Results of Fisheries and Oceans Canada's 2017 Asian Carp early detection field surveillance program / by J. Colm, D. Marson and B. Cudmore. : Fs97-4/3168E-PDF

"In 2017, Fisheries and Oceans Canada’s Asian Carp Program continued early detection field surveillance for Asian carps in Canadian waters of the Great Lakes. Four crews sampled 1 051 sites from spring to fall at 30 locations in tributaries and connecting channels within the basin. Seven gear types were used to target large-bodied and small-bodied fishes in habitats well-suited to different life stages of Asian carps. A total of 50 893 fishes were captured, representing 87 species. Surrogate species that share similar habitats and feeding preferences to Asian carps were used to assess the effectiveness of the gear types and sampling techniques. Captured surrogates included 887 buffalo (Ictiobus spp.) and 1 955 Common Carp (Cyprinus carpio). No Asian carps were detected during the early detection surveillance work in 2017. The Toronto Region and Conservation Authority sampled a further 160 sites in five waterbodies targeting Asian carps. Additionally, DFO sampled 43 sites with two gear types to search for eggs and larval Asian carps. In 2018, the Asian Carp Program will continue to sample areas that are high risk for the arrival of Asian carps in Canadian waters of the Great Lakes"--Abstract, page v.
