What type of fish is this?

[Username]

I was recently fishing in SE Ontario and caught a couple of these fish.
I need some help identifying them. Are they Grass Carp (Invasive) or Common Carp?

Thanks for all the help!
Ill be fishing there again this weekend and want to know if i should be putting them back or disposing of them

I'm pretty sure that's a non-invasive sucker.

You should take a look a thttp://files.ontario.ca/environment-and-energy/fishing/198234.pdf so you are aware of what fish are around and always check the regs.

my guess is white sucker. they turn darker when they are spawning

Actually, they are a very important part of the food chain. Rainbow trout rely very much on these. When you start getting drop backs, watch where the bows are positioned while the suckers are spawning.

Bugle Trout, definitely.
