The 8th Biennial Report of the Michigan Department of Conservation as the following description of the meeting on Page 136 and the photo was on Page 120:
Michigan was privileged to entertain the 13th Annual Convention of the International Association of Game, Fish and Conservation Commissioners and the 66th Annual Meeting of the American Fisheries Society at Grand Rapids, August 31 to September 4, 1936.
One of the highlights of the convention was a joint field trip on September 2, which included visits to the W.K. Kellogg Bird Sanctuary near Gull Lake, and to the Wolf Lake State Fish Hatchery near Kalamazoo where a complimentary luncheon was served by the Department of Conservation. About 350 delegates weer in attendance representing 31 states, Canada, England, Mexico, Brazil, Cuba, and Japan. Thirty years ago, the meeting of the American Fisheries Society was held in Michigan, also at Grand Rapids.
