Some fishermen tell me I caught a Trout Salmon. Does this fish differ much from ordinary salmon? Like the title says, got a couple questions about the fish I just caught...

Firstly, is there anyway to confirm what type of fish this is? 'Ordinary salmon' or 'trout salmon'?

Lastly, does it differ much in taste from 'ordinary' salmon? I want to search for some good Salmon recipes but I want to be sure I'm looking at the right recipes for the right fish.

Cheers.
I've had Salmon Trout.  They are a pink fleshed trout, that mimics the flavour of Salmon somewhat.

My favourite preparation is to do it as a Yerevan Trout.  Essentially Roast the fish filets, prepare the sauce - Lemon, Butter, Capers, Artichokes, and any pan juice you can get.  Serve beside your favourite rice.
