Tourists who took part in a shark ecotourism tour in Oahu, Hawaii, were 40% more likely to engage in shark conservation efforts two years later than expected without taking part. The findings were published in npj Ocean Sustainability.
Why it matters
Shark populations have declined by 71% over the last 50 years, and a third of shark species are now threatened with extinction. The study suggests that experiential ecotourism may be a useful tool for building public support for conservation.
The evidence comes from a two-year follow-up survey comparing tour participants with a Waikiki Beach comparison group, showing participants were 40% more likely to engage in conservation than expected without taking part. The sample sizes and the duration of the effect beyond two years are not specified in the available findings.
The players
University of Sydney
The University of Sydney is a major Australian public research university whose researchers conducted the study.
The details
Researchers surveyed tourists who snorkeled or free dived with sharks on an Oahu tour led by a marine biologist, along with members of the public sampled from Waikiki Beach. Among tour participants, the largest increases were in posting on social media, signing petitions, making donations, and advocating for legislation.
Timeline
Approximately 2024: Baseline surveys of tour participants and the Waikiki Beach comparison group were conducted.
Two years after the tour: Both groups were surveyed again on their conservation activity.
November 2, 2026: Study findings were published in npj Ocean Sustainability.
The Big Picture
Shark ecotourism is offered in at least 20 countries and draws more than 500,000 people a year into interactive activities with sharks and rays. This study adds evidence that such experiences may translate into lasting conservation behavior, not only short-term enthusiasm.
Travelers considering shark encounters can choose operators that include conservation education and guided by marine biologists. Engaging with conservation through social media, petitions, or donations is among the actions participants most often increased.
The takeaway
Hands-on contact with wildlife can turn curiosity into sustained support for conservation. Choosing educational, research-linked ecotourism is one practical way to help protect ocean species.
