Shark Tours Boost Later Conservation Action
A two-wave study links snorkeling and free diving with sharks to a 40% higher likelihood of conservation activity, though the evidence is observational.

A study of shark ecotourism participants in Oahu, Hawaii, found that people who snorkeled or free dived with sharks under a marine biologist's guidance were 40% more likely to engage in shark conservation two years later than expected without taking part. The research, published in npj Ocean Sustainability, is a published study rather than a product or policy.
Why it matters
Shark populations have fallen 71% in 50 years, and a third of shark species are now threatened with extinction. The findings suggest experiential tourism may be a measurable lever for conservation behavior, not just an entertainment category.
The study compared tour participants against a public comparison group sampled at Waikiki Beach, surveying each at the time of the tour and again two years later. The reported 40% figure is a relative likelihood, and the findings held after accounting for demographic traits and prior conservation involvement, though the stub does not give absolute rates or sample sizes.
The players
University of Sydney
An Australian research university whose researchers conducted the study on shark ecotourism and conservation behavior.
The details
Participants snorkeled or free dived with sharks while accompanied by a marine biologist, who also surveyed the animals for ongoing research and gave educational information on conservation. Among tour participants, the largest increases were in social media posting, signing petitions, making donations, and advocating for legislation. The design tracks behavior over time, so the result reflects reported conservation activity rather than measured changes in shark populations.
Timeline
Baseline surveys of tour participants and the Waikiki Beach comparison group were conducted around 2024, two years before publication.
Follow-up surveys of both groups were conducted two years after the tour.
Study findings were published on 2 November 2026 in npj Ocean Sustainability.
The Tech Race
The study sits in the conservation-research field rather than a technology race, and the stub names no competing research program or prior milestone to compare against. Its two-wave design with a comparison group is the methodological point of differentiation.
Shark ecotourism is offered in at least 20 countries and draws more than 500,000 people a year, so the findings may apply to a sizable number of travelers. The stub does not give pricing, booking details, or whether tour operators will change their programs in response.
The takeaway
Watch whether follow-up research tests if the 40% effect persists beyond two years and holds across other shark ecotourism operators. The published study in npj Ocean Sustainability is the primary record to track for those results.
