I just hope that some are getting adjusted/evolving an ability to withstand cooler conditions. How nice would it be to have full time Talapia in the north? IIRC some Eel grass was originally only native so of the Ohio river but thru the yrs (and I believe Bill Codys coaxing) it is now doing well up here.
This would be horrible! Might result in tilapia being banned in more states than they are already.
