Green Bay Fish and Wildlife Conservation Office

The Green Bay Fish and Wildlife Conservation Office implements the Service’s Fisheries Programs in the Lake Michigan and Great Lakes basins to conserve, protect, manage, and restore native fish and the habitats they rely on. We partner with many state, local, non-governmental, tribal, and other federal agencies and organizations and encourage cooperative management of fishery resources of the Grea

t Lakes. Our Programs include:

-Native Species Conservation: Focuses on restoration, rehabilitation and conservation of important native fish populations, with emphasis on lake trout, lake sturgeon and lake whitefish.

-Mass Marking of Great Lakes Stocked Trout and Salmon: Provides coded-wire tagging, tag recovery, and other science support services to state and tribal agencies that stock trout and salmon into the Great Lakes.

-Habitat Restoration: Coordinates with partners to restore quality fish habitat including instream, riparian, wetland, coastal, lake and upland habitats benefiting native species in the Lake Michigan basin.

-Aquatic Invasive Species: Conducts activities for the prevention, early detection, and rapid response planning of aquatic invasive species introductions. The work we do helps to maintain the overall function and health of the Great Lakes, providing opportunities for Americans to enjoy the outdoors and our shared natural heritage. We are devoted to the management of these important natural resources to preserve them for present and future generations.

Day-to-day tasks in a fisheries field sometimes mean dealing with motor maintenance. Knowing how to handle basic motor maintenance, such as unclogging water lines, changing oil and spark plugs, and replacing propellers, allows our crews to work efficiently when operating in remote areas.

Our gillnets are marked with stick-buoys, which are 10-foot-long metal tubes held afloat with a bright orange bullet float and counter balanced to be vertical with a weight and chain. The elevated part of the stick is adorned with a bright orange square flag with a reflective silver X across it on both sides. These stick buoys mark either side of our gillnets (attached via rope and anchored to the bottom), and we place our nets anywhere deeper than 3 meters of water and not within a major shipping channel. If you see one buoy, be sure to look for the other!

Freighters on Lake Michigan carry large loads of raw materials from one port to another. Please watch out for everyone using the water, from swimmers to freighters, and remember to yield the right-of-way to the less-maneuverable vessel.

Low water cause many docks and boat launches to not be as effective as they are in normal-water conditions. Always inspect a boat launch prior to use, and use three points of contact when transferring yourself from between a dock and a vessel.

A dock sits mostly on dry land on a sandy boat launch. The river is calm and highly reflective of the trees on the opposite bank.

Always some mixed feelings when an invasive species is encountered. For our grass carp crew the capture of this fish (on the countertop) is the result of many hours of field effort. Each grass carp removed from the Lake Michigan basin is a benefit to the natural ecosystem!
