Dr. Jesus Juario is recognized foe his important contributions in the field of One of those that I included was Dr. Jesus Juario, a Filipino fisheries scientist. Dr. Jesus Villarosa Juario was born on August 6, 1942 in Carcar, Cebu. He is the youngest son in a family of five. He graduated Bachelor of Science in Zoology magna cum laude from the University of San Carlos, Cebu City, in March 1963, and finished his Master of Science in Zoology at the University of Hawaii, U.S.A., in May 1967 through an East-West Center Graduate Scholarship. His Ph.D. degree focused on Biology (Marine Biology) with a grade of "sehr gut" at the University of Hamburg, Germany through a German Academic Exchange Service (Deutscher Akademischer Austauschdienst) Graduate Scholarship in July 1974.As a scientist, Dr. Juario erected one genus and described 11 new species of free-living marine nematodes while working for his doctoral degree at the Institute for Marine Research in Bremerhaven, Germany. Together with other scientists from the Aquaculture Department of the Southeast Asian Fisheries Development Center (SEAFDEC AQD), he developed the technique to capture and transport wild adult milkfish and rear them in captivity. In April 1977, together with Dr. Hiralal Chaudhuri, he spawned for the first time wild adult milkfish in captivity and subsequently confirmed that the fry collected by Delsman in 1929 from Indonesian waters and identified by him as milkfish were indeed milkfish fry. The results of their study were presented in Paimpont, France during the international symposium on the Reproductive Physiology of Fishes (Sept. 19-22, 1977). In the years that followed, he developed together with Ms. Marietta N. Duray, the technique to spawn milkfish, Chanos chanos, in captivity and later on the technique to spawn the siganid, Siganus guttatus, and the sea bass, Lates calcarifer, in captivity and rear the resulting larvae to metamorphosis. This formed as the basis for the development of the milkfish, siganid and seabass hatchery technology at SEAFDEC AQD (1977 – 1986). In 1979, he had a chance to work with Dr. I-Chiu Liao as an exchange scientist at the Tungkang Marine Laboratory in Taiwan on the hatchery of the grey mullet, Mugil cephalus, and with Dr. Ching Ming Kuo in 1980 as an exchange scientist at the Oceanic Institute in Hawaii to work on milkfish hatchery. As a research fellow at the Johannes-Gutenberg University in Mainz, Frankfurt, Germany, he worked with Prof. Dr. R. Reinboth (June to July 1982) on certain aspects of milkfish reproduction and with Prof. Dr. Volker Storch (August to September 1982) of the University of Heidelberg to develop a rapid technique of assessing the nutritional quality of feed/diets through electron microscopy. Together with Prof. Storch and Mr. Helmut Segner, a doctoral candidate, he has shown for the first time through electron microscopy that milkfish larvae could not digest Chlorella, the phytoplankton commonly used at that time together with rotifers to rear milkfish larvae to metamorphosis.
