Giant Goldfish Caught in South Carolina A survey of the fish population in a South Carolina lake led to the discovery of a monstrous nine-pound goldfish that had taken up residence at the site. The giant creature was reportedly found on Monday in Oak Grove Lake which is located in the city of Chesapeake. As part of a study of the location, a specialist conducted a test known as electrofishing, wherein all of the creatures living in the lake were stunned by a brief burst of electricity which does not harm them, but briefly sends them floating to the surface of the water. As the expert was documenting the fish population in Oak Grove Lake, he was stunned to see one particular creature standing out among the other jolted denizens of the site: a huge goldfish. Upon closer examining, it was found that the animal weighed a whopping nine pounds. Since goldfish are not native to the area, it is presumed that the creature was once a pet which somehow wound up in the lake. Fortunately the mighty fish was allowed to remain living in the lake, after a few photos of it were taken, since it is not an invasive species.
