Biography
Dr. Dan Margulies joined the IATTC staff in 1988 as Senior Scientist. He is a member of the Biology Program and leads the Early Life History Group since 1997. This group studies the egg, larval and early-juvenile stages of tunas and investigates the environmental and biological factors that influence pre-recruit growth and survival. The ultimate goal of this research is to understand the influence of pre-recruit survival dynamics on recruitment fluctuations in tunas. Dan’s responsibilities include the coordination of the early life history research activities at the Achotines Laboratory in Panama. This research includes field and laboratory studies of the reproductive biology of adult tunas and the ecology and physiology of larval and early-juvenile tunas. Dan also serves as principal scientist for collaborative research projects between the Early Life History Group and international universities and research organizations.
