Oceanographic and ecological interactions with an offshore, long-line mussel farm

University of Plymouth supervisory team 

Globally, the development of offshore aquaculture has the potential to provide the most sustainable source of protein to feed our growing population. In 2013, the University of Plymouth commenced a robust annual monitoring study of the UK’s 1st large scale offshore mussel farm in Lyme Bay, south west UK. To date, the study has been valuable in demonstrating the interactions of the farm with the surrounding ecosystem, showing the potential to increase habitat value for the benthos and mobile commercially valuable species. This project will build on the annual monitoring with a particular focus on the oceanography and plankton.

The PhD student will be expected to undertake fieldwork using a range of fishing vessels and sometimes in challenging conditions. Therefore, experience of working at sea is essential. In addition to monitoring oceanographic variables such as temperature, salinity, oxygen, chlorophyll, cDOM, plankton will be seasonally collected and analysed with the support of the Continuous Plankton Recorder survey at the Marine Biological Association. Annual benthic impact surveys will adopt methods already developed at the farm including ROV, towed, baited, and midwater video and grabs. Potential topics for investigation will include:  

  • Effects of the mussel farm on oceanography and ecosystem processes and services
  • Functional change of benthic and commercially targeted species
  • Diversity of rope biodiversity and associated Fish Aggregation Device effects.


The studentship will have four year duration and will cover full-time home/EU tuition fees plus a stipend of £14,777 per annum. The position is open to UK and EU citizens with appropriate qualifications who have been resident in the UK for three years. EU citizens who have not been resident in the UK for three years may qualify for a fees only scholarship.


Applicants should be highly motivated, have strong personal and communication skills and have a relevant undergraduate degree at 2:1 or above, and ideally an appropriate MSc or MRes qualification. An oceanography and marine fieldwork background is essential. Previous experience in plankton ID, video, statistical and GIS analysis would be beneficial.
