Extension Specialist (Retired)

Areas of Interest

Aquaculture, Aquaponics, hydroponics, sustainable agriculture

Dr. Clyde S. Tamaru, Ph.D. is born and raised in Hawaii and a home grown product of the Hawaii public school system. He attended Royal Elementary School, Central Intermediate and would graduate from McKinley High School. He obtained a BS in Biology and an MS in Zoology from the University of Hawaii at Manoa. He received his doctorate from the University of Tokyo, Faculty of Agriculture Department of Fisheries.  He is currently is an aquaculture specialist with the College of Tropical Agriculture and Human Resources (CTAHR) in the Department of Molecular Biosciences and Bioengineering and has been a non tenure track faculty member of the University of Hawaii at Manoa since 1995. Dr. Tamaru heads CTAHR’s aquaculture extension team that provides technical assistance in aquaculture and aquaponics to private and public sector stakeholders within the state and abroad. The information and assistance is science based and accomplished by maintaining an active research portfolio that covers Hawaiian Fishponds, biofuel byproduct remediation, aquaponics, and developing hatchery technologies for a variety of freshwater and marine species. The overall goal of the research and extension efforts are to decrease Hawaii’s dependence on imports for both food and energy. His other interests include developing culture based curriculum for use in Hawaii’s school systems.
