Initial feeding rates of Atlantic halibut larvae (Hippoglossus hippoglossus) at different prey densities

Abstract

At the end of yolksac stage (36 days after hatching) halibut larvae were offered the prey organism Artemia salina at different densities ranging from 1 to 100.000 litre ^- 1. The feeding experiment was carried out in 11 black plastic tanks (10 litre) each containing 20 larvae. The optimal prey concentration in the initial first feeding situation was found to be in the range of 700 - 7.000 Artemia litre^- 1.
