Abstract: A fishing jig body capable of housing a chemiluminescent cartridge includes a channel in a lateral side of the jig body which allows the cartridge to pressed into a central chamber but is shorter than the cartridge such that the process causes the cartridge to flex and activate the luminescent material within. The jig body is made of a specific size and weight so that it will sink into deep water against currents to a empirically determined depth without the need for adding additional weight to the line or tackle attached to the jig body. Optionally, the jig body may have provision for attaching additional weight without significantly altering the overall shape or appearance of the jig body. Optionally, additional channels may be disposed in the jig body to allow light to escape from the chemiluminescent cartridge through other points on the jig body thereby highlighting features of the body, outlining it, or creating the appearance of appendages or fins.
