Did some quick research and looks like Ontario is stocking three strains of lake trout in Lake Ontario (Slate Island, Seneca Lake, Michipicoten Island strains). Cobourg had all three stocked last year, other major stocking locations are Brighton, Scotch Bonnet and Amherst Island to Main Duck. Looks like Mishibishu stain were last stocked in 2006 and were the river run strain from what I can tell. NY also stocks Seneca Lake, Lake Champlain and Lake Superior strains.
Here's some info from the Lake Huron restoration report:
http://www.glfc.org/pubs/SpecialPubs/Lk ... pHuron.pdfSlate Island Strain - Shallow Water (Lake Superior Origin), Michipicoten Island Strain - (Lake Superior Origin)“The Slate Island and Michipicoten Island strains of lake trout originated from wild Lake
Superior stocks. These two strains are currently being used in rehabilitation efforts in
Canadian waters of Lake Huron. Growth and maturation rates of the Slate and
Michipicoten Island strains appear to be slower than for the Lake Manitou strain. These
two strains seem better suited to areas of Lake Huron where sea lamprey and fishing
mortality are low due to characteristic slow growth. Stocking additional Lake Superior
strains will increase the genetic diversity of Lake Huron lake trout stocks, as suggested
by various authors at RESTORE.”
Seneca Strain - Deep Water (Seneca Lake NY Origin)“The Seneca strain of lake trout, especially at small sizes, appears to be more resistant to
both sea lamprey predation and commercial and sport fisheries than other strains stocked
in Lake Huron. No Seneca-strain lake trout < 532 mm in length captured during 1991-95
in Lake Huron bore sea lamprey marks. By way of comparison, sea lamprey marking
rates on other strains at comparable sizes had sea lamprey marking rates that were up to
ten times greater. In northern Lake Huron, Seneca-strain lake trout are subjected
to intense sea lamprey predation rates, yet this strain still grows to reproductive size.
Age-10 Seneca-strain lake trout were captured on spawning grounds in the Drummond
Island Refuge in 1995. Most other strains of lake trout that live in MH-1 do not survive
past age 6.”
