I have talked with several state fisheries biologists about this very subject and they have told me that there are in fact still fish from those original stocks returning so I gotta agree with Mark on this one. One major reason for the lack of 70 pound fish in the straits in addition to "diminished" returns is that commercial and sport fishing has severely limited the amount of fish that can survive in the ocean the 5 to 7 years it takes those fish to reach that size. Good Luck-TBJ
