Includes bibliographical references (pages 33-54). "Aquatic invasive species (AIS) are species introduced or spread to ecosystems beyond their natural range that threaten biodiversity, economy, and society. Recently, four freshwater fishes were identified as being of concern for Canadian freshwaters: Goldfish (Carassius auratus), Prussian Carp (Carassius gibelio), Black Crappie (Pomoxis nigromaculatus) and Chain Pickerel (Esox niger). The latter two species are native in some regions of Canada, while the carps are strictly non-Indigenous. All four species currently have at least one non-indigenous population established in Canada and are undergoing range expansions. A screening-level risk assessment (SRLA) was performed using an adaptation of the Canadian Marine Invasive Screening Tool (CMIST) to identify the level of risk (high, moderate, or low) of these four species across freshwater ecoregions in Canada"--Abstract, page ix.
