Panfishers regularly catch Oscars in some parts of the Everglades. Is this canal isolated? If there was no chance for spreading, having an isolated waterway full of year-round resident exotics might be kinda cool to fish in haha. I dont think 100% guaranteeing that there wont be spread is possible though. There are places in Thailand(???) where you can go fishing in reservoirs and catch Pima, Redtails, Pacu, and Gar, I believe.
