Food selection and digestion characteristics of Atlantic halibut ( Hippoglossus hippoglossus) larvae fed cultivated prey organisms

The aim of the present study was to investigate the pattern of food selection by larvae of Atlantic halibut fed Brachionus plicatilis and different size classes of Artemia franciscana, including short-term enriched (ST) A. franciscana nauplii. A second aim was to study the digestibility of different...

Zusammenfassung:The aim of the present study was to investigate the pattern of food selection by larvae of Atlantic halibut fed Brachionus plicatilis and different size classes of Artemia franciscana, including short-term enriched (ST) A. franciscana nauplii. A second aim was to study the digestibility of different size classes of A. franciscana by halibut larvae. The larvae did not show any significant preference for B. plicatilis or nauplii of A. franciscana during the first 2 days after initiating first feeding at 285 day degrees. From day 3 and onwards, they selected significantly ( P
