Resumo: | During oogenesis of Solea solea L., gonadal changes in water, Na super(+) and K super(+) ions seem to be related to yolk protein incorporation by the oocyte. The decrease in oocyte water accumulation, associated with an increase in pericellular water accumluation and a decrease in K super(+) concentration occurs when vitellogenin enters the oocyte. Na super(+) concentration decreases in the oocyte at the end of the exogenous vitellogenesis when the first stages of the oocyte maturation take place. Water accumulation in the pericellular space during vitellogenesis allows the rapid transfer of water from this compartment into the oocyte during the terminal phase of maturation. However the total amount of gonadal water remains stable.
