Fig. 3. Correlation between the number of movements (per hour) and oxygen
consumption (µmol min1 g1 embryonic
body dry mass) in chorionated (open circles, chorion intact), dechorionated
(closed circles, chorion removed), and hatched (triangles) rainbow trout
embryos around the time of hatch (3 days before hatch to 3 days after hatch).
Embryos were dechorionated 3 days before hatching. Movements were measured
while the embryos were in the respirometers.
