The headline of this article from The Baltimore Sun says it all: "Goldfish become occupying force." Seems hundreds of goldfish (Cyprinus auratus), along with a few big koi (Cyprinus carpio) have taken over a pond in Columbia, Maryland, leading to a distinct lack of amphibians in the area. One "solution" being considered is to stock the pond with bass, who will eat the goldfish, and bluegills, to eat insects and provide an additional food source for the bass (!!), and then keep the bass under control by allowing fishing. Another possible solution: Stop dumping your unwanted pets!
