Adjunct Professor Albert K. Imsland (May 2010, ISI statistic 96, H-index 21) has long-term research experience in fish growth and development, reproduction and adaptation to the environment with special focus on cold-water marine species. Central in Imsland‘s research is the internal and external factors that control the growth and maturation process in fish, including how these are controlled by the genetic background of the fish and/or controlled by environmental factors. Imsland also works as research director in aquaculture in the Tromsø based Akvaplan-niva AS were the aim is to make scientific findings and knowledge in aquaculture applicable in real “daily life” situations at the fish farm
