R3 Digital Sciences developed the Fish Trap Extension Kit (FTEK), an electromechanical device that is able to extend the capabilities of existing fish traps and convert them from indiscriminate traps into “smart traps” capable of targeting specific fish types. To eliminate lionfish bycatch, the FTEK enables existing commercial spiney lobster traps to autonomously detect, discriminate, and capture lionfish, while preventing other animals from entering the trap. In addition, the FTEK detects anomalous trap conditions and is able to render traps inert by permanently closing the trap entrance. Thereby eliminating the ghost fishing problems associated with conventional fish traps.
