Zooplankton species composition during hatching and development of Atlantic whitefish (Coregonus huntsmani) in the upper Petite Rivière watershed, Nova Scotia

This research project aims to build a greater understanding of the diet of endangered Atlantic whitefish. The only wild population in the world inhabits three lakes of the Petite Rivière watershed in Nova Scotia. The species has great historical significance being the most primitive of all whitefish species in Canada. Yet, there is little known about this unique fish, including their diet. Since 2018, the non-profit environmental organization, Coastal Action, has collected samples of tiny aquatic invertebrates, zooplankton, which are a main food source for juveniles. Previously, samples were collected monthly from Atlantic whitefish habitat from June through September, and specimens were identified to determine the diversity of zooplankton species. This project intends to build on these records by sampling weekly, starting in late winter rather than early summer, which will provide insight on the availability of different zooplankton species during a critical period of juvenile Atlantic whitefish development.
