MAZINA’IGAN PAGE 8 FALL 2017 Ghost net packs available for anglers Through a cooperative effort by a collection Lake Superior stakeholders, kits are now available to mark lost fishing nets. GLIFWC wardens joined the Apostle Islands Sport Fishermen’s Association, Department of Natural Resources, Wisconsin Sea Grant and others to help design a kit that includes a floating marker and hook-and-line assembly to identify the location of ghost nets. The kits are available at many South Shore bait shops.

All through the summer, interns Jalyn LaBine, Patrick LaGrew, and Jacob Rodmaker have gained valuable experience by participating in a variety of fisher- ies field work including: trapping sea lamprey on the Bad River, deploying gill nets to catch siscowet lake trout, and beach seining to catch juvenile whitefish on Lake Superior. The Bad River Natural Resources Department (BRNRD) began an assess- ment for siscowet lake trout with their new research vessel “Minwaanimad” (good breeze). Siscowet lake trout were targeted off the western shores of the Keweenaw Peninsula near Eagle Harbor, Michigan. This continues an assessment initiated by GLIFWC in 1996 at the request of GLIFWC’s Lakes Committee.

During their spawning run, sea lampreys are extracted from traps on the Bad River each day and are counted, measured, and sexed. A subsample of the invasive lampreys is fin-clipped and released back into the river for the purpose of obtaining an estimate of the adult population in the river. (J.

The purpose of this survey is to attain an index of relative abundance of juvenile lake whitefish from various locations around Michigan’s Keweenaw Peninsula. (B.

The intent of the siscowet lake trout survey is to document relative abundance and diet of siscowet lake trout by setting gill nets at varying depths on the eastern side of the Keweenaw Peninsula and collect- ing data such as length, weight, sex, and stomach samples from captured fish. (B. Michaels photo) GLIFWC fisheries internships provide experience on the water and in the lab- oratory. After collecting a load of lake whitefish (adikamegwag) stomachs from cooperating commercial fishermen, Great Lakes Division interns work in the lab, documenting whitefish meals that include macroinvertebrates, small fish, and European fingernail clams.
