Fiz has experience in bivalve aquaculture, nutrition and selective breeding.
Fiz holds a PhD in Marine Biology and Aquaculture by University of Santiago de Compostela (USC, Spain), a Postgraduate degree in Fisheries Economy (USC), and a Postgraduate degree in Advanced Methods for Applied Statistics (UNED, Spain).
He started his research career in 2002 with a predoctoral fellowship to investigate razor clam culture at Centro de Investigacións Mariñas at Ribadeo (CIMA, Spain). Fiz studied the microbiological aspects of larval rearing in the clam Ruditapes decussatus at University of A Coruña (UdC, Spain) and CIMA.
Fiz pursued his postdoctoral training (2012-2014) at Institut Français de Recherche pour l'Exploitation de la Mer (Ifremer, France), where he studied the effect of live diets on Crassostrea gigas larval development with a biochemical approach.
From February 2014 to August 2017 he worked as Research and Development (R&D) engineer at the French commercial hatchery Novostrea Bretagne. Fiz developed a selection breeding program for summer mortality in C. gigas, diversified the production of cultured species in this hatchery and optimized hatchery and nursery culture.
He joined Oceano Fresco team in September 2017.
