Re: Re: NFC: DP returning fish to the wild
I agree with Robert and recall there was a well known historical
incident with bobwhite quail that is commonly used in wildlife biology
classes to illustrate what can happen when you intermingle regional
populations. Seems that early in this century, the northern quail
hunters decided that they had too few quail in their area, having shot
them all off, so they imported a whole bunch of quail from the
Southeast, where they were still plentiful. Birds were released and
interbred with the resident quail. Winter came and the entire
population was exterminated except for some isolated pockets of quail
that hadn't been mingled with their southern kin. Seems that the F1's
did not have the appropriate genetics to deal with northern winters.
This is both reassuring and frightening at the same time. Southern
species will generally not survive northern winters. The frightening
part of it is that they may take a lot of other individuals with them
when they go.
'Nuff said.
