Species that are considered uncertain risk need a more in-depth assessment beyond the Risk Summary to better define the species’ risk to U.S. environments. This additional information will help inform decisions on where, when, and how the species may be used to minimize risks of them becoming invasive.
Corydoras aeneus is a small catfish native to South America and popular in the pet industry. This species has become established on two islands in Hawaii after introduction in the 1980s. Little information is available on what, if any, effects C. aeneus is having on native species in Hawaii. There is some evidence that along with other non-native consumers, C. aeneus is changing the trophic structure structure
Something temporarily or permanently constructed, built, or placed; and constructed of natural or manufactured parts including, but not limited to, a building, shed, cabin, porch, bridge, walkway, stair steps, sign, landing, platform, dock, rack, fence, telecommunication device, antennae, fish cleaning table, satellite dish/mount, or well head.
