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.
