Researchers confirmed the presence of fishhook waterflea (Cercopagis pengoi) in Lake Champlain, bringing the known number of nonnative and aquatic invasive species in Lake Champlain to 51. The fishhook waterflea is similar to the spiny waterflea, which was confirmed in Lake Champlain in 2014; they are both small crustaceans that are aggressive predators of zooplankton and are known to foul fishing lines.
