The focus of my research is on growth and survival mechanisms in the early life of fishes. The research is experimentally oriented, and covers aspects of marine juvenile production and process oriented recruitment studies. Recently I have focused on experimental studies on herring from different populations and their adaptations to native environments. 

Size-selective mortality in cultured fish is often due to aggression and cannibalism. A large effort has been made to elucidate factors promoting cannibalism in captive cod (e.g. hunger level, size, size differences etc.). Size- and temperature dependent growth in juvenile flatfish and cod has also been studied with the aim of determining the growth potential under culture conditions. The growth process is very dynamic during the early life stages, and controlled laboratory experiments are carried out to calibrate methods used for growth characterization (e.g. RNA:DNA analysis, otolith microstructure analysis, fatty acid analysis).

The age of field caught fish larvae is often difficult to assess. Fortunately, growth increments are usually formed on a daily basis in the ear stones (otoliths) of fish larvae. It is thus possible to estimate the larval age in days in a similar manner as one determines the age of older fish by counting yearly zones in the otoliths and scales. The growth pattern in the otolith also reflects the previous growth history of the larva, and can be used to determine where, and under what conditions, the larva grew up. The otolith has therefore often been referred to as the "black box" in fish. An important part of the ageing research is related to the accuracy and precision of the age estimation. Knowledge in this field is of great importance in process studies and fisheries management.
