Lake Ontario Deepwater Cisco
Project Title
Post-stocking behaviour, distribution and survival of deepwater cisco in eastern Lake Ontario
Project Code
LODWC
Project Duration
November 2015 - December 2020
Project Description
Based on recently developed and successfully-tested surgical methods, we implanted V7 and V9 acoustic tags into 70 juvenile Bloater (Coregonus hoyi) and released them in eastern Lake Ontario in Nov 2015 as part of a normal stocking event (n=32,000 fish). A network of 80 acoustic receivers encircling a deep water channel will be used to measure their behaviour, dispersal, habitat use, and survival. In 2016, we expanded the array (n=104 receivers) and stocked additional Bloater in November with both traditional V9 tags and V9-pt tags. In the spring of 2017, we released additional Bloater using both types of V9 tags. With additional funding received from the GLFC and other sources and partners in 2017, we will continue to inform Bloater restoration initiatives using acoustic telemetry including collecting extensive physical, chemical and biological data in and around our array needed to inform behaviour and survival analyses.
