About

Established on January 2008, our lab is affiliated with the Department of Poultry and Aquaculture, within the Institute of Animal Science, The Agricultural Research Organization.

We are located at the main campus of the Volcani Center, Rishon LeZion.

Vision

We seek to explore uncharacterized areas in the biology of fish, in order to better understand their unique characteristics and to advance the fields of aquaculture, fisheries, and conservation.

 

Funding

Our research is supported by various sources of funding:

  • NSF-BSF (National Science Foundation and  Binational Science Foundation).

  • BARD (US-Israel Binational Agricultural Research and Development Fund).

  • The Chief Scientist of the Ministry of Agriculture & Rural Development.

  • ISF (Israel Science Foundation).

  • Israeli-French High Council for Scientific & Technological Research.
