St. Clair-Detroit River Burbot
Project Title
Movements of Burbot within the St. Clair-Detroit River System (Pilot Study)
Project Code
Project Duration
May 2017 - December 2020
Project Description
Great Lakes Burbot (Lota lota) experienced a population collapse in the early-to-mid 1900s associated with the establishment of invasive species, over-exploitation, and habitat degradation. With the implementation of sea lamprey (Petromyzon marinus) control programs and declines in alewife (Alosa pseudoharengus) abundance, many Great Lakes burbot populations are currently recovering. Population assessments have been conducted in the Great Lakes, though baseline information about the ecology within connecting channels is scant. Burbot in the St. Clair-Detroit River System (SCDRS), the connecting channel between lakes Huron and Erie, are showing signs of resurgence with collections of larvae, juveniles, and adults occurring in several different surveys conducted in various riverine habitats. To better understand movement patterns of burbot in the SCRDS corridor we initiated a pilot movement study during the spring of 2017. The purpose of this study is develop an understanding of the spatial and temporal movement patterns of burbot captured within the SCRDS.
