Giant Goldfish found in Lake Tahoe
Researchers looking into the invasion of non-native species in Lake Tahoe were shocked to discover a huge goldfish as they trawled the lake. Found in a quiet corner of the lake, which lies on the border of California and Nevada the goldfish is one of around 16 so far discovered that are thought to have been dumped in the lake by an aquarium owner. When studied by University of Nevada researchers the fish was revealed to weigh 4.2 pounds and measured 1.5 feet; the goldfish is larger than the biggest recorded pet goldfish measuring fifteen inches and weighing just two pounds.
Aquarium dumping is thought to be the only way the goldfish could have made the journey into Lake Tahoe; as the trade in tropical fish, animals and plants increases the problem with non-native fish invading global waters is said to be increasing. In a recent survey of aquarium owners in Texas more than 20 percent of those surveyed admitted to dumping fish in the waters of the state.
Researchers fear a buildup of invasive species, such as the goldfish will cause dramatic losses of native fish and aquatic wildlife. Many non-native fish can feed on native wildlife removing them completely from a lake or take food away from native fish causing a reduction in species size. The large goldfish was one of a number found in a corner of Lake Tahoe leading researchers to believe the goldfish are spawning and breeding in the lake, which could lead to a large rise on the number of the fish found in the lake.
