Is transport stress limiting success of Bloater reintroduction in Lake Ontario?
Alex Gatch (USGS) presents his research on efforts to stocking bloater in Lake Ontario. He covers testing factors including temperature, handling, light, and exhaustion that contribute to overall stress and mortality during stocking events.
Lake Erie Cisco spatial unit assessment and delineation
An expert panel convened to delineate spatial units of Lake Erie Cisco. The panel determined that no viable Cisco populations remain in Lake Erie. Experts delineated one eastern and one western unoccupied Cisco spatial unit in Lake Erie based on interpretation of...

A tale of two species: long-term coregonine recruitment dynamics and drivers among the Great Lakes
Taylor Brown (Cornell), provides an in depth look at the variables potentially driving recruitment dynamics of the cisco and lake whitefish within…
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.
