Gerald Heslinga is a marine biologist who conducts applied research on the reproduction and developmental biology of tropical marine organisms. The emphasis of his work during the past 31 years has been on captive breeding of marine invertebrates, primarily echinoderms (starfish and sea urchins), molluscs (clams, snails and oysters) and cnidarians (corals, jellyfish and sea anemones). Gerald is best known for his pioneering research on the reproductive biology and mass culture of giant tridacnid clams in Palau, as principal investigator at the MMDC Giant Clam Hatchery during the 15-year period from 1981 through 1995. Innovative techniques and experimental results developed by Gerald and his research team at Palau have been widely disseminated among tropical Pacific nations and have positively affected Pacific coral reef conservation efforts, sustainable seafood production and the culture of reef organisms for ornamental and educational markets.

Gerald's work as founder and owner of Indo-Pacific Sea Farms in Hawaii is focused on the breeding and marketing of photo-symbiotic reef organisms such as tridacnid clams, alcyonacean and scleractinian corals. Recent applied research involves the culture of micro-invertebrates, ooze-dwelling detritivores, beneficial bacteria, planktonic feeds and various ornamental marine algal forms. Now in its twelfth year of operation on Hawaii's Kona coast, Indo-Pacific Sea Farms is recognized as an international leader in the development of environmentally sound approaches to the production and husbandry of beneficial marine organisms.

Gerald has been active in regional Pacific organizations such as the University of Hawaii's Pacific Aquaculture Association and the Oceanic Institute's Center for Tropical and Subtropical Aquaculture. He and his wife Kyoko have two daughters, Olivia and Lisa. In his spare time Gerald is a coach with Kailua-Kona's youth soccer programs.


Gerald is a 1976 Honors graduate of Harvard College and was a Graduate Fellow from 1976 to 1981 at the Resource Systems Institute of the University of Hawaii's East West Center.

He has conducted research at Harvard's Museum of Comparative Zoology (MCZ), the Environmental Systems Laboratory (ESL) at Woods Hole Oceanographic Institute (WHOI), the University of Hawaii Department of Zoology, the University of Guam Marine Laboratory, the Micronesian Mariculture Demonstration Center (MMDC) in the Republic of Palau and the Natural Energy Laboratory of Hawaii. He has lectured at Harvard, the Woods Hole Oceanographic Institute, the University of Hawaii, the University of the Philippines, James Cook University of Australia, the Scripps Institute of Oceanography and the Marine Biotechnology Institute of Japan, as well as at numerous national and international marine science conferences. He has conducted international professional consultancies in Japan, Australia, the Philippines, Papua New Guinea, Fiji, the Solomon Islands, the Marshall Islands, the Federated States of Micronesia (Yap, Chuuk, Pohnpei and Kosrae), as well as at Guam, Saipan and Palau.
