Influence of hydrogen peroxide on hatching of nauplii Artemia sp.

Abstract

Nauplii of the brine shrimp Artemia sp. are the optimal starter food for many fish and crustaceans species. For this reason, technologies for their production are being improved, including the activation of cysts. The effect of different concentrations of hydrogen peroxide on hatching process a as activator was studied. Its optimal concentration has been determined; it amounts to 0.2-0.4 ml/l. The reasons for various impacts of hydrogen peroxide on different Artemia cysts are formulated. The dynamic of brine shrimp hatching with and without the activator was studied. It has been established that the addition of a hydrogen peroxide solution as an activator increases the hatching of Artemia nauplii, however, it does not impress on the rapidity of Artemia nauplii release from cysts.
