Application of a data-limited stock assessment model to understand the historical population of cisco in Lake Erie
Lee et al. have applied a data-limited model to historic records of commercial catch combined with some basic life history information to estimate the population size of cisco in Lake Erie prior to the collapse of the fishery in the early 20th century. The model uses...
Cisco Stocking in Lake Erie – NYS Department of Environmental Conservation
This spring, DEC in cooperation with the U.S. Fish and Wildlife Service, began a ten-year experimental reintroduction of cisco into the New York portion of Lake Erie to determine if they can survive to adulthood in the lake as it exists today. The initial stocking of 90,000 yearlings this May occurred offshore of Dunkirk, NY. The results of this work will help inform future cisco rehabilitation decisions in New York and elsewhere.

Challenges in producing fish in hatcheries for restoration efforts
Trevor Pitcher from the University of Windsor explains his research regarding the challenges of producing fish in hatcheries, from gamete quality to transport stress. He teaches us the history and future of fish hatcheries and reintroduction programs.
Using telemetry to study Cisco movement and behavior in Lakes Superior and Ontario
Kyle Stratton of OMNR and Alex Gatch of USGS give subsequent presentations about behaviors of ciscoes in Lakes Superior and Ontario. They will talk about challenges with these fish, tagging in the winter, and what the telemetry data tells us.
