Has anyone tried river cobbler?

[schroeder]

I've seen this in asda a couple of times, but have no idea how to cook it. It looks like a white fish like haddock/pollock, but 'cause it's called RIVER cobbler it makes me think it may be a fresh water fishy after all. Advice please

I've used smoked cobbler in fish pie and kedgeree and 'twas nice. It doesn't flake as well as haddock once cooked and is a firmer fish, but other than that, you can't tell the difference in the dishes I've used it for.
