Background

Aquatic invasive species (AIS) are non-native aquatic plants or animals that, once they invade an area, may compete with native species for food and habitat resources. They may threaten native species diversity or abundance and disrupt the ecological balance of the invaded area.

Aquatic invasive species have been entering Lake Huron and the Great Lakes at an increasing rate since the turn of the century. The Alpena FWCO actively monitors invasive benthic fish and educates the public about invasives that threaten the Great Lakes. The office is currently conducting activities targetting round goby and Eurasian ruffe. The office conducts annual surveillance efforts in nearshore areas of Lake Huron and the St. Marys River. Activities mainly target shipping ports and rivers to detect new populations of benthic invasive fish species and to monitor existing invasive fish populations. Surveys are mainly conducted using bottom trawling gear, however other forms of sampling gear may also be used. The station also provides fishery and habitat assistance with aquatic invasive species related issues.

AIS education is an important tool to alert water users about problems associated with non-native species. Educational efforts also help water users identify invaders and let them know what they can do to help deter or prevent their spread. The Alpena FWCO distributes educational materials including posters, identification cards, and brochures to bait and fishing license vendors. We also provide invasive species displays at public events and invasive species presentations for local conservation and school groups.
