The creation of surfboards with shark deterring fins, beach noise mufflers and acoustic shark detectors are to be funded by the West Australian government.

These three projects, including research into what triggers shark attacks, have been awarded almost a million dollars in backing in the second round of research funding as part of the state government's Shark Hazard Mitigation Strategy.

The WA government began funding such research in 2012 following a spate of shark attacks.

In the past three years there have been seven fatal shark attacks in the state.
