14.00 – 14.15 Opening and welcome by organisers (ESPP, NORCE, NCE Aquaculture, Ragn-Sells)
14.15 – 15.45 Session I.
  • Nutrient flows in aquaculture and fisheries, predicted growth, potentials for circularity and improved nutrient use efficiency
  • Nutrient sustainability as part of aquaculture industry sustainability vision and strategies (industry federations, leading salmon companies)
  • Nutrient flows and recycling in seafood processing waste
15.45 – 16.15 Coffee break
16.15 – 18.00

Parallel session IIA. LCA, circularity business models

Parallel session IIB. Efficiency of use of nutrients in aquaculture feed – aquaculture feed and improved nutrient use efficiency, finding new sustainable feed protein sources as aquaculture grows and wild fish production (so processing by-products) recede, moving from fish-protein based to plant based feeds, possible use of facilitating products (phytase …)

19.30 Networking dinner

11 June 2025
