Looking beyond the macronutrients, Salmon is the better source of selenium, vitamin B12 (see the vitamins and minerals table below).
Salmon has more protein, selenium and B12, and its fat is rich in omega-3 EPA and DHA; farmed catfish fat is mostly omega-6 and monounsaturated. Calories are nearly identical.
In short: for protein and muscle, Salmon. If none of those goals applies, pick by taste, price and what the recipe needs.
