Workshop

4th International Fish Microbiota Workshop

The fourth International Fish Microbiota workshop will be held in Wageningen, Gelderland, the Netherlands, September 6th-8th, 2023

Organised by Aquaculture and Fisheries, Host Microbe Interactomics
Date

Wed 6 September 2023 until Fri 8 September 2023

Venue Fletcher Hotel-Restaurant De Wageningsche Berg

Building on the successes of the first, second and third microbiota workshops held in Trondheim (Norway), Eugene (Oregon, US) and China (online) respectively, we are happy to announce that the fourth International Fish Microbiota Workshop will be held in Wageningen (the Netherlands) by the team of Wageningen University and Research (Aquaculture and Fisheries group and the Host-Microbe Interactomics group).

This meeting brings together scientists from around the world interested in the fish health and disease and in particular in the interactions between the fish and their associated microbes. The meeting will consist of two days of oral and poster presentations focusing on topics related to fish microbiota and immune responses and fish health, dietary changes, microbial colonization and community assembly, and the use of model species to study host-microbe interactions. Furthermore, an extra day (funded by the IPAMA project - International Partnership for Advancing Microbiome-informed Aquaculture, Norwegian Research Council) will be added to the programme with focus on Microbiome monitoring, management and manipulation: opportunities and challenges in commercial aquaculture. This day is specifically targeted at fish health in aquaculture, featuring discussions on pre-, pro- and symbiotics, and the future of microbiome research in the context of the One Health approach.

Themes

  • Microbial colonization
  • Microbial community assembly
  • Model species
  • Microbial Management in aquaculture
  • Host-microbe interactions
  • Nutrition, feeds and fish microbiota
  • Health, immunity and fish microbiota
