Buoys to help track and rescue whales tangled in fishing gear will be deployed along the West Australian coast.

The 10 trackable devices will allow WA Parks and Wildlife to remotely monitor entangled whales from Esperance to Broome.

About 35,000 whales will migrate this winter.

The technology was developed by scientists from the Department of Biodiversity, Conservation and Attractions, with joint funding from the state and federal governments.

WA Environment Minister Stephen Dawson said the devices will give rescuers more time to disentangle the gentle giants.
