Dr. Løkkeborg obtained his PhD at the University of Bergen in 1990. He has conducted many behavioural field investigations using underwater camera and telemetry technology to study swimming pattern, activity rhythms and foraging strategies in fishes and crabs. His studies on fish behaviour also include laboratory works and comparative fishing experiments. Dr. Løkkeborg has been involved in numerous fishing-gear related studies including most fishing gears, and he has studied problems such as methods for fish abundance estimation, harvest strategies, selectivity and impacts on the ecosystem.

Ecosystem effects of fishing activities have aroused a growing concern during the last decade, and Dr. Løkkeborg has been working on three aspects of this problem: mitigation measures to reduce bycatch of seabirds in longline fisheries, impacts of trawling on benthic communities and lost fishing gears (ghost fishing). Dr. Løkkeborg has also been working with problems related to interactions between fishing activities and the oil industry, in particular effects of seismic activity on fish behaviour and fisheries. In relation to the introduction of red king crab in the Barents Sea, he has been involved in studies on distribution, stock abundance estimation and mitigation methods to reduce the bycatch of king crab in the gillnet and pot fisheries targeting cod.

Dr. Løkkeborg has published more than 40 peer-review papers based on his scientific research activities. During his two sabbaticals, Dr. Løkkeborg worked as visiting scientist at Hatfield Marine Science Center in Newport (Oregon, USA) and at the Fishing Technology Service (FIIT) of the Fisheries Department of FAO (Rome, Italy). He is member of ASA Standards Working Group on Effects of Sound on Fishes and Sea Turtles, and ICES-FAO Working Group on Fishing Technology and Fish Behaviour. Dr. Løkkeborg has also been a member of three FAO Expert Consultations on interactions between fisheries and seabirds and sea turtles.
