| Abstract | ||
| A study on improving the hatching quality of fairy shrimp < em> (Streptocephalus sp.) cyst hatching was performed. The chemicals used were H2O2at doses of 3, 5, and 7%, as well as NaHCO3 (baking soda) at doses of 10, 15, and 20g, to study the effects of these substances. In a separate experiemnt, the cysts were hatched either with or without aeration after determining the optimal concentrations of H2O2 and NaHCO3 to stimulate cyst hatching. The results showed that H2O2 improved the fairy shrimp cyst hatching rate at a dose of 3% and NaHCO3 could be used at a dose of 20mg/ L since both provided the best results in terms of hatching quality. Moreover, using chemicals to hatch fairy shrimp cysts in non-aeration conditions presents better results compared to using chemicals with aeration. | ||
