VIVALDI will contribute to the implementation of European Union policy concerning aquatic animal health, including specific measures to control increased mortality in Pacific oyster in connection with the detection of a herpes virus (OsHV-1). The goal of the Dutch partners in VIVALDI is to estimate genetic parameters for disease resistance or tolerance in the Pacific oyster and investigate the impact of nutritional factors on a breeding program for cupped oysters at commercial hatchery level. Using DNA parentage assignment in mixed families Genetic X Diet interaction of survival is estimated. This is done in controlled and field conditions. Pedigree will be established by using SNP panels developed by other partners in the project. Other parts of VIVALDI that are of interest for the Netherlands are Studying pathogen diversity and improving tools for better surveillance, Understanding marine bivalve functional response for alternative methods of prevention and treatment, Microbiota as Bioindicators of bivalve Health, Monitoring of key factors associated with surviving capacity of bivalve during mortality events, Effects of environmental parameters and environmental stressors on pathogen transmission and related mortality outbreaks, Role of plankton as vectors and consequences on pathogen physiology, and impact on zootechnology and epidemiology, Pathogen dissemination and disease transmission modelling in marine ecosystems, Disease management measures and biosecurity,
The overarching goal of VIVALDI is to increase the sustainability and competitiveness of the European shellfish industry by improving the understanding of bivalve diseases and by developing innovative solutions and tools for the prevention, control and mitigation of the major pathogens
affecting the main European farmed shellfish species: Pacific oyster (Magellana gigas), mussels (Mytilus edulis and M. galloprovincialis), European flat oyster (Ostrea edulis), clams (Venerupis philippinarum) and scallops (Pecten maximus). The project addresses the most harmful pathogens affecting either one or more of these shellfish species: the virus Ostreid herpesvirus 1 (OsHV-1),Vibrio species including V. aestuarianus, V. splendidus, V. harveyi and V. tapetis, as well as microeukaryotes such as the parasites Perkinsus olseni and Bonamia ostreae.
