Silver rasbora is a fish that lives in freshwater, especially in river waters. However, the presence of silver rasbora fish is currently difficult to find due to environmental pollution. One of them is organophosphate pollution. This research aims to know how the effect of organophosphate pesticides with sublethal doses on embryo development and the hatchability of silver rasbora fish eggs. The research method was an experiment with a Completely Randomized Design as an experimental design. The treatments used were different organophosphate concentrations: 0, 0.5, 1, 1.5, and 2 ppm, each treatment repeated four times. The main parameters were embryo development and hatchability of silver rasbora fish eggs. Statistical analysis using Analysis of Variance and to find out the difference between one treatment and the other treatment is Duncan's Multiple Range Test. The results showed that the treatment of different organophosphate concentrations had a significant effect (P <0.05) on the speed of embryo development and the hatchability of silverfish eggs. The fastest embryo development occurred in treatment two ppm and the slowest at treatment 0 ppm. The highest hatchability of silverfish eggs was found in treatment K (93%) and the lowest in treatment two ppm (19.5%), which was not significantly different from treatment 1.5 ppm (26%).
