>> There are only two valid reasons that come to mind for not releasing hybrid specimens, or translocating specimens, from one population to a distant region where the same species occurs (in your case the Ringneck Snake). One reasons concerns the introduction of 'non-native' mtDNA. . . .The second reason is that when specimens are released into unfamiliar

>>areas that are likely to be at or near saturation levels of the same species, they are placed at a huge disadvantage and such introduced specimens are not likely to survive. . . .



>> For years, many wildlife agencies have been bastardizing fish populutions including many trout populations here in the west.



Would a valid third reason be the possible introduction of parasites/disease into an otherwise healthy population? Your example of trout made me think of whirling disease.
