Geert Wiegertjes is professor of the Aquaculture and Fisheries group at Wageningen University & Research, the Netherlands. As head of the group, his scientific interest in the interaction between fish nutrition and health in aquaculture has broadened, to also play a supporting role for research on fisheries ecology.

In his recent TEDx talk he underscores the need for a sustainable production of fish and shellfish products in a world where demands for seafood are rising rapidly. While unravelling critical factors limiting aquaculture and seafood production, he calls to respect biodiversity, animal health and welfare. Geert Wiegertjes has been project coordinator and/or training coordinator of three MSCA training networks (FP5, FP7) and work package leader of Imaquanim (FP6), ParaFishControl (H2020) and currently, AQUA-FAANG (H2020). He coordinated TargetFish (FP7), one of the larger research consortia on fish health and vaccination.
