The effect of carbendazim on embryonic Prussian carp (Carassius gibelio) development and hatching

The aim of the study was to investigate the effect of different concentrations of carbendazim, a commonly used fungicide, on the embryonic development and hatching of Prussian carp, Carassius gibelio (Bloch). The egg samples were incubated with different concentrations of carbendazim - 0.001, 0.006, 0.036, 0.216, and 1.296 mg l^-1, for 98 hours. The results of the data showed that carbendazim at concentrations of 0.036 mg l^-1 and higher were lethal for Prussian carp embryos. There were no significant differences in the hatching rate, percentage of hatched larvae, or in the percentage of deformed larvae exposed to the two lowest concentrations of carbendazim tested (0.001 and 0.006 mg l^-1).The results of the present study showed that carbendazim is harmful to Prussian carp embryos at concentrations of 0.036 mg l^-1 and higher.
