Sydneys Artifical Reefs

Bruce Hatcher

When Sydney Harbour was dredged last year, some fishing ground was destroyed.

Compensation for that comes in the form of replacement habitat.

Over the last few months, 750-thousand tonnes of rock was deposited in the harbour, and now there are 8 new artificial reefs in strategic underwater locations.

Bruce Hatcher is Chair in Marine Ecosystem Research at Cape Breton University. He spoke earlier today with reporter Yvonne LeBlanc-Smith.
