I was reading an old post about the way lake Charles was being managed/mis managed
as far as crappie size. The statement was made that saugeye were a good fix for stunted crappie:

we cannot stock them in Lake Charles because the saugeye could escape and start breeding with the sauger in the Black River. We will continue to gather info on this population this coming fall. We are going to be looking at specifically at diets this fall.

However :Saugeye are considered "sterile" but have been scientifically documented to have some reproductive capabilities with both saugeye, walleye, and sauger, though all in low percentages.

And: There are both walleye and sauger already in Black river...Isnt the liklihood of saugeye reproducing naturally a more likely senario for the Blackriver sauger gene pool to be corrupted by saugeye...

Therefore: There is no REAL reason not to put saugeye in lake Charles...

Seems like Game and Fish uses some pretty convoluted logic to me...
