Thrill-seeking holiday-makers are putting dolphins at risk

Tourists wanting to watch and swim with dolphins are now being urged to keep their distance in a bid to protect both the animals and the local communities whose livelihoods depend on them.

A study of bottlenose dolphins living off the coast of Zanzibar has found that the many tourist boats operating in the area are harassing the animals, preventing them from resting, feeding and nurturing their young.

The research, led by Dr Per Berggren of Newcastle University, also highlights swimming with dolphins in particular where tourists swim in very close and try to touch the dolphins as being incredibly stressful for the animals.

Printed today in the academic journal Endangered Species Research, the authors say regulation of the dolphin tourism industry is "urgently needed" to minimize the potential long-term negative impact on the animals.

Dr Berggren, who joined Newcastle from Stockholm University earlier this month, explained: "The current situation in Zanzibar is unsustainable. The local community is dependent on tourism - and therefore the dolphins - but unless the activity is regulated the animals will leave.

"Our study found that whenever the tourist boats were present the dolphins were very unsettled and spent less time feeding, socialising or resting. This has a negative impact, not only on individual animals, but on the population as a whole and long term it could be devastating.

"The problem is that any change needs to be tourist-driven. Many visitors will pay drivers extra in tips to steer their boats in close, herding the dolphins so they can dive right in amongst them. Our message is, keep your distance and put the dolphins first."

Dolphin-watching was introduced off the South coast of Zanzibar in 1992. Today it is one of the few places in the world where tourism has completely replaced the traditional dolphin hunt an activity which threatened the local population of around 150 bottlenose dolphins.

"Abolishing the hunts was a major breakthrough and dolphin watching offered a humane, sustainable alternative," says Dr Berggren.

"Unfortunately, without regulation, dolphin tourism brings with it its own challenges."

Watching the dolphins over a period of 40 days, the research team found that in the presence of the tourist boats, the time the dolphins spent resting dropped from 38 per cent of the time to 10 per cent while the time they spent foraging and socialising dropped from 19 and 10 per cent to just 10 and 4 per cent, respectively.

Meanwhile, travelling behaviour more than doubled in proportion, from 33 to 77 per cent, becoming by far the most dominant activity state during interactions with tourist boats.

"Overall, the dolphins are using more energy than they are taking in because they aren't resting or feeding as much but are swimming more as they try to avoid the tourist boats," explains Dr Berggren, based in the School of Marine Science and Technology at Newcastle University.

"Zanzibar is a wonderful place, the dolphins are incredibly interesting and between July and October there are also breeding humpbacks in the area. I would recommend that anyone go there for a holiday and support the local community but act responsibly and ask operators to follow existing guidelines."
