| Impact Description | Aggressive round gobies probably drive a guarding male mottled sculpin off its nest and eat its eggs or YOY. Evidence from our studies suggests that this may be the case, since the one large mottled sculpin we had
with a number of round gobies was always sitting on top of a rock in the aquarium. |
