New acoustic alarms aimed at reducing whale entanglements are being fitted to shark nets between Mackay in north Queensland and the Gold Coast of Australia this week.
These alarms will be used until the end of November to coincide with the southern whale migration.
Queensland Shark Control Program manager Tony Ham says the so-called pingers are designed to alert whales to the location of the nets. Apparently the pingers make the nets stand out from the background noise of the ocean. According to Ham the whales will hear them and then have an opportunity to assess the situation and avoid the nets.
