Pre-heat oven to 275∞ F. Lightly mist with oil spray the bottom of a shallow 3-quart baking dish (such as a 9- by 13-inch Pyrex dish).
In the baking dish, toss together the first 5 ingredients (through dill). Season with black pepper.
Season salmon with Pritikin Fish Seasoning and place on top of fennel mixture.
Roast until salmon is just cooked through, about 30 to 40 minutes.
Transfer salmon to a platter, breaking it into large pieces as you go. Don’t worry about perfect portions. Just keep in mind that one serving, whether made up of 1 or 2 pieces, is about the size of the palm of your hand.
Spoon fennel/citrus mixture from baking dish over salmon pieces. Discard dill sprigs. If desired, season with more fish seasoning and black pepper. Top with a few fresh dill sprigs.
