Dr. Gidon Minkoff

Dr. Gidon Minkoff has dedicated his entire 35-year career to the development of biological and engineering systems for the hatchery production of marine fish juveniles – specifically species new to aquaculture. He studied the biology of rotifers and their mass culture, for which he obtained an MSc in 1984, after which he studied the biology of marine fish larvae for which he obtained a PhD in 1987 from Stirling University.

Since concluding his PhD, he has worked in the private sector while providing invaluable inputs through good relations with the scientific community. His expertise is the accumulation of firsthand experience from multiple projects in which, based on fundamental biological requirements of the organisms to be produced, production systems have been designed and operated. This has encompassed all aspects from design, licensing, construction, budgeting, daily operations, workforce management, and delivery of fish to clients. His work experience encompasses fish species from both warm and cold waters as well as deep-water fish. He also had the opportunity to develop the first production systems for unique fish such as Bluefin tuna, Yellowfin tuna, Sablefish, and Patagonian tooth fish. Gidon also owns his own consulting firm Fish Hatchery Consulting.

SPECIALTIES: Larval rearing of marine finfish, hatchery nursery and growout design, farm trouble shooting.
