So it becomes a case of whether you are a "lumper" or a "splitter". Furthermore, the Welland Canal and the Erie Canal/Genessee River route eliminated the up-stream blockade for about a century prior to the Lake Erie population extinction. Also, this argument has not prevented the re- introduction of various trout into waters where they had been lost (or wolves or grizzleys). Or the re-introduction of large-mouth bass into several isolated lakes in Western NY which froze solid and killed off everything after the blizzard of 1977. If they are to use this argument with Blue pike, then they should do so with other fish as well. B) The argument I got from them was not along your line of population isolation/genetic divergence. It was simply that "The Blue Pike is extinct, that's all there is to it, we can't go wasting tax-payers' money chasing every rumor and fisherman's tale we hear. They aren't Blues. They might be yellows with a little of the genetic make-up of the blues giving them a blue-ish cast, but they aren't Blues. Period. Now go away and quit pestering us." Bob
