Abstract:

Wild dolphin-swim tourism has grown in specific locations where Hawaiian spinner dolphins (Stenella longirostris) have known resting habitat. The increased growth in dolphin-swim businesses has created an industry in Hawaii that earns an estimated $102 million (USD) annually in 2013. Semi-structured interviews with business owners, market research, and boat-based observations provide a platform for estimating revenue generated from dolphin tourism in two popular locations, Waianae, Oahu and Kailua-Kona, Hawaii Island. A revenue analysis of dolphin-swim tourism is presented using a peak season and utilization rate model. These predictions offer an accountability exercise based on a series of assumptions regarding wild dolphin-swim demand and an annual estimate of the number of viewing participants and revenue earned. The results show that dolphin viewing companies are making a larger profit than dolphin-swim businesses by approximately $19 million (USD) per year, however, both avenues are generating large earnings. Sizable differences between businesses in Kona and Waianae are discussed. The average lifetime revenue generated by a dolphin in 2013 is estimated at $3,364,316 (USD) for Waianae and $1,608,882 (USD) for Kona, and is presented as a first step in scenario analysis for policy makers looking to implement management in the bays where tourism occurs. This study offers the first revenue estimates of spinner dolphin tourism in Hawaii, which can provide context for further discussion on the impact and economic role of the dolphin-swim industry in the state.

Excerpts from University of Hawaii at Manoa press release:

“What surprised us was the study showed that dolphin viewing companies are making a larger profit than dolphin-swim businesses by an estimated $19 million per year,” said Carlie Wiener, PhD, University of Hawaiʻi Mānoa’s and lead-author of the study. “There are sizable differences between businesses in Kona and Waiʻanae, which has significant impacts for how these businesses are managed. We see this paper as a first step for policy makers looking to implement management in areas where tourism occurs and can provide context for further discussion on the ecological impact and economic role of the dolphin-swim industry in the state. We need to take into account protection for the dolphins, but also the livelihoods of the tour operators.”


These observations have important considerations as the state of Hawaiʻi considers new regulations and management of the dolphin-tourism industry and offers resource managers a way of planning for future growth and risk assessment of a previously underestimated component of the marine tourism industry in Hawaiʻi.


“NOAA is currently evaluating management options for the protection of spinner dolphins in Hawaiʻi,” said Lars Bejder, PhD, an associate researcher at the University of Hawaiʻi Mānoa’s Hawaiʻi Institute of Marine Biology (HIMB) and co-author of study. “This is particularly important given that recent research has identified that spinner dolphins in resting bays off the Kona coast have the highest exposure rates to human activities anywhere in the world (information available here: https://royalsocietypublishing.org/doi/10.1098/rsos.171506 and https://www.cnn.com/travel/article/swimming-with-spinner-dolphins-hawaii-island/index.html). High exposure rates to humans within critical habitats is cause for concern for the long-term viability of the dolphins and hence the dolphin-tourism industry. It is paramount that appropriate regulations are implemented to ensure long-term sustainability.”
