I say we introduce some BD rays to take care of them... lol... then harvest for us!!!
Very surprising.. The guy must of done alot of resaearch i bet that isnt the only South American/ Sentral American cichlid down there in those waters.
I'm shocked that dempseys can compete for food with a largemouth. Actually, I'm shocked that a Dempsey ISN'T food for a largemouth.

I had a thread going previously about cold hardy cichlids, and what it would take to breed cichlids that would survive colder and colder waters. Seems someone took that to heart, as eventually, the dempseys will survive further and further downstream.

Yup they would reduce the population and are native fish.

Its not unheard of, we have had a population of sailfin mollies thriving in a geothermally heated stream in the central North Island (where it can get below freezing during winter) for decades now. I don't think the authorities are concerned about them as there aren't any natives in the warm water, which makes me tempted to go let a bunch of festae or jags or something cool loose to see what happens. I know it wouldn't be good in the long run though, its hard enough to import fish here as it is, something like that might just give them the motivation they need to restrict imports even more...
