I recently had the opportunity to join Fisheries and Oceans Canada staff for a day of invasive fish species surveillance on the St. Lawrence River. The targeted invasive species for this surveillance initiative were Grass Carp and Tench. This was a fascinating experience from start to finish! I have partnered with Asian Carp Canada and the Invasive Species Centre on a variety of awareness campaigns over the past few years, and am grateful to work with them once again for this blog post. Having the chance to get out in the field and seeing this important work conducted first hand was a definite highlight for me!
My Day on the Water with DFO
My day began meeting up Fisheries and Oceans Canada (DFO) staff, Greg, Trisiah, and Taryn at a boat launch in Cardinal, Ontario. After introductions and chatting about plans for the day, they launched the research vessel and we were on our way to the first site they had selected for surveillance.
Setting Mini Fyke Nets
Upon arrival at the first site, the technicians recorded environmental data using various instruments. Some of the data they collected included: water and air temperatures, water quality parameters, river substrate, and aquatic and riparian vegetation.
Greg then donned a pair of waders and got into the water to set mini fyke nets, which they would return to collect the next day. Fyke nets are a type of fish trap typically set from shore in shallow waters. Their funnel-shaped design, supported by hoops or frames, guides fish into an enclosed section from which it is difficult to escape. Fyke nets allow fish to be captured while remaining in the water, minimizing harm.
