PhD Studentship – Marine Sciences: Benefits and Impacts of Use of Light in UK Fisheries and their Wider Effect on the Marine Environment

The University of Plymouth invites applications for a 3.5-year fully funded PhD studentship within its renowned Marine Institute, starting 1st October 2026. This project investigates the use of light in UK fisheries, particularly its benefits and impacts on the marine environment, with a focus on innovative methods such as the Fishtek Marine scallop pot. This world-first technology uses lights inside adapted crab and lobster pots to attract king scallops, potentially offering a more sustainable alternative to traditional dredging methods. The research will address key questions about how lights attract scallops, the effects on scallop stocks and other marine species, and the broader ecosystem implications.

The successful candidate will employ a combination of data analysis, aquarium and field-based experiments, and population modelling to explore:

• Cascade effects of pot lights on scallops and other marine species using remote cameras
• Effects of lights on scallop movement using tagging in relation to density and environmental conditions
• Effects of lights on scallop reproduction and population dynamics

Through this research, the student will develop advanced skills in data analysis, experimental design, and population modelling, as well as gain hands-on experience working on research and fishing vessels. Professional development opportunities include presenting at national and international conferences, media training, and co-authoring publications. This training will prepare graduates for careers in academia, environmental consultancy, conservation, and resource management.

Supervision Team: Dr Bryce Stewart (Lead Supervisor), Dr Thomas Davies, Professor Tim Smyth, Dr Rob Enever, Dr Harry Thatcher, and Mr Tom Hooper (Fishtek Marine).

Funding: The studentship covers Home or International tuition fees and provides a stipend of £20,780 per annum (2025-26 rate; 2026-27 rate TBC) for 3.5 years. The final 6 months of the four-year registration period are self-funded for writing-up.

Eligibility: Applicants should hold a first or upper second class honours degree in a relevant subject or a Masters qualification. Strong analytical skills and an interest in biodiversity, fisheries, and conservation are essential. Willingness to participate in boat-based fieldwork is required; a SCUBA diving qualification is desirable but not essential.

Application Process: Apply via the University of Plymouth studentships page by 12 noon on 2nd February 2026. For informal enquiries, contact Dr Bryce Stewart.
