Chain pickerel (Esox niger) is a widely introduced fish species in Nova Scotia lakes. It is an aggressive ambush predator which will consume a wide variety of food ranging from dragonfly larvae to fish to frogs. Small mammals, birds and turtles have even been found in chain pickerel stomachs! Chain pickerel is associated with significant declines in diverse fish and amphibian populations and will impact native sport fisheries.
Our work looks how chain pickerel may be affecting contaminant transfer and vulnerable species in many lakes across Nova Scotia and New Brunswick. We are using stable isotopes of nitrogen and carbon and mercury analyses to analyse food web structure connectivity and how chain pickerel may be affecting food webs.
We are currently collaborating on several projects at those locations that focus on impacts of chain pickerel on vulnerable ecosystems and food webs.
