Put fennel seeds in coffee grinder and pulse to chop roughly. Mix with rest of dry ingredients.
Rinse and dry the salmon filet, drizzle and rub olive oil on top and bottom. Add salt and pepper to taste, grind lemon peel over salmon filet and sprinkle the marinade to cover the fish. Let rest for at least 30 minutes before cooking. You may pan-fry, just be careful to not burn marinade on the fish.
