Overview
Sophie is a PhD student at the University of Exeter, working in collaboration with the MBA and Cefas. Her project, “Evaluating and maximising the environmental benefits of seaweed farming in the Southwest”, focuses on quantifying the habitat value and biodiversity supported by seaweed farms. The aim of this work is to inform the regulation and development of ecosystem-based approaches to aid in the expansion of seaweed cultivation around the UK.
Previously, Sophie studied MSci Marine Biology at the University of Exeter, where she conducted diverse research projects on the effects of clutch relocation on loggerhead sea turtles, and the development of a low-cost in situ method to quantify estuarine-air CO2 fluxes. After graduating, Sophie worked as a research assistant on the Atlantic Meridional Transect Ocean Flux from Satellite Campaign (AMT4OceanSatFlux) funded by the European Space Agency. This project estimated Atlantic Ocean CO2 exchange using satellite and in situ data to enhance monitoring and validate current predictions of the ocean carbon sink. Outside of academia, Sophie is passionate about science communication and wildlife film making.

Research projects
Project Title: Evaluating and maximising the environmental benefits of seaweed farming (mariculture)
Supervisors: Prof. Charles Tyler, Dr. Ross Brown, Dr. Ian Ashton, Dr. Dan Smale (MBA), Prof. Grant Stentiford (CEFAS), Dr. David Bass (CEFAS)
Funding Bodies: College of Life and Environmental Sciences, Marine Biological Association (MBA), Centre for Environment, Fisheries and Aquaculture Science (CEFAS), The Worshipful Company of Fishmongers’ Fisheries Charitable Trust
Project Description: Sophie is a PhD student at the University of Exeter. Her research aims to investigate the benefits of commercial seaweed farming for enhancing local biodiversity and environmental conditions, in the South West UK. She will identify the potential of farms to create spawning and nursery habitats, assess the invertebrate communities they support, and monitor how farms influence physical conditions and dissolved nutrient chemistry. Sophie hopes to understand and maximise the potential of seaweed as a sustainable food source for the future growth of the industry. Her PhD is in partnership with the Marine Biological Association (MBA), the Centre for Environment Fisheries and Aquaculture Services (CEFAS), SWEEP, the Fishmonger’s Charitable Trust and the Cornish Seaweed Company. Sophie will be conducting field work at a Cornish Seaweed Company’s farm in Cornwall working alongside the company to maximise benefits for both their harvest and the local environment.

Abstract:
Quantifying habitat provisioning at macroalgal cultivation sites
AbstractMacroalgal cultivation is expanding rapidly, and promises to contribute significantly towards future food and energy security, sustainable livelihoods, ecosystem services and habitat provisioning for a range of associated organisms globally. Habitat provisioning underpins biodiversity and ecosystem structure and functioning, supports many ecosystem services and has possible benefits to other marine industries, including enhancement of commercial fish stocks. In macroalgal cultivation, however, only recently has habitat provisioning started to be assessed at a local scale (within a farm's footprint) and with a range of different approaches. This review evaluates techniques used to quantify habitat provisioning in and around macroalgal cultivation sites, for species ranging from microorganisms to megafauna, and outlines recommendations to enable a more comprehensive ecological valuation of macroalgal cultivation in the future. The majority of information on biodiversity associated with macroalgal cultivation is associated with quantifying biofouling or pest organisms, rather than the contribution of colonising species to healthy ecosystem functioning. We suggest how better monitoring of macroalgal cultivation could enable an ecosystem approach to aquaculture (EAA) in the future. To achieve this, we highlight the need for standardised and robust methods for quantifying habitat provisioning that will enable assessment and monitoring of macroalgal cultivation sites of varying scales and within different regions and environmental settings. Increased evidence for the potential habitat value of macroalgal cultivation sites will help inform and shape marine legislation, licencing and certification for macroalgal farmers and potentially reduce marine user conflicts, helping the industry to continue to grow sustainably using EAA.

Abstract:
Development and Diversity of Epibiont Assemblages on Cultivated Sugar Kelp (Saccharina latissima) in Relation to Farming Schedules and Harvesting Techniques
Seaweed farming in Europe is growing and may provide environmental benefits, including habitat provisioning, coastal protection, and bioremediation. Habitat provisioning by seaweed farms remains largely unquantified, with previous research focused primarily on the detrimental effects of epibionts, rather than their roles in ecological functioning and ecosystem service provision. We monitored the development and diversity of epibiont assemblages on cultivated sugar kelp (Saccharina latissima) at a farm in Cornwall, southwest UK, and compared the effects of different harvesting techniques on epibiont assemblage structure. Increases in epibiont abundance (PERMANOVA, F4,25 = 100.56, p < 0.001) and diversity (PERMANOVA, F4,25 = 27.25, p < 0.001) were found on cultivated kelps over and beyond the growing season, reaching an average abundance of >6000 individuals per kelp plant with a taxonomic richness of ~9 phyla per kelp by late summer (August). Assemblages were dominated by crustaceans (mainly amphipods), molluscs (principally bivalves) and bryozoans, which provide important ecological roles, despite reducing crop quality. Partial harvesting techniques maintained, or increased, epibiont abundance and diversity beyond the farming season; however, these kelp plants were significantly fouled and would not be commercially viable in most markets. This paper improves understanding of epibiont assemblage development at European kelp farms, which can inform sustainable, ecosystem-based approaches to aquaculture.

Home sweet home: Comparison of epibiont assemblages associated with cultivated and wild sugar kelp (Saccharina latissima), co-cultivated blue mussels (Mytilus edulis) and farm infrastructure
AbstractSeaweed farming is expanding in Europe and may provide environmental benefits similar to those from natural kelp forests and shellfish farms, including habitat provisioning. Few studies have substantiated these claims however, and it remains uncertain whether seaweed farms will support similar biodiversity to kelp forests or provide valuable long-term habitat beyond the harvest season. We repeatedly surveyed an integrated sugar kelp (Saccharina latissima) and blue mussel (Mytilus edulis) farm in southwest UK to compare epibiont assemblages between cultivated kelps, to those from three nearby wild kelp populations, and to epibionts on farmed mussel lines and unseeded ‘bare’ lines. We found farmed kelps supported over 217 times the abundance of epibionts living on wild kelps at harvest time, however, taxonomic diversity per kelp was lower at the farm. Farmed kelp assemblages were dominated by amphipods, which were present on the wild kelps but in much lower numbers. Farmed kelp also supported distinct assemblages to cultivated mussels, which were similarly dominated by amphipods, but hosted higher relative abundances of crabs, echinoderms, worms and red algal biomass. The bare lines were heavily colonised by another pseudo-kelp, Saccorhiza polyschides, which supported similar epibiont assemblages to the seeded S. latissima lines. Our findings indicate that cultivating bivalves alongside seaweed can increase habitat provisioning at a seaweed farm and extend its permanence beyond typical seaweed cultivation periods as bivalves have longer, continuous farming periods. However, the presence of mussels will likely influence the epibiont assemblages on the farmed kelp, which are distinct from wild kelp populations.
