Halibut (Hippoglossus hippoglossus L.) yolk sac larvae were raised in incubators with
different rates of continuous flow. Most larvae died between Days 10 and 29 after
hatching. Rate of mortality increased with increasing rate of flow, but in a stagnant
incubator there were no surviving larvae beyond Day 12 after hatching. Larval dry
weight decreased with increasing rate of flow, whereas yolk sac dry weight did not
differ significantly. Yolk sac utilization efficiency was higher with lower flow.
