Aquatic Native Species and Habitat Restoration: Cisco Spawning Habitat Assessment

Cisco (formerly known as Lake Herring) Coregonus artedi are native shallow water coregonines which were formerly very abundant in the Great Lakes and provided large commercial fisheries and healthy prey to native piscivores.  In most areas outside of Lake Superior, cisco abundance is greatly reduced and in Lakes Ontario and Erie they are uncommon to rare.

Aquatic Native Species and Habitat Restoration: Restoring native freshwater fish populations

USGS is working to help restore Atlantic salmon, bloater and cisco populations in Lake Ontario and the St. Lawrence River as part of the Coregonid Restoration effort. These three key species of the native Lake Ontario fish community are extirpated (Atlantic salmon and bloater) or are at low levels of former abundance (cisco).
