I think it may be a salmon but the green colour is throwing me off.
Do you have any more information? Where did you catch it?– Chris MendezNov 17, 2015 at 2:03
@ChrisMendez in a river in Southern Ontario a few km from lake Ontario– user1084113Nov 17, 2015 at 3:00
Looks kind of like a walleye to me.
I didn't think there was anything else worth catching in Ontario, in NW Ontario at least this is what everyone goes fishing for, they're one of the tastier fishes.
They're fighters too, you always expect them to big bigger than they are when you reel them in.
