Results of Fisheries and Oceans Canada's 2014 Asian carp early detection field surveillance program: Fs97-4/3103E-PDF
In 2014, an early detection field surveillance program for Asian carps in the Great Lakes and its watersheds was continued for a second season by Fisheries and Oceans Canada’s Asian Carp Program. The field program built upon the early detection sites selected in 2013, and continued to identify sites to monitor that were high risk for Grass Carp (Ctenopharyngodon idella), Silver Carp (Hypophthalmichthys molitrix), Bighead Carp (H. nobilis) and Black Carp (Mylopharyngodon piceus) arrival and establishment in the Great Lakes. In the spring, summer, and fall of 2014, 745 sites were sampled at 36 locations on the Canadian side of the Great Lakes (lakes Superior, Huron, Erie, and Ontario). Several gear types were used to capture fishes, including: boat electrofishing units, fyke nets, hoop nets, seine nets, tied-down gill nets, trammel nets, trap nets, and trawls. A total number of 43,928 fishes representing 92 species were captured. Surrogate species for Asian carps (Buffalo spp., and Common Carp) were detected in all gears except for seines and trawls. A total of 346 Buffalo species (Ictiobus spp.) were captured, and 1774 Common Carp (Cyprinus carpio). One triploid Grass Carp was captured in the Grand River on September 23rd, in a trammel net. Although new early detection locations were scouted and sampled, not all will be carried forward as long-term monitoring sites. Additional sites will be scouted in the Huron-Erie corridor, and in eastern Lake Ontario in 2015.
