Marine and/or terrestrial transportation and storage of live seafood is an inevitable step in the food producer-consumer chain. Current technologies are not sufficiently sustainable as they suffer from high mortality, low stocking densities and quality losses of the food upon prolonged transportation and storage periods, that makes live seafood inaccessible for many potential customers and markets. The main reason for the above described limitations is the accumulation of a toxic metabolite (non-ionic ammonia, NH3(aq)) in water during the transportation and storage of the live seafood, even at low temperatures. This project aims at the development of novel systems for seafood transportation and storage which are based on a physical-chemical technology that has been previously developed and tested for fish production in recirculating aquaculture systems. The technology will be adapted to ensure high-density autonomous operation for >4 weeks without jeopardizing the products.
