From Pet to Pest: Don't Release Those Goldfish!
Recent study finds released goldfish have massive impact on lakes. Water quality declined rapidly as goldfish churned up bottom sediments which clouded the water and increasing suspended particles. Populations of snails, amphipods and zooplankton fell sharply as goldfish consumed prey and destroyed habitat.
“Releasing a goldfish into the wild may feel like an act of kindness, but it can quickly become a major ecological threat.” - William Hintz, University of Toledo
Never release pets into the environment.
