Geoff has worked on numerous national and international fisheries, including orange roughy, Patagonian toothfish, southern bluefin tuna and blue grenadier. He also has an international reputation for his work on understanding and minimising the impacts of the incidental capture of albatrosses and petrels in industrial oceanic fishing.
