Beneath the murky surface of Hamilton Harbour thousands of giant goldfish are teeming, tearing up vegetation and threatening native species.

But now, thanks to a first of its kind study, researchers have a new weapon in the battle to keep the harbour from becoming a giant goldfish bowl.
 

It's called acoustic telemetry. About a dozen of the fish were sedated and fitted with sound-emitting tags about the size of an AA battery, allowing scientists with Fisheries and Oceans Canada to track where they move.

"There's only one other study of goldfish in a fresh water system and that's in a river, so there are no other telemetry studies on goldfish in freshwater lakes," explained aquatic research biologist Christine Boston.
