Dr Chris Barrett

Lead Shellfish Advisor

Dr Barrett's current interests are around cephalopod fisheries research to better understand squid and cuttlefish population dynamics, to try and ascertain the status of their stocks. He also provides external advice on the impacts of anthropogenic developments on shellfish around England and Wales.

My PhD focussed on intertidal fish communities and identifying the mechanisms for interspecific and intraspecific coexistence, through studies of their spatiotemporal population dynamics, diet, degrees of co-occurrence, habitat predictors, ecomorphology, diel activities and behaviour. I then joined Cefas as a Fisheries Scientist in the Applied Fisheries Science and Technology Group, where I developed a good understanding of how commercial fisheries operate and how fisheries have to adapt in response to the Common Fisheries Policy’s reform and its associated discard ban for quota species. I later joined the Shellfish Team as its Team Leader and had an active role in liaising with shellfishers and teaching them how to use novel technology such as Bluetooth callipers to self-sample, to help fill knowledge gaps in stock assessments. I also began building a specialism in cephalopod fisheries as it became apparent that commercially important, valuable squids and cuttlefish fisheries currently have no management in place.

I am Cefas’ representative to the IFCA TAG (Technical Advisory Group) and am in close contact with their staff to standardise our practises and help re-enforce one another’s evidence bases to ensure policy decisions are made based on strong, robust data. More recently, I have been involved in the ‘What Works in Conservation?’ project for marine fish; the first project of its kind to amalgamate evidence of conservation interventions for marine fish, to help inform managers and decision makers as to what does or doesn’t work in protecting various marine fish around the world. Further to being Cefas’ lead advisor to the MMO and NRW on the impacts of offshore developments on shellfish, I am now also building expertise in providing dredge and aggregate, and finfish advice.
