Ïã¸ÛÁùºÏ²Ê¹ÒÅÆ×ÊÁÏ

I gained my MSc in Marine Environmental Protection at Ïã¸ÛÁùºÏ²Ê¹ÒÅÆ×ÊÁÏ in 2008 with a research project on the population genetics of the Caribbean spiny lobster in the western Antilles. I completed my PhD in 2012 which focused on the connectivity and spatial structure of the scallop fishery around the Isle of Man, funded by the Isle of Man Government. The project involved surveys on the research vessel Prince Madog as well as collaboration with stakeholders including fishermen and processors. Work included population genetics of scallops around the Isle of Man and across the wider European range, statistical modelling of environmental and anthropogenic drivers of spatial variation in scallop reproductive status and modelling of the impact of hatchery reared scallop seed on wild populations.

Post-doctoral research at Ïã¸ÛÁùºÏ²Ê¹ÒÅÆ×ÊÁÏ (2012-2015 and 2019- present) has focused on inshore, data poor, shellfish fisheries across Wales, requiring active engagement with the fishing industry for collaborative data collection. All research aims are closely aligned with fisheries management and policy evidence requirements in order to deliver meaningful research to impact sustainable fisheries management. A key framework for our sustainable fisheries research is to provide evidence for the management of key commercial fisheries within the Ecosystem Approach to Fisheries Management (EAFM), ensuring that single species approaches (such as stock assessment and single species reference points) are complemented with wider ecosystem evidence such as appropriate spatial scales, adjacent effects and long term effects.

I have also spent three years working as a fisheries scientist for a consultancy (2016-2019) where I worked on a range of projects including environmental baseline studies for energy developments, intertidal aquaculture developments and coastal realignment schemes. I have worked in collaboration with fishers and statutory conservation agencies to develop fisheries management plans for several order fisheries and to carry out annual stock status surveys on the fishery. I have also modelled the effect of river flow on salmonid up-stream migration including drought scenarios.

I am currently the project manager for the EMFF sustainable fisheries in Wales project. As well as project management I am the lead researcher for the component of the project using our long-standing relationships with the industry to develop innovative technology for maximising high quality, high resolution fishery-dependant data collection. In addition my current research is investigating the reproductive ecology of lobsters and how this can influence stock assessment and fishery management measures.

• ​​​​​​​​​​​​​​​​​​Whelk and other gastropod fisheries are key species in small-scale artisanal and commercially valuable fisheries worldwide. Within the eastern Atlantic, the whelk Buccinum undatum is commercially important however there is minimal management in most countries.

  This inaugural meeting aims to bring together scientists already working on whelk fisheries from across Europe, North America, and the rest of the world to share best practice, spark collaborations, and review recently published work as well as that underway.

  The workshop will focus on:

  - whelk aging techniques, error and use in routine data collection and stock assessment

  - current stock assessment approaches and challenges, and direction of research/travel for whelk stock assessment​

  8 Jul 2024 – 9 Jul 2024

• Ïã¸ÛÁùºÏ²Ê¹ÒÅÆ×ÊÁÏ’s sustainable fisheries team currently carries out research into baseline biology of commercially important species, fisheries science and how these data can be applied to achieve sustainable fisheries management in Wales. This research has potential to create impact through policy change, guidance to fisheries management and change within the fishing industry through providing and disseminating evidence in support of sustainable fishing practices. It is expected that a range of research carried out by the sustainable fisheries team will come together to create a single impact case study concerning the management of shell fisheries in Wales.
