lights almost entirely to attract and congregate salt water fish of all kinds including salmon in areas for netting.

Fishing ‘bait’ lights are being sold by sites such as baitlight.com, Evening Secret, and others.
