Judith Brown

Research Interests

Ageing and reproductive biology of Patagonian toothfish; tagging of toothfish using archival pop-up tags

Background and Qualifications

After graduating in Applied Marine Biology at Heriot-Watt University, Edinburgh, Judith worked as a research scientist at Inveresk Research carrying out ecotoxicology studies on various aquatic species. She then worked for the British Antarctic Survey at two of their research stations. Firstly she spent two years at the applied fisheries laboratory at King Edward Point, South Georgia conducting research on the commercially exploited species of this area (work included ageing of fish and squid, diet analysis, dissection, taxonomy, histology, trammel netting, pot fishing, plankton trawling and CTD drops). She also helped build and run the temperature controlled facility. She then spent six months at Signy Island research station implementing the long-term limnology programme. After working for BAS she spent 2 ½ years working for the Eden Rivers Trust monitoring the salmonid population in the River Eden and helping execute restoration projects.

Her current role at FIFD is ageing and age validation of Patagonian toothfish, Dissostichus eleginoides in Falkland waters. She will also be working on their reproductive biology and tracking toothfish movements with archival tags.
