  • Signalling means for a crustacean trap
    Patent number: 4373288
    Abstract: The invention, according to the depicted embodiment, comprises a buoyant element which is releaseably held atop a crustacean trap by an elongate rod. One end of the rod releaseably engages the buoyant element, and the other end thereof is passed through the trap and suspends bait therewithin. Upon a crustacean seizing the bait, and attempting to remove it from the rod, the latter comes free of the buoyant element which, in turn, rises to surface upon the water. In the preferred embodiment depicted, the buoyant element is tethered to the crustacean trap for recovery purposes.
