Hi, can anyone tell me what these fish are?

They aren't great photos, but it's the best I could do on my phone.

I caught them both yesterday at Fontburn Reservoir in Northumberland.
Both were returned and swam off, but I don't know what they were. I've
only caught Rainbow Trout there before. It's also the first time I was
fishing with sweetcorn.

Cheers
