Fig. 4. (A) The dissolved oxygen (DO) concentration
100 µm inside the
chorion in 31 d.p.f. rainbow trout embryos before hatching, and in the same
embryos, the DO concentration in the boundary layer relative to the distance
to the chorion. Values are means ± s.e.m., N=6. (B) The
boundary layer gradient (% sat; to Ch, the difference between the DO in the
free-stream and the DO at the surface of the chorion) compared with the
gradient across the chorion (x Ch, the difference between the DO at the
surface of the chorion and the DO inside the chorion).
