Bay of Quinte Cisco and Lake Whitefish
Project Title
Investigating the movements of Cisco (Coregonus artedi) and Lake Whitefish (Coregonus clupeaformis) within the Bay of Quinte, Lake Ontario
Project Code
Project Duration
April 2016 - March 2025
Project Description
The Cisco/Lake Herring (Coregonus artedi) is a cold-water planktivorous fish species that has undergone significant declines throughout the Great Lakes. This decline has been associated with a number of factors, with the most influential being the degradation of important habitat, past commercial exploitation, and the introduction of various invasive species. Although environmental agencies have expressed a growing interest in the rehabilitation of Cisco within this region, lack of basic natural history knowledge of many Great Lake Cisco populations has prevented most recovery efforts. This study will attempt to increase our understanding of Cisco movement dynamics within the Lake Ontario ecosystem, with a particular focus on seasonal migration and spawning behaviour of Cisco inhabiting the Bay of Quinte. As a secondary objective, this study will also be used to gain information on the Lake Whitefish (Coregonus clupeaformis), a cold-water benthopelagic species that has also experienced declines within the Great Lakes system. We have implanted a total of 30 Cisco and 29 Lake Whitefish for this study, and are monitoring their movement using an existing acoustic telemetry framework (see ELOBB).
