Applications are invited for a BBSRC fully-funded three year PhD to commence in February 2025.

The PhD will be based in the Faculty of Science and Health and will be supervised by ,  and Dr Ross Brown (University of Exeter). 

Successful applicants will receive a bursary to cover tuition fees for three years and a stipend in line with the UKRI rate, £19,237 for 2024/25. Bursary recipients will also receive a £1,500 p.a. for project costs/consumables. 

Costs for student visa and immigration health surcharge are not covered by this bursary. For further guidance and advice visit our international and EU students ‘Visa FAQs’ page.

This exciting and innovative project aims to address climate change impacts and improve coastal ecosystem services using an Integrated Multi-Trophic Aquaculture (IMTA) approach using kelp and mussels. In industry, there are pressing needs to investigate new systems of ingredient and material production that sit more naturally with a net zero future, alongside efforts to make our current systems more sustainable. Research is needed towards sourcing of nutrient dense, low carbon, land-free diverse ingredients that can be produced using approaches compatible with Net Zero. There is an opportunity to increase ingredients sustainably farmed from regenerative ocean-sources and reduce the pressure on land for nutritious protein products. There is also the possibility to increase impact on enhancing biodiversity and improving water quality.

This IMTA project will be essential for trialing climate change mitigation, understanding kelp-derived blue-carbon biomass and productivity, bioremediation, biodiversity uplift, and maintaining the structure and function of temperate coastal ecosystems, to align with .

Expected deliverables from the four-year program:
 

Yr 1 -3: with support from academia, and industry you will be expected to assess the natural capital services from a low-trophic aquaculture (LTA) demonstrator. Assessments will focus on monitoring three key metrics - biodiversity (e.g., trophic complexity, nursery function and community evenness), nutrient mitigation and carbon sequestration.  To obtain baseline information, a before-after-control-impact (BACI) study will be conducted. This will provide spatial and temporal data to determine the benefits of an IMTA facility from a regenerative aquaculture facility.

Yr 4. You will work closely with the partners to use the three years of data to provide a life-cycle analysis (LCA) of the LTA site. You will provide an economic assessment of the monetary value of natural capital services, including a scaling analysis and assessment of marine natural capital regulatory markets and a recommendation of the most promising natural capital services to develop for environmental and economic benefit, and contribution towards Net Zero.

Ocean foods are gaining popularity in restaurants and supermarkets. Consumers are concerned about sourcing from the oceans, both wild-catch and fish farming, so this low-impact and sustainable project provides alternate sources that can stimulate new routes for renovation and innovation, as well as potential links to regenerative sourcing (e.g., seaweed bio-stimulants).
