I'm simply stating that thosewords dont cite any specifics. Only a general objective.Without specifics, we have no idea what was meant in the 60's vs now when that statement was made. For instance, maximum breeding stock is not defined. I'd guess it was with a MSY goal back then but who really knows without more information?

Part 2 is that it only makes sense that the underlying scientific data of today is more refined and reliable than it was 60+ years ago
