Associate Scientist

Ph.D. 1992, Hebrew University of Jerusalem, Israel
At IOLR since 1985

Research interests:
Studies on the dietary and physiological requirement of essential fatty acids in marine fish larvae. In particular, the function and mechanisms of arachidonic acid (20:4n-6) in the response to acute and chronic stress. Investigating the hormonal and dietary factors involved in the synchronization of metamorphosis of white grouper (Epinephelus aeneus) larvae. Development and commercialization of a microdiet for marine fish larvae
