Fig. 10. Solute concentrations (mmol kg^–1 H₂O) in the hydrating oocytes of Atlantic halibut as calculated from solute contents (nmol oocyte^–1, Figs 6, 9) and water content (mg oocyte^–1, from Fig. 4) as a function of oocyte and egg wet mass. The curves are polynomials. Data for NH₄⁺ ions refer to the present oocyte material, as published in Terjesen et al. (2001). solutes, sum of measured solutes; FAA, free amino acids.
