For a treat or supplemental feeding, the salmon (however it's prepared) should be fine, I just wouldn't feed it too frequently. There's an interesting article here on the fish and cats.

Supplementation could provide for correct amounts of Calcium within the right ratio with Phosphorus, and could bring levels of vitamins - such as vitamin A, D, E, and complex B, to optimal levels. However, fish meat seems to contain insufficient amounts of the trace minerals iron, zinc, copper, and manganese, making fish meat in the end an unsuitable choice as a base for a staple feline diet, because it would require unreasonable supplementation. .....

Fish, no matter if whole, dressed, raw, cooked, or canned will cause nutritional deficiency of some kind, which in turn will eventually lead to serious disease. If fish is to be included in the meal plan of the domestic cat, one may only do so sparingly as treats, or to entice a sick cat to eat. Other than that, the story of fish and cats shall remain a fairytale.
