An Investigation into the Ecological Costs of Sea Lamprey Control on Lake Sturgeon and Ammocoete Predators using Olfactory Techniques, Kathy Sakamoto

Fish that feed or travel in low light conditions particularly rely on their chemical senses, such as olfaction, for survival. Exposure to toxicants at concentrations lower than those causing mortality can have detrimental effects on olfactory senses. Kathy's research studied sea lamprey control from two ecological perspectives. The first was to determine if the lampricide 3-trifluoromethyl-4-nitrophenol (TFM) affects the olfactory capabilities and behaviour of young-of-the-year (YOY) lake sturgeon (Acipenser fulvescens) and reduces food consumption. The second part investigated the attraction of aquatic organisms to the scent of lamprey ammocoetes (larvae) as a food source.

Resolute Forest Products' recently updated Species at Risk and Invasive Species Handbook - Dr. Ashley Thomson

Dr. Ashley Thomson, Forest Ecologist, will present Resolute Forest Products' recently updated Species at Risk and Invasive Species Handbook. The Handbook is a field reference used to train and direct Resolute's forest workers and contractors on how to identify, manage and report species at risk and invasive species sightings. Feedback and suggestions from TBFN members are welcomed and will be used to improve subsequent versions of the handbook and other species at risk/invasive species training tools.
