Join a Shark Research Institute expedition in Hawaii to assist with research on tiger sharks!

May 2022


Two expeditions will be led by Charlie Fasano, SRI Regional Director-Hawaii. Citizen scientists participate in cataloging individual tiger sharks. The objective is to determine tiger sharks’ annual use of the area. The project will also increase the biological information available to guide conservation efforts for this species, on both a regional (Hawaiian) and global scale, with important data such as life history, species distribution, abundance and diversity, population productivity, and extinction risk. This information will then be used to inform international conservation forums such as CITES, as well as local fishery risk assessment and management plans. An education and awareness campaign on the status of Hawaii tiger sharks will be conducted in conjunction with the survey to increase awareness of the habitat use of the species.




The expedition includes daily boat dives to catalog resident tiger sharks of Big Island, Hawaii and a guided tour of Puʻukoholā Heiau National Historic Site.

Nitrox is available and required.

Expedition Mua:  May 5, 6, 7, (8)

The advantage of staying at this resort is that the vessel will be picking us up at the pier in front of the resort. You literally walk from your room, pass the resort pool, and unto the boat. When we return, you disembark the vessel and again walk past the resort pool directly to your room.
Also, the resort is located on the quiet northern end of the obligatory walking street of Ali’i Dr. with its cafes, shops, restaurants, etc. and is operated by Courtyard by Marriott. It is located away from the noisy bars of the southern end of Ali’i Dr.
