Found an interesting article....

Some interesting stuff......use of the word "Whole" identifies the whole fish was used, not just the skin, scales, bones, blood, and other leftovers deemed unsuitable for human consumption, as may be the case with a generic "fish meal", although some fish meals are comprised of whole fish.
