Abstract：
:The mortality of roach (Rutilus rutilus) embryos increased during the early embryonic phase following exposure to Al and acidity from pH 6.7 to 5.0. No roach hatched at pH<5.00 or at pH 5.00 in the presence of Al. By contrast, increased embryonic mortality in pike (Esox lucius) occurred mainly during and after the normal hatching period due to the acidity-dependent prolongation and inhibition of hatching at pH 4.00. Newly hatched fry of both species were more sensitive to Al than the embryos. A reduction in the development of yolk-sac fry occurred in pike at pH 4.00 and in roach at pH 5.00, and in the presence of Al at pH< or =5.00 and pH< or =5.75, respectively. Thus, the most susceptible early developmental phase to acidity differed between the acid-sensitive roach and the acid-tolerant pike, although the newly hatched fry was the developmental phase most sensitive to Al for both species.
