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

| 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 …)

Site visits description
Marineholmen RASLab is a research and innovation company with a focus on Recirculating Aquaculture System (RAS) technology. With a central location in Bergen, and a state-of-the-art research facility, RASLab offers the opportunity for the investigation of sustainable, land-based fish farming. In the EU project INNOAQUA, RASLab is hosting the first stage of Demo #1: the integration of salmon production in RAS with microalgae production in a photobioreactor (PBR) at pilot scale, in a land-based IMTA (Integrated MultiTrophic Aquaculture) set-up. During the site visit, you will be given a tour of the whole facility and explain more about the research and show you 12 self-contained fresh or saltwater RAS systems. One of these is connected to a microalgae PBR from the partner NORCE, where the microalgae are continuously fertilized with the nutrient-rich effluent water from the RAS, producing valuable microalgal biomass while cleaning the water.
Note: this visit can only host 20 persons, due to limitations in the space and lay-out of the facilities! So be quick to sign up! The location is a 5 min walk from the venue where the workshop is held.

The National Algaepilot Mongstad is a state-of-the-art research facility dedicated to the development and demonstration of sustainable production processes of microalgae (TRL 5-6), as well as for the production of large quantities (100’s of kilos) of microalgal biomass for further testing and development of new products (food, feed, chemicals). For example, in the INNOAQUA project, around 200 kg of microalgal paste of three different microalgae strains were produced, that are now tested in a biorefinery approach to extract various ingredients (e.g., omega-3 rich oils, proteins, pigments) that are used for food formulation. The facility consists of a greenhouse with various types of photobioreactors, and a basic laboratory and office as well as the related infrastructure (water treatment, harvesting equipment) in the annex, and is owned by the University of Bergen, and operated in close collaboration with NORCE. During the visit, you will have the opportunity to tour the facilities, and gain insights into our research initiatives and technological advancements.
The facility is located at industry park Mongstad, approximately one hour north-west from Bergen. We will travel to the facility by bus, leaving at 09h00 from Marineholmen (Thormøhlensgate 55, 5006) in Bergen, back around 12h30. Fare for the visit is 20€.
