About IPSF


Indo-Pacific Sea Farms is an aquaculture research and development company located at the Hawaii Ocean Science and Technology (HOST) Park in Kailua-Kona, Hawaii. Our mission is to develop and commercialize innovative technologies for the sustainable production of coral reef fish, plants and invertebrates. The dedicated professionals at IPSF have more than 30 years experience in tropical marine science research and have directed continuous commercial-scale production of marine life products for domestic and international markets for over 20 years. IPSF personnel have worked professionally throughout the United States and in 16 other nations in the Asia-Pacific region. We bring a solid academic base, decades of hands-on field work and a "real-world" perspective to issues involving sustainable use of tropical marine life resources. At Indo-Pacific Sea Farms, innovation is our guiding philosophy!

Favorite Business Quotes:
"The skill in envisioning what type of innovative product a potential set of future buyers may be willing to pay for is what distinguishes market leaders from followers. Such companies need to stay ahead of what customers can imagine. The concept of an innovative product is not something that can be gleaned from today's market research." - Tony Percy, from "On Listening to Customers"

"Compress the cycle. Test, fail, learn, succeed." - Michael Dell

"Almost all innovation comes from small companies." - John Scully

"The sea was angry that day, my friends... like an old man trying to send back soup at a deli." - George Castanza

"Success is falling down nine times and getting up ten." - Jon Bon Jovi

"We may be capable of great things, but life is composed of small things." - Tao Poets

Gerald A. Heslinga, Founder of Indo-Pacific Sea Farms

Gerald HeslingaGerald 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 35 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.

Gerald's work has been funded by Harvard College, the National Geographic Society, the East West Center, the Hawaiian Malacological Society, the U.S. National Oceanic and Atmospheric Administration (NOAA), the University of Hawaii Sea Grant Program, the U.S. Departments of Commerce, Agriculture and Interior, the United Nations Food and Agriculture Organization (UNFAO), the International Centre for Ocean Development (ICOD), the Marine Biotechnology Institute of Japan, Rolex of Geneva, the Australian Centre for International Agricultural Research (ACIAR), the United Nations South Pacific Aquaculture Development Program, the Marine Aquarium Society of North America (MASNA), the International Foundation of Canada and various other public and private sources.
