Hawaii study links tourism to declining spinner dolphin calf numbers
Researchers found only about 9% of the dolphins studied were calves, far below the expected 17%, and said tourism may be limiting recovery.
- A new study by the University and Marine Mammal Research Program, published in Endangered Species Research, suggests tourism off Hawaii Island contributes to low spinner dolphin calf numbers, finding about 9% compared to an expected 17%.
- Spinner dolphins fish at night and rest in bays during the day, when tourism encounters occur during critical resting periods likely affecting reproductive success and calf survival.
- Scientists utilized drone photography and age-length data from researcher Kristi West at the Health and Stranding Lab to create the first growth curve, categorizing dolphins into calves under 2, juveniles, and adults.
- Experts from the Marine Mammal Commission and the Pacific Scientific Review Group argue current federal rules requiring boats to stay at least 50 yards away are insufficient, advocating for "time-area closures."
- While dolphin tourism generates more than $100 million annually, Randall Wells of Brookfield Zoo Chicago emphasizes balancing economic activity with ecological health to protect dolphins valued at more than $3.3 million.
