Past, present and future of live feed technology in Norway


The progress in live feed technology in Norway has been directly correlated to the development of intensive marine aquaculture industry. At the end of the 80’s, techniques for live feed production were developed, improved and adapted for use in the new Atlantic halibut industry. However, most of the advances were in the nutritional manipulation of rotifers and Artemia. At the beginning and middle of the 90’s, live feed technology was still based on nutritional studies and this gave success especially in Turbot research. In the last part of the 90’s new diets for use in Artemia enrichment greatly improved the quality of the halibut larvae, especially regarding pigmentation. Nevertheless, this achievement was still based on nutritional studies and with relatively poor technological progress in the area of automation and development of new equipment for live feed production. At the beginning of the new century we see a possibility for progress also in live feed technology and production equipment. The great interest in intensive production of cod juveniles in Norway will without doubt force the improvement of the technological aspects of live feed production. Already now new concepts of mass production of rotifers are being developing and it is expected that automation will be required to meet the high expectations of cod production for the next years. This paper deal with the development of live feed technology in Norway based on almost 2 decades of nutritional studies, and recently with a new technological approach.
