Fish Stocking and Genetics Management
Stocking and Genetics in Wisconsin
Wisconsin has a long and storied history of fish stocking. Advances in genetic analysis and lower-cost genetic testing have enabled more detailed stock determination, allowing fisheries biologists to better allocate stocked fish based on genetics and maximize natural reproduction, survival, and growth. Preserving the genetic integrity of fish stocks that are documented and proven to survive and thrive in Wisconsin waters is a central goal of fisheries management in Wisconsin.
Genetics Management Meeting
Are you interested in fish stocking or have questions related to the importance of fisheries genetics in stocking? If so, please consider attending a public meeting about the DNR’s fisheries genetics management plan. The purpose of the meeting is to present our fisheries genetics management plan and receive public input related to this plan.
Fisheries Management Meeting On Statewide Genetic Management Plan
Where: DeBot Dining Center
UW-Stevens Point Campus
325 Isadore St, Stevens Point, WI 54481
Room 053-055 Lower DeBot
When: Jan. 28, 6-8 p.m.
Although this meeting has been scheduled as an in-person event, a virtual option will also be available.
Share your input from the meeting at DNRFWPFHStockingGenetics@wisconsin.gov.
Genetic Management Guidance
Stocking should be used on a case-by-case basis. Waters with adequate natural reproduction, which provide some of the best fishing opportunities in the state, should not be stocked.
Genetic Management Units
Genetic management units (GMUs) have been identified for Wisconsin fish species. Fish within these GMUs are genetically similar, whereas there are genetic differences between GMUs.
Strains
Appropriate strains typically display high survival and growth to maximize return on stocking investment while also preserving the genetic integrity of wild populations.
Process to Acquire Strains
Bid requests for the sale of surplus walleye and muskellunge fry will be available on the DOA eSupplier website in February.
Requirements:
- Bids must be at least 8 ounces
- Bidders must have a Type 3 Fish Farm License
- Fish must be stocked in Wisconsin waters
Note: It has been shown that post-stocking survival is best if gametes are collected each year.
