“…Phaeopigments were relatively high in water collected from mesocosms with buffer addition, which is consistent with lower growth rates in these treatments if high detritus was present from food addition/buffer interaction. If total suspended solid concentrations get too high, ingestion rates can decrease regardless of phytoplankton concentration ( Gray and Langdon, 2018 ) and have a large influence on oyster condition ( Saraiva et al, 2020 ).…”

“…daily or weekly) so can be a useful way of exploring the potential physiological impact of variable environmental conditions, and this makes it useful for assessing production potential at different farm locations. The DEB modelling approach has been used to simulate the life cycle of many different animals including sea cucumbers (Ren et al, 2017), sea urchins (Yeruham et al, 2019), Sea Bass (Stavrakidis-Zachou et al, 2019 , and is an established approach for modelling bivalve growth and shellfish production potential (Bacher and Hatzonikolakis et al, 2017;Palmer et al, 2020;Saraiva et al, 2020).…”

This study was founded by the University of Stirling and by the International Marine Centre (IMC), and is part of the Sardinian project "OSTRINNOVA, Valorisation of sustainable production of oysters in the shellfish production system in Sardinia", funded by the Sardinia Region, Det. DG n ° 566 of 27/04/2016. My first thank goes to my Stirling university and International Marine Centre (IMC) supervisors, Stefano Carboni, Trevor Telfer, Maura Baroli and Stefano Guerzoni, for giving me the opportunity to carry out this important step of my life. In particular, I want to thank Stefano Carboni, who brought me into the field of aquaculture research, thanks to whom I first took a master's degree in this field and then increased my skills performing this PhD study. He was a source of motivation and he always gave me great advice on how to handle all the problems encountered during this PhD study. I would like to tanks Alessandro Gorla and Francesca Gargiulli and all the staff of the Compagnia Ostricola Mediterranea in the San Teodoro lagoon, for the hospitality, help and availability during the field work. Alessandro and Francesca, played a very important key role for the good development of this PhD thesis. They have become friends as well as List of figures 8 List of tables 12 List of abbreviations

“…Over the last 2 decades, numerical modelling tools coupling ecophysiology based on the dynamic energy budget (DEB) theory and environmental forcings based on field monitoring or physical− biogeochemical models have been widely implemented to explore the growth of bivalves or the productivity and carrying capacity of bivalve farming under varying local environments (Maar et al 2015, Lavaud et al 2020, Palmer et al 2020, Pete et al 2020, Saraiva et al 2020, Taylor et al 2021. DEB models simulate numerous ecophysiological functions of individuals, such as growth, spawning, food uptake, respiration, or egestion, as a function of environmental forcings, and may be extrapolated to farmed or wild populations using box models (e.g.…”

Low trophic aquaculture (LTA), such as bivalve farming, offers promising avenues to supply sustainable seafood and aquafeed. While bivalve farming usually occurs in highly productive coastal areas which already support numerous human activities and suffer from environmental pressures, numerical tools offer a promising avenue to explore and assess biomass production potential and associated ecosystemic impacts for further development of the industry and prospection of new exploitation sites. In this study, we coupled an ecophysiological model, the dynamic energy budget theory (DEB), with an ecosystem model (NORWECOM.E2E) to simulate blue mussel Mytilus spp. farming production and effects based on the food web in the mesotrophic Hardangerfjord in western Norway. We tested several levels of fjord-scale farming intensity and assessed 2 production purposes: aquafeed and human consumption. Results suggested the Hardangerfjord could host large-scale mussel farming for both purposes. However, large exploitation schemes displayed detrimental effects on individual mussel growth (39% less wet mass after 2 yr) and especially on secondary production (decrease of 33% after 1 yr) due to acute trophic competition. Simulations showed short production cycles for aquafeed were more efficient to exploit primary production, since young and small mussels have lower maintenance and reproduction costs. Dissolved nutrient inputs from salmonid farms had marginal effects on primary production (<2%). However, salmonid and mussel farming activities could compete for the sites with the highest production potential.
