Monkey Mia

Monkey Mia dolphin history

In the 1960s fishers returning to Monkey Mia began sharing their catch with some of the dolphins. Over the years trust grew with more dolphins being fed at the jetty and later the beach.

Early dolphin feeding

Researchers arrived and have been continuously studying the dolphins since 1984. Among the researchers’ findings was that the mortality rate among the calves of beach visiting dolphins was significantly higher than that of other dolphins in Shark Bay. This led to the development of guidelines to ensure the young of beach visiting dolphins were raised with as much chance of survival as other wild dolphins.

The Department of Parks and Wildlife manages the Monkey Mia dolphin experience according to these guidelines by regulating dolphin feeding, maintaining the dolphin experience area, careful recruitment of new dolphins, and regulating boat encounters.

Regulating dolphin feeding

Between 1987 and 1994, 92% (11 of 12) nursing calves born to hand-fed females died. The high mortality rate was attributed to a combination of overfeeding, indiscriminate feeding and dolphins spending too much time at the beach rather than caring for their calves. Regulations were introduced to address this:

  • Only mature females with good survival skills are fed.
  • Males are not fed because they tend to be more aggressive.
  • The dolphins are never fed more than a third of their daily food requirements – they still have to hunt for most of their food.
  • Only fresh local fish hunted by dolphins in the wild are given to them. This is to prevent dolphins from developing preferences for ‘foreign’ foods.
  • To encourage the dolphins to spend more time doing their normal activities, feeding only takes place in the morning.
  • There are no set feeding times so the dolphins do not become conditioned and alter their natural wild behaviour.
  • To avoid stress during feeding the dolphins must not be touched and the fish must be readily available when they want to eat.
  • People are not allowed to feed dolphins from boats, the jetty or the shore. It is illegal to feed dolphins and other wildlife without authorisation anywhere in Western Australia.

Since these regulations were introduced in 1995 only 23% (3 of 13) of calves born to provisioned females have died.

The dolphin experience area

The Monkey Mia Recreation Zone extends in an 800 metre radius around the end of the Monkey Mia jetty. The dolphin experience area is within that zone and is the only place where dolphins are fed.

Boating, swimming and fishing are prohibited in the dolphin experience area. This allows the dolphins to visit without disturbance and enables and Parks and Wildlife rangers to monitor the dolphins’ health.

Spearfishing, netting, water skiing and jet skiing are prohibited in the Monkey Mia Recreation Zone for the safety and well-being of the dolphins. Line fishing is not permitted in the dolphin experience area but is allowed in other parts of the recreation zone.

Regulating boat encounters 

Boat tours from Monkey Mia are subject to strict environmental regulations to ensure minimal impacts on marine animals and ensure the tourism industry remains sustainable. Regulations are necessary as boats can impact dolphin behaviour by:

  • causing dolphins to change travelling directions and speeds
  • splitting up dolphin groups
  • increasing in the number of times dolphins surface for air
  • boat noises interfering with dolphin communications

Dolphins that spend considerable time and energy avoiding boats may leave their preferred hunting, breeding and resting places.

Recruitment of new dolphins

Five dolphins are in the feeding program. 2016 was the first time in 11 years a new dolphin was introduced into the program. Kiya had been going to the beach since she was born in 1997 but was only introduced to the feeding program when one of the old dolphins died.
