Invasive Giant Goldfish Threaten Great Lakes Ecosystem

A study published in the Journal of Great Lakes Research has found that millions of goldfish are wreaking havoc in the Great Lakes, with the potential to grow up to 16 inches and weigh over 5 pounds. The increase in goldfish population has coincided with a decrease in the carp population, posing a threat to native fish species. Goldfish, originally from Asia, were introduced to the Great Lakes in the 1990s and are now thriving due to their ability to survive in extreme environments. The study highlights the need for alternate control measures to protect native fish habitats and prevent further invasion into new areas.
