Amir Sagi

Amir Sagi (; born May 22, 1956) is a professor of life sciences at Ben Gurion University of the Negev, whose field of expertise is crustacean biology, physiology, endocrinology, and functional genomics. He contributed to the study of sexual differentiation, cell growth and aquaculture.

Early life and education Sagi completed his MSc, in oceanography and marine biology at The Hebrew University of Jerusalem which marked the start of his interest in crustacean reproduction strategies. and during his PhD he addressed anatomical and physiological aspects of differentiation in prawns, with special attention to the androgenic gland.

Research and career His postdoctoral training in comparative endocrinology was at the University of Connecticut and the Marine Biological Laboratory at Woods Hole, Massachusetts. under Prof Hans Laufer. Sagi than moved to Ben Gurion University of the Negev (1992) in which he was promoted to the degree of full professor of life sciences (2005), and distinguished professor (since 2018).

He was also president of the International Society for Invertebrate Reproduction and Development (ISIRD) between 2011 and 2013, and held various roles within academic and professional committees such as Dean of the Faculty of Natural Sciences at Ben Gurion University of the Negev (2008–2011) and as a board member of the National Institute for Biotechnology in the Negev. and its associated gene expression in decapods investigating multigenic functions in crustacean reproduction and growth and the establishment of genome editing in prawns using application of CRISPR.

His group established monosex biotechnologies in crustacean culture including the application of temporal RNA interference (RNAi) in the field of aquaculture for all-male culture. Crustacean monosex technologies are applied in Vietnam, Thailand, China, Malaysia, Israel. He is a co-founder of the all-female culture biotech company Enzootic Ltd.

Prawns are efficient predators thus might serve as sustainable and responsible biocontrol agents over various invasive and pest species.
