Here is some information:
http://www.nativefish.asn.au/barramundi.html I can't believe the sizes:
Up to 1.8 m and 60 Kg (6' & 130 lb), common to 1.2 m
I have a question, now that the barramundi have wiped out several generations of other species, when will the other species fry start to survive and create the food chain?
You may have created a monster with their teeth, size, and voracious appetite. Is there anyone else that stocks these fish in ponds in your area? Maybe you could find someone with experience. Without any other information I would cull the barramundi until you reach some kind of balance in your pond.
