In general, the history of non-native species introductions is terrible in many areas and for many species. I just can't see a good justification for wanting to keep these fish around.


Actually your reading of the study did not include the trapping/netting, i.e., locations based upon walleye migrations (they do do that to spawn), the timing of the migration, i.e., position in the river in relationships to the timing and locations of downstream migrating salmonoids -- Totally in different areas at different times. Hence the "Enhancement of Salmonoids."

Now exactly where are your studies that back up you OPINIONS?? Thought so, in the cave where the sun don't shine.
