RASTECH Conference and Trade Fair

Why attend?

RASTECH 2022 is an international technical conference and trade show serving owners and operators of Recirculating Aquaculture Systems (RAS).

Whether it’s raising fish juveniles, producing larger smolt, growing full harvest size fish, aquaponics or research, RAS technology continues to lead the way in the continued expansion of the aquaculture industry around the globe.

As populations rise, so does the demand for seafood. Having already proven its value and efficiencies in the hatchery segment of aquaculture, RAS continues to evolve and develop as one of the most promising farming technologies for raising healthy fish to help meet the world’s growing need for protein.

Who should attend RASTECH?

  • Fish farmers/producers/operators of RAS
  • Fish Hatchery professionals
  • Engineers, contractors and consultants
  • Research and University professionals
  • Investors in RAS

RASTECH 2022 is a capped in-person niche event (limited to 300 RAS professionals). Registration priority is given to the above listed professionals.

Supplier registrations will be refunded (unless they are presenters/speakers or RAS designers/contractors).

ADDRESSING OFF-FLAVOUR

Moderator: David Kuhn, Virginia Tech

Off-flavour compounds (natural compounds such as geosmin and Methyl-Isoborneol [MIB]) can accumulate in recirculating aquaculture systems (RAS). These compounds can accumulate in the water column and into the aquatic species being cultured. This negatively contributes to off-flavours in the products being sold as seafood. Join us as we look at strategies to minimize off-flavor compounds in seafood cultured in RAS.

Speakers:

  • Chris Haughey, Exciton Clean
  • Guillaume Salze, KnipBio
