Hi Curt,

Good to hear from you and always nice to see a few pics. To be honest I have not had time to do any open water brook trout fishing this year … bummer. Too many things to do and not enough time. Your kayak videos give me something to look forward to in retirement – only 2 years left. I do most of my brook trout fishing these days on the ice.

As far as brook trout strains go, there are numerous wild strains obviously as any natural brook trout population may show subtle genetic differences.

I believe there are 4 strains currently in the provincial hatchery system: the Hills Lake domestic strain (a very old domesticated strain), the Lake Nipigon wild strain, a hybrid of the two (Lake Nipigon X Hills Lake), and most recently a Dixon Lake wild strain from Algonquin Park believed to be more tolerant of warmer water. The Dixon Lake strain is not widely available for stocking.

In Sudbury we stock mainly the Lake Nipigon X Hills Lake hybrid. They tend to grow faster and produce a better put-grow-take fishery. And, yes I have seen them exceed one pound in their first year (2 years of age as they are stocked at one year old), achieve 3 pounds in 2 years, 5 in 3 years. They rarely live beyond age 5 or 4 years after stocking. If we are trying to establish a self-sustaining population we occasionally use the Lake Nipigon wild strain although the hybrid strain will also establish if conditions are suitable.

Any other question feel free to ask.

Regards,

Wayne

I am told 2 out of 10 lakes in the sudbury area will reproduce with the stocked fish.

I know of 4 lakes that have produced 5 lb fish.

Great info Curt. The Dixon strain is interesting as I believe warming brook tout waters is a problem years down the road. We’ve already lost a number of brook trout lakes due to warmer temps that are now stocked with splake in the Minden area.

I'd invite that biologist and his wife over for dinner and drinks, then mix his drinks really strong and start digging for more information, lol.

Very interesting stuff.

I remember being a student working for the Minden MNR. It was a rain day and we were stuck in the office. With nothing to do, I was riffling through filing cabinets, reading stuff, lol. Being a kid who liked to fish, the information they had blew my mind.

It isn't so much an issue of how clean the water is. Brookies need abundant springwater inflow in order to have reproductive success. Stocked fish can survive just fine without it, so long as they have cold water refuge in the summer, but without it they won't spawn successfully.

Thanks Troutbandit great info makes sense why most of these Brooke Trout lakes have many over hanging trees which keeps the lakes cooler.Happy Thanksgiving. 🦃

I once read in an algon park pub that they need gravel to spawn on which, from my experience, is patently untrue.

🤔....I've travelled a lot of Algonquin Park, and have never come across this pub you speak of. Frigg that would be a fine sight at the end of a 3km portage!!🍺

It was called "Fishing in Algon" or some such. Quite a forgettable pub!
