Abstract: A jugfishing apparatus and signaling device for indicating to a jugfisherman that a fish has struck the bait. The signaling device can include an illumination device such as a light bulb, or an audible signal. When a fish strikes the bait, the signaling device is activated and remains so until de-activated by the fisherman. The force necessary to trigger the signaling device can be adjusted along a continuous range for a variety of fishing conditions, to implement different fishing tactics, and to allow the use of any of a number of standard-size buoyant containers.
