Acoustic tagging device tracking fish in Lake Ontario

TORONTO – A team of Toronto scientists is using a new, high-tech way of tracking fish throughout Lake Ontario.

An acoustic tagging device is being planted into fish in the Lake Ontario in order to track their movements.

“We’re getting a good indication as to migratory movements: where fish are located, where they’re spawning,” said Adam Weir, a representative of the Toronto and Region Conservation Authority.

Over 50 signals placed around the Toronto harbour monitor the sound from the tagging devices to track the fish.

It also allows them to track non-native species of fish, which can displace local species.

A tricky part of the process, however, is catching the fish.

The Toronto and Region Conservation Authority used an extremely small amount of electricity that temporarily stuns the fish.

When the fish are stunned, the scientists input the tracking device.
