About This Species

Oriental weatherfish, also known as Weather loach, Pond loach, or Dojo, is an eel-like freshwater fish. They are a widespread invasive species in North American freshwater systems, and are found in the Alouette River system in BC.

Oriental weatherfish feed on aquatic insects, and compete with native fish for food, habitat, and spawning sites. They is a very hardy fish, capable of living in waters ranging between temperatures of 2-30 °C, and able to breathe air when in low-oxygen environments. During droughts, this fish buries itself in mud and can survive for up to three months without feeding.
