A histological observation of the ovaries revealed that most non\u2010migrating eels were at the perinucleolus (43%) or oil\u2010droplet (48%) stage, whereas most migrating eels were at the early vitellogenic (36%) or midvitellogenic (61%) stage.

The <jats:italic>fshb<\/jats:italic> messenger (m)RNA levels were lower in perinucleolus and oil\u2010droplet stages and then significantly increased in the early vitellogenic stage.

The E<jats:sub>2<\/jats:sub> levels at the vitellogenic stage were significantly higher than those at the perinucleolus and oil\u2010droplet stages.
