A submersible lantern is anchored to the sea floor and kept upright by a float and a countersink weight. The lantern emits multiple patterns of green and white light at specific frequencies and intensities that repel catfish while causing shrimp to surface. The lantern has an elongated body, and includes a float and weight to vertically orient the lantern underwater so that it emits light 360 degrees around the lantern body. A push button switch along with a PCB board cycles the lights and power level to the lights based on the particular application. A wireless circuit is used for remote operation via a mobile phone or other wireless device. The lantern can be used both in the sea and on land, and includes a two-part power connector to connect to various conventional power sources.
