CANADA: The Teller Lake near Valmont Road in Boulder County, Colorado is invaded by more than 4,000 gold fishes.
According to Colorado Parks and Wildlife (CPW) experts say few years ago an individual has dropped few fishes in the lake and over the time offspring’s of the goldfish exploded in the region.
Experts claim that these goldfish are not native to the lake and they may pose great threat to the ecosystem and biodiversity of the lake.
Other species found in the lake are tiger muskies, catfish, bluegills.
Tiger muskies are also not native to the lake but they are controlling the population of suckers in the lake ecosystem there by maintaining harmony. Hence they are not posing any threat to the lake ecosystem like goldfish.
