Pink fish isn't going to be super high in fat. The bet way to figure out how much fat he is actually getting is to have a nutritionist analyze the recipe. Unfortunately, because there are no supplements added and a substantial amount of homecooked is being given, it will likely come back showing nutrient deficiencies.
My pancreatitis-prone girl eats tuna. She used to eat whitefish. White meat chicken and turkey would also be ok for most pups. Anyway, would not feed any fish that is said to be fatty without nutritionist oversight. I hope that wasn't too confusing.
