The University of Plymouth invites applications for a 3.5-year PhD studentship in Marine Sciences, focusing on the benefits and impacts of using light in UK fisheries and their wider effect on the marine environment. This opportunity is part of the Marine Institute, renowned for its century-long leadership in global marine research and home to the largest concentration of marine researchers in the UK. The studentship is fully funded for Home or International students, covering tuition fees and providing a generous stipend of £20,780 per annum (2025-26 rate; 2026-27 rate to be confirmed). The final six months of the four-year registration period are self-funded for writing-up.

The project investigates the innovative use of lights in marine fisheries, particularly the development of the scallop pot by Fishtek Marine, which uses lights inside adapted crab and lobster pots to attract king scallops (Pecten maximus) in commercial quantities. This method is considered to have a significantly lower environmental impact compared to traditional dredging and has garnered international interest. Despite its promise, the ecological effects of light-based fishing methods on scallop stocks, other marine species, and the broader ecosystem remain largely unexplored.

Research topics include:

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

The successful candidate will develop expertise in data analysis, experimental design (both aquarium and field-based), and population modelling. Professional development opportunities include working on research and fishing vessels, presenting at national and international conferences, media training, and co-authoring publications. This comprehensive training prepares graduates for careers in academia, environmental consultancy, conservation, and resource management.

Eligibility requirements include a first or upper second class honours degree in a relevant subject or a Masters qualification, strong analytical skills, and a keen interest in biodiversity, fisheries, and conservation. Willingness to participate in boat-based fieldwork is essential, and a SCUBA diving qualification is desirable but not mandatory.

Applications are open until 12 noon on Monday, 2nd February 2026. For informal discussions about the project, prospective candidates may contact Dr Bryce Stewart. To apply, visit the University of Plymouth's research studentships page and follow the application instructions.
