“…Comparison with other ES studies in shell sh species is di cult due to differences in the metrics used. Compared to the present results for Paci c oyster farming (i.e., 3.05 kg N tonne P.oyster -1 , 0.95 kg P tonne P.oyster -1 and 75.02 kg C tonne P.oyster -1 ), a study conducted on blue mussels showed higher nutrient removal potential (i.e., 5.0 -8.5 kg N tonne mussel -1 and 0.43 -0.95 kg P tonne mussel -1 ) and similar C sequestration potential (i.e., 74.7-77.5 kg C tonne mussel -1 ) [30]. Due to resource limitations, only nutrient removal, and C sequestration processes associated with oyster farming were investigated in this study.…”

Sustainable food production that meets consumer demands while reducing environmental impacts is a critical societal challenge. The seafood industry, including shellfish aquaculture, is considered a key segment for future protein supplies. Like all food production sectors, environmental impacts of the "blue food” sector are a key consideration. The present study demonstrated that Irish Pacific oyster (Magallana gigas) farming has relatively low environmental impacts (i.e., 100-year global warming potential of 373.86 kg CO2 eq. tonne-1; acidification potential of 1.33 kg SO2 eq. tonne-1; and eutrophication potential of 0.39 kg PO4 eq. tonne-1) compared to other seafood and terrestrial animal sectors. Using ecosystem services metrics, one tonne of fresh harvested oysters can remove, on average, 3.05 tonnes of nitrogen, 0.35 tonnes of phosphorus, and sequester 70.52 tonnes of carbon from the environment, thus potentially acting as a nutrient remediator and a potential short-term carbon sink. These findings show how oysters can offer a sustainable food source and provide local environmental benefits. The study also points to future work which could further improve ecosystem services modelling for this food source.

“…The model output includes estimates of FW, DM, and N-, and Ptissue concentrations, where DM, N, and P contents of mussels are assumed to be a constant fraction of the mussel FW of 10.3%, 1.45%, and 0.083%, respectively 94 . In addition, we estimated the C removal in mussel shells as 4.61% of FW 96 . Mussels sequester CO 2 into insoluble and indigestible calcium carbonate of the shells, which was assumed to act as a carbon sink 15 .…”

Multi-use of offshore wind farms with low-trophic aquaculture could provide sustainable energy, nutritious seafood, and restorative ecosystem services through nutrients and carbon capture and utilization. In a transition zone between marine and brackish seas, our model predicted that allocating 10% of projected wind farm areas to blue mussel and sugar kelp aquaculture in the North Sea - Baltic Sea transition zone could yield 18 t-fresh weight ha−1 yr−1. Total carbon captured and harvested from seaweed biomass and mussel shells would equal 40% of the carbon dioxide emissions from the Danish agricultural sector. Furthermore, global aquaculture production is projected to increase by 132% compared to current production. With technological and regulatory challenges still to be addressed, these findings demonstrate a vast potential of multi-use in offshore areas, which can generate blue biomass with fewer user conflicts, while mitigating eutrophication and climate change, thereby supporting multiple global sustainable development goals.

“…However, offsetting is complex, and there are many knowledge gaps that still need to be addressed, particularly in the case of carbon 142,199 . One of the challenges is that assimilation depends upon the species, location, culture method, and time of year 200–202 . Therefore, it is difficult to assign simple fixed values, as this approach may over‐ or under‐estimate the nutrients or carbon removed by a particular operation.…”

Understanding the transfer of nutrients or carbon from the environment to the farmed species is of fundamental importance for accounting purposes, but it is also important to determine the fate of the nutrients and carbon to ensure these are removed from the system and not just converted into another form and released back into the environment (e.g., respired or excreted).…”

Marine aquaculture has the potential to increase its contribution to the global food system and provide valuable ecosystem services, but appropriate planning, licensing and regulation systems must be in place to enable sustainable development. At present, approaches vary considerably throughout the world, and several national and regional investigations have highlighted the need for reforms if marine aquaculture is to fulfil its potential. This article aims to map and evaluate the challenges of planning and licensing for growth of sustainable marine aquaculture. Despite the range of species, production systems and circumstances, this study found a number of common themes in the literature; complicated and fragmented approaches to planning and
