We’re in the midst of our spring fish-stocking season, so you may be seeing DNR trucks releasing their prized cargo at hundreds of lakes and streams throughout the state.

Fish stocking is a valuable tool used by fisheries managers to restore, enhance and create new fishing opportunities in Michigan’s inland lakes, streams and the Great Lakes. he DNR accomplishes this by rearing fish at its six fish production facilities located throughout the state, cooperatively managing nearly 40 rearing ponds and six Great Lakes imprinting net pen locations, and maintaining a fleet of 18 specialized fish-stocking vehicles.

Over the course of a typical year, upwards of 20 million fish (weighing nearly 350 tons, including eight species of trout and salmon and three cool-water strains of walleye and muskellunge) are stocked. Beginning in mid-March and ending in early June, the DNR fish-stocking trucks will travel well over 100,000 miles to visit between 700 and 1,100 locations. Read more

The Upper Peninsula’s northern pike and walleye season opener is coming soon! On Tuesday, May 15, the season opens on all U.P. waters, including the Great Lakes, inland waters and the St. Marys River.

Please note, the season opener for muskellunge in the U.P. has changed – in addition to all other waters in Michigan. On all Great Lakes and inland waters, the St. Marys River, the St. Clair River, the Detroit River and Lake St. Clair, the season doesn’t open until Saturday, June 2. But catch-and-immediate-release muskellunge fishing now is allowed on all waters all year.

Anglers can currently catch and immediately release largemouth and smallmouth bass on most waters statewide. The possession season for bass opens statewide on Saturday, May 26, except for Lake St. Clair, the St. Clair River and the Detroit River, which open on Saturday, June 16. Read more

New video gives tips on identification, response

Parrot feather (Myriophyllum aquaticum), an invasive aquatic plant, has been found in three private ponds in Michigan since 2013. Due to its aggressive growth, parrot feather – a popular aquarium plant sometimes sold under the name Brazilian watermilfoil – has been a prohibited species in Michigan since 2005.

Why be concerned?

Parrot feather prefers slow-moving, freshwater habitats including ponds, lakes and tributaries. Plants rooted in lake or stream beds can grow to 6 feet in length, extending above or across the water’s surface as dense mats of vegetation that block native plants, reduce fish habitat, and make fishing and boating difficult.

Because new plants readily sprout from stem fragments, removal efforts like raking or pulling may contribute to their spread. Failure to thoroughly remove plant debris from boats and trailers can allow parrot feather to hitchhike to new locations. Read more

Arctic grayling reintroduction supported by grant from Petoskey-Harbor Springs Area Community Foundation

Michigan’s historic effort to reintroduce Arctic grayling to the state’s waters will be supported by a grant of $11,000 from the Petoskey-Harbor Springs Area Community Foundation to the Michigan DNR’s Fisheries Division.

Arctic grayling thrived in northern Michigan’s cold-water streams until the onset of the 20th century. Fishermen and wildlife enthusiasts visited destinations such as the Au Sable River to see this beautiful fish. But by the 1930s, three factors contributed to their demise: habitat destruction from logging, overfishing and competition with introduced trout species. The local extinction of this wild, native fish was a tragic loss for Michigan. Read more

As this year’s open-water fishing season gets under way, anglers trying their luck on Michigan lakes, rivers and Great Lakes ports can expect to see Department of Natural Resources fisheries staff out and about collecting key data about those experiences.

DNR creel clerks are stationed at boat launches and piers around the state, asking anglers questions as they return from fishing trips. The clerks will ask about things like trip length, target species and the number and type of fish caught. In some cases, clerks may ask to measure or weigh fish and to take scales or other body parts for aging – these details provide key information that helps the DNR take care of the state’s fisheries.

“We really appreciate angler cooperation with these interviews, and it only takes a couple of minutes to answer the questions,” said DNR fisheries biologist Tracy Claramunt. “This program helps us gather information that is critical in managing fish populations and health. It’s information that truly is used in every aspect of our management efforts.” Read more
