I'm no gar expert, but wouldn't you need an exit plan to get the gar back out once they have thinned the herd? I bet gar are kinda like flathead cats in a small BOW...big and hungry.
I was hoping they would become too stunted for the largest game fish and just continue to eat the medium-large game fish over the generations, self-sustainingly.
I can't answer the question, mostly because I've never seen it asked before.
Uh-oh. Did I just invent the stupid question?
This is largely because gar become a problem in nearly every body of water they get into.
That's depressing.
They overpopulate, eat everything in sight, and don't get very big. Be very careful. You could end up with just a bunch of hungry pencils swimming around.
Do they really eat
everything? I hate giving up my dreams of a pond full of "living fossils". Are there any case studies of successes/failures with these guys in private BOWs? What keeps their numbers in check out in the wild?
