| Comments | Method of capture through observation. Confirmed. Noticed them for the first time near the dam at Sandfield, no sample collected but he knows what they are from fishing Lk. Huron. To try to confirm this sighting I spoke with John Lehman (U.S. researcher) who Norm Yan said had written in a research proposal that Bc were in this lake and others on the Island, he said he heard it from another researcher whos name he would try to get to me. Reporter indicated that many anglers fish with downriggers Lk. Huron/Georgian Bay and then trailer inland on the island to fish so it is likely that Bc have been spread to these lakes. |
