Professional profile

Tobia Pretto is a veterinarian with a position of study, research and experimentation at the IZSVe in the framework of the National reference laboratory for fish, crustacean and molluscs diseases. He graduated in 2009 in Veterinary Medicine at the University of Padua and attended the specialization in “Farming, hygiene, pathology of aquatic species and control of derived products” (2013). At the University of Bologna he attained a PhD in veterinary science (2018).

He is currently involved in the development of vaccination protocols for Vibrio harveyi in sea bass (Interreg Italy-Croatia- AdriAquaNet), the use of innovative diagnostic techniques and drafting of monitoring plans for crayfish plague (A. astaci) (LIFE18 NAT/IT/000806). His research interests are mainly focused on the histopathology of aquatic organisms (fish, crustacean and molluscs) and diagnosis of mycotic and parasitic diseases in freshwater crayfish (Aphanomyces astaci and microsporidiosis). He is involved in pathology and microbiology of ornamental and farmed finfish species. He is also particularly interested in TEM and its use in the diagnosis of viral and parasitic diseases from clinical samples.
