How are Asian carp getting into the Great Lakes?



  1. 0 Votes

    Asian carp have been present in the Great Lakes since the 1990’s, but their numbers are only increasing due to reproduction. Two Asian carp species, Bighead and Silver, were introduced into the Lake when catfish farmers used them to remove algae from their ponds. During large floods in the early 1990s, many of the catfish farm ponds overflowed their banks, and the Asian carp were released into waterways that lead directly into the Lakes.
