"One thing is certain, even the monk Gregor Mendel (often called the father of genetics after his early work on pea plant cross-breeding) would agree that the genes this fish carried were unique and rare by today's standards."

A canned fish or a fish in the freezer can't pass on copies of it's genes. Clem Tillion once told me, about fortyfive years ago, that  "When a road crosses a river the fish will decline".  This is when I would walk almost the whole length of the Petersville road to get to the Deshka from the new Parks Highway. We all know how THAT turned out. I now regret what I did as adventurous as it was for a young man.
