Sampling of the targeted fish species

The sampling of marine fish has been done according to the sampling scheme established by one of the partners (ANSES Maisons-Alfort) and thanks to the participation of the different partners to the research scientific Ifremer campaigns. Fish have also been sampled via fishermen or wholesale merchants.

In total, 9 members of the Fish-Parasites network got on board during 7 Ifremer campaigns for a total of 115 days at sea and 817 sampled fish. To complete this sampling, 969 marine fish were also collected from wholesale merchants or fishermen.

In total, 1786 marine fish were sampled by the Fish-Parasites network over a 30-months period.

Moreover, 138 freshwater fish (62 from the Geneva lake, 51 from the Bourget lake and 25 from the Annecy lake) as well as 1026 perch fillets (950 from the Geneva lake and 76 from the Annecy lake) were examined for the presence of Diphyllobothrium parasites (also known as the fish tapeworm).
