Is pollock and whiting the same fish?
No, but they are related. Pollock is much Whiter in color and more mild tasting. Whiting is sold skin on and skin off, whereas Pollock is almost exclusively sold skinless.
Both are found in both the Atlantic and Pacific Ocean. For the most part, the Atlantic versions are superior. Both fish are used in Imitation Crab Meat as well as Fish Stick because they are inexpensive to use and readily available.
Pollock is very mild and usually cheaper, but whiting is fishier, but many people will say it has more flavor.
Both are suitable to bake or fry, and are cheaper cousins to Cod and Haddock.
