Is 6oz of raw frozen salmon the same weight as cooked salmon?

No, 6 ounces of raw frozen salmon is not the same weight as cooked salmon. When salmon is cooked, it loses moisture, fat, and some weight due to evaporation and cooking processes. Typically, cooked salmon weighs about 20-25% less than its raw counterpart, so 6 ounces of raw salmon will yield approximately 4.5 to 5 ounces when fully cooked.
