A press release from the Great Lakes Fishery Commission details new research that may lead to an effective control for the invasive round goby (Apollonia (Neogobius) melanostomus). According to the release, scientists have discovered that scent cues successfully attract female round gobies to traps. What scent, you ask, can pull a round goby away from her other activities deep in the Great Lakes? Male goby urine. The scientists are hoping further studies will reveal a way to set traps using the urine, allowing them to potentially disrupt the breeding cycle of these invasive fish.
