Of the 175+ aquatic invasive species and non-indigenous aquatic species with resident populations in the Great Lakes, about 41% of them are animals, ranging from the very damaging sea lamprey to zooplankton such as the fishhook waterflea and such sought after introduced gamefish as the mighty chinook salmon, and a handful of insects. Although zebra mussels are also aquatic invasive animals, their significance has qualified them for their own page withing this website.
Fact Sheets
Guidelines for Reducing the Spread of "Fishhook Waterfleas" (Cercopagis pengoi) D MacNeill, M Snyder, K Schultz and J Makarewicz. 2004. 4 pp.
The "fishhook waterflea" (Cercopagis pengoi), a predatory zooplanktor which preys on smaller zooplankton, has invaded Lake Ontario and six of New York's Finger Lakes. This species of invasive animal can easily be spread on fishing gear and fisheries sampling equipment. This 4 page factsheet gives an overview of the species' biology and life cycle, its invasiveness, and recommendations on methods to prevent it wider spread throughout North American waterbodies.
