Halibut eggs were hatched in total darkness and in illumination
(60 lux light). A simoultanous hatching to a final hatching of
99%, and positive buoyant larvae in the dark hatching jars were
experienced. In the illuminated group the hatching was postponed,
hatching curve progressed: more slowly to a final hatching of 72
and 80% in two experiments. Both eggs and larvae developed a
slightly negative buoyancy.
