Tom Reimchen's stickleback work on Haida Gwaii has been gradually transitioning to my lab at McGill University. I visited Drizzle Lake with Tom (on his permits) three years before bringing my own student last year. (Sarah Sanderson – whose name was on the permits from last year.) In the upcoming summer, we will sample a previously understudied component of stickleback biodiversity on Haida Gwaii - stream populations. Some stream populations have previously been sampled and studied by Tom and collaborators. However, nearly all of the previous work has focused on lake populations. My own previous experience has been with lake-stream population pairs on Vancouver Island. My goal this year is to conduct similar work on Haida Gwaii - thus seeking to add to our knowledge of this part of the biodiversity of Haida Gwaii stickleback. Dizzle Lake and its inlet and outlet stream have previously been sampled by Tom Reimchen - and so it is critical to include them in the present broader survey. Without these new samples, we won't have a reasonable way of comparing the new samples to the previous samples. At each site (lake, inlet, outlet), we will use standard minnow traps (empty or baited with cheese) to sample a maximum of 50 fish. The traps will be left to "soak" for hours to days (checked at least every 12 hours) depending on capture rates. All non-target fish will be recorded and released. Fish will be euthanized with an overdose of clove oil or MS222, preserved in ethanol, and transported to the Redpath Museum at McGill University (where Tom Reimchen's collections now reside) NOTE: I am Professor at McGill University, and I have studied threespine stickleback in BC for more than 25 years. Further, I have participated extensively in various assessments and research on SARA-considered populations, including Misty Lake and Haida Gwaii "Giant" populations.
