Dr. Papandroulakis completed his doctoral thesis under Prof M. Kentouri studying the feeding requirements of the seabream (Sparus aurata) during the larval stages and developing mathematical models of food consumption and growth in order to understand and describe the implicated biological mechanisms and to develop an automated management and feeding system in hatcheries applying a fuzzy controller. He holds a master’s degree in Theoretical Physics and a bachelor’s degree in Physics from the University of Crete, Greece.
Dr. Papandroulakis worked as specialized research scientist at the Aquaculture Dept of the Institute of Marine Biology of Crete and is scientific responsible of the intensive hatchery facility since 1993, aiming the improvement of methodologies and technologies applied, studying more than 15 different species. He is particularly interested in the specific diversification of the aquaculture production emphasizing on the fast growing species both benthic like the wreckfish (Polyprion americanus), for which the control of its reproduction in captivity was succeeded for first time and the greater amberjack (Seriola dumerili) for which successful methods for larval rearing are developed. Recently these studies have been extended on the development of appropriate methodologies for the larval rearing of the blue fin tuna (Thunnus thynnus).
Dr Papandroulakis has initiated the pilot scale net pen cage farm of the Institute at Souda bay (west Crete) in 2000 and is the scientific responsible for its operation since then. Among his interests are also issues related to technology transfer and the application of research results in the industry. He was founder of the spin â€“ off company â€śAqua Biotech Hellenic SAâ€ť and member of the Board of Directors from 2002 to 2007.
Dr Papandroulakis has participated since 2000 in 18 research projects (9 European), in 8 of which was the scientific responsible at HCMR. He has participated in 19 Conferences and Workshops (7 as invited speaker). He is lecturing on â€ślarval rearing techniquesâ€ť, “Species Diversification in the Mediterranean Aquacultureâ€ť and “Automation in Aquacultureâ€ť since 2003 at the University Master Course in Aquaculture organized by the University of Las Palmas de Gran Canaria, the Canarian Institute of Marine Science (ICCM) and the Mediterranean Agronomic Institute of Zaragoza (CIHEAM) and at the University PhD Course in Aquaculture organized by the University of Las Palmas de Gran Canaria. He has supervised 9 Degree Thesis (5 Greece, 2 UK, 1 Portugal, 1 Spain) 6 Master Thesis (1 Mexico, 1 France, 2 Greek, 1 Spain, 1 The Netherlands) and was member of the Evaluating Committee in 2 European and a Greek PhD Thesis (University of Granada, University of Las Palmas de Gran Canaria, University of Crete)

Dr. Papandroulakis research was initially focused on the improvement of methodologies and technologies for intensive and semi-intensive larval rearing of fish studying more than 15 different species (since 1991), and the study of their feeding requirements. This study is extended with the development of mathematical models of food consumption and growth in order to understand and describe the implicated biological mechanisms aiming the development of automated management and feeding systems in hatcheries and cage farms. Since 2000 he is interested in the specific diversification of aquaculture production emphasizing on the fast growing species both benthic like the wreckfish (Polyprion americanus), for which for first time the successful control of its reproduction in captivity was achieved and the greater amberjack (Seriola dumerili) for which successful methods for larval rearing are developed. Recently he is involved in the development of appropriate methodologies for the larval rearing of the blue fin tuna (Thunnus thynnus). Among his interests are issues related to technology transfer and the application of research results in the industry and especially the hatchery technologies of the Mesocosm type in Mediterranean SMEs for the specific diversification of production (since 1999).
