How to find a stocked lake
You can learn which fish species and locations were stocked with the Fish ON-Line tool, or if you are unable to access stocking information from the Fish ON-Line tool contact your nearest Ministry of Northern Development, Mines, Natural Resources and Forestry district office.
Fish stocking improves recreational fishing by:
- Providing chances to catch popular sport fish like Walleye, salmon and trout
- Allowing for longer seasons or higher catch limits in some areas
- Stocking fish in easy to access places
Fish stocking also protects and rebuilds fish populations, including species at risk. For example, the program is helping to:
- return Atlantic salmon to Lake Ontario
- find a way to culture at-risk mussel species
- culture a deep water cisco that disappeared from Lake Ontario in the 20th century
Fish raised in Ontario fish culture stations are released into:
- 1,200 water bodies annually
- 2,000 lakes and rivers on a 4-year cycle
Ontario is divided into 20 Fisheries Management Zones. Each zone develops a fisheries management plan that decides which species and water bodies to stock.
- Atlantic salmon
- Aurora trout
- brook trout
- brown trout
- Chinook salmon
- lake trout
- rainbow trout
- lake whitefish
Fish culture stations
Fish for stocking are raised in Ontario’s 9 fish culture stations. You can book a guided tour at any fish culture station. Three locations also offer a visitor centre.
