Deepwater cisco

The last specimens of deepwater ciscoes were recorded in Lake Huron in 1952 and Lake Michigan in 1951.

The Deepwater cisco lives in the demersal, freshwater environment.

The deepwater cisco (Coregonus johannae) was one of the largest ciscoes in the Great Lakes. Its average length was 30cm (12 inches) and it was about 1.0 kilogram (2.2 pounds) in weight. More

example, one species of deepwater cisco and one form of deepwater lake trout are being considered for reintroduction. These efforts, if they come to fruition, will likely stimulate enthusiasm for reintroducing other extirpated fishes. Such efforts will require a well-focused research agenda to help guide decision-making. More

The Deepwater Cisco was distinguished by usually having less than 33 gill rakers, relatively long pectoral fins, and unpigmented jaws. It was a silvery colour with a pink or purple lustre and a green or blue back. More
