The Canadian Aquatic Invasive Species Network (CAISN) was established with the goal of identifying and quantifying the vectors and pathways by which aquatic invasive species(AIS) enter Canada, determining factors that affect their colonization success, and developing risk assessment models for potential and existing AIS. This program ran between 2006-2011. The CAISN II project (2011-2016) was designed to provide a comprehensive profile of AIS in waters across Canada and develop and determine effectiveness of tools for early detection of, and rapid response to invaders. This resource contains the information on a CAISN II baseline study for benthic invertebrates in search of non-indigenous species (NIS) from the Canadian Arctic coasts made during summers 2011-2012. more

This survey identified as well native species by incorporating historical information to identify new records. The top three ports at highest risk for introduction of NIS of the Canadian Arctic were surveyed: Churchill (Manitoba), Deception Bay (Quebec) and Iqaluit (Nunavut). It also includes information on Steesnby Inlet (Nunavut) that was sampled given that it is a proposed site for the construction of a new port. A total of 287 genera and species were identified. Increased survey effort is the most likely explanation for the majority of new occurrences, however, a small number of records (n=7) were new mentions for Canada and were categorized as cryptogenic since we could not confidently describe them as being either native or introduced. Further research is required to better understand the status of these new taxa. This dataset formed the basis of a PhD thesis (Goldsmit, Jesica 2016).
