It is fish stocking season! DNR trucks are heading to locations across the state
April 27, 2026
Fish stocking trucks are hitting the road! It’s a busy season: This time of year, Michigan Department of Natural Resources fish stocking trucks are releasing their prized cargo — trout, salmon, muskie and walleye — at hundreds of lakes and streams statewide.
The DNR accomplishes this work by rearing fish at its six fish production facilities located throughout the state, along with other cooperative rearing facilities, and by maintaining a fleet of 18 specialized fish stocking vehicles.
More than 20 million fish (weighing more than 350 tons) are stocked by the DNR annually. Species stocked include steelhead; Atlantic, Chinook and coho salmon; splake (a hybrid of brook and lake trout) and brown, brook, lake and rainbow trout; muskellunge and walleye. Beginning in mid-March and ending in early June, the DNR fish stocking trucks will travel well over 100,000 miles to stock more than a thousand locations.
Some of the many fish stocked will be salmon that have been implanted with a coded-wire tag or are otherwise marked or tagged. These tags provide useful information on the fishery to fisheries managers. To learn more or report a marked or tagged fish, visit Michigan.gov/TaggedFish.
Why does the DNR stock fish?
“In some cases, stocking would be unnecessary or even detrimental to a lake or stream or to fish populations,” Blaauw said. “If a fish population is producing well naturally and in alignment with angling demand and management goals for that species, we don’t stock on top of those wild populations.”
Naturally reproducing fish are adapted to their environment, which can allow them to thrive without supplemental stocking. However, there are instances where the combination of angling pressure and habitat limitations do not allow wild fish to maintain the desired population level on their own. When that occurs, hatchery fish are stocked to supplement natural reproduction.
Visit the DNR’s fish stocking dashboard for information on local fish stocking locations. The dashboard has recently been updated and has a new, more user-friendly interface.
