Halibut larvae were exposed to physical stress in the form of different levels of airation. Survival rate, development, dry weight, RNA, DNA and protein were measured. At the end of the experiment the larvae exposed to gentle airation had the highest survival rate, total dry weight, dry weight of the yolk sac, content of RNA and RNA-DNA ratio. However, the group without airation had the highest dry weight of larval body, growth rate and yolk conversion efficiency. The functional jaw development had the same value and were highest in these two groups.
