- Abstract
Abstract An intensive method of Juvenile Atlantic halibut, Hippoglossus hippoglossus (L.), production has been under development over the last decade because of the problems associated with the extensive method. The lack of initiation of feeding behavior has been the main obstacle for successful indoor rearing under artificial light and feeding conditions, In the present paper, an intensive method for the first feeding of halibut larvae is described and verified by practical feeding trials. The method involves circular 1.5-m3 indoor tanks with aperipheral ringshaped cover, the use of continous light, UV-A radiation during the first 24h, central up-welling of water made byh aeration and the use of microalgae in the rearing water. The single most important factor in sch system is to maintain a current pattern which allows the larvae to orientate and position themselves to face the water current for easy capture of prey.
