Dr Charlie Ellis – Postdoctoral Research Assisstant
Charlie is a biologist passionate about marine and fisheries conservation. Having grown up in coastal North Cornwall, a fascination for marine life became interest in creating sustainable ways to meet seafood demand, and the conservation of both traditional inshore fishing fleets and the marine ecosystems they operate in, which naturally led him into collaboration with the National Lobster Hatchery from 2005.
Having held several roles at the Hatchery following his graduation from Plymouth University, Charlie undertook a PhD with the University of Exeter in 2012, focussing on the molecular, reproductive and population ecology of European lobsters, and the implications the species biology has on their conservation, especially via hatchery stock enhancement. This project has helped lay the groundwork to use genetic markers to test population structure and reproductive ecology in local lobsters, and provide lobster hatcheries and alternative stock conservation measures with a genetic method to identify released animals, enabling assessments of how well they contribute to the sustainability of pressured or depleted marine populations.
After receiving his doctorate in 2016, Charlie re-joined the NLH team to work on Lobster Grower 2 (LG2), our collaborative mariculture research project which has significant scope to revolutionise the productivity and sustainability of lobster fisheries and seafood supply. Charlie is responsible for designing, sampling, analysing and reporting on biological and oceanographic factors and their compatibility with the successful mariculture of European lobsters. Charlie also helps supervise collaborative research students and assists in the development of the strategy and capacity for NLH research.
