(DNR) – The Wisconsin Department of Natural Resources (DNR) today released the 2024 fish stocking numbers for inland waterbodies and the Great Lakes.
The DNR raises millions of yearling and fingerling fish to stock into Wisconsin waters every year. Over 5 million fish were stocked in 2024, which helped fulfill the quotas submitted by county fisheries biologists.
Stocking helps boost natural fish populations where natural reproduction can no longer support the fishery, maintain or restore existing fisheries and support recreational fishing opportunities. Stocking is also used to evaluate management actions or fish culture techniques.
DNR biologists analyze data collected from present and past surveys to determine which species and quantity should be stocked, along with other factors such as:
- Public input received during the development of species-specific management plans
- Experimental fisheries management strategies
- Specific watershed goals to restore self-sustaining fish populations, maintain existing fisheries or create recreational ones
DNR fish crews stocked fish in inland waters, Lake Michigan, Lake Superior and their tributaries across the state in 2024.
