That's what they did in Montreal @ Beaver pond on Mont Royal

No. They have shown to be hardy over Candian Winters in lakes that do not have winter kill.

Careful... Unless specified in the regs this maybe qualified as allowing fish to spoil. Also many fishermen, though well intentioned are not able to make a definative identification. I have seen walleye called musky, redhorse being called carp, Ling being called american eel, people not able to sort out bluegill from pumpkinseed, Mooneye idetified as shad. A call/e-mail to MNR would be the best way to get an answer here.

Last time I was there was years ago but you should talk to the locals when the caplin are running in the nights. They should be spawning in the evening on the shores around this time. I saw some locals bring out the big rods and cast over the caplin to catch the predators chasing them into the shallows.

Black Crappie are not considered invasive but they having been moving northaward in the province for years. They are becomming more and more common in the Ottawa area. Invasiveness is a tricky subject. As it was in the region it was has not been dicussed as invassive as it was part of our eco system; Likley there is no threat or concern to the local ecosystems as we had similar fish (Small/largemouth bass, Sunfish) with similar habits. Likley the balance of the poplation to some small degree will shift but it is unlikley that oen will win out over the other. They do have natural predators in the enviroment so they will be in check. That being said Pike are considred invasive in zone 15 as they are affecting the ecosystem as a top of the food chain predator; There "invasion" through algonquin park is being tracked very carefully. They are directly impacting the ecosystem of the lakes they are introduced to.
