Effect of malachite green on the hatching of Ivory shell (Babylonia areolata) eggs

Abstract

Abstract

The purpose of the present study was to assess the toxicity of malachite green on hatching percentage of Babylonia areolata. The experimental treatments consisted of eggs of Babylonia areolata soaked in various concentrations of malachite green (0.1, 0.5, 1.0 and 5.0 mg/mL) and
a control (eggs not soaked in malachite green). Babylonia areolata eggs were incubated for 7 days and hatching percentage was calculated. Results showed that Babylonia areolata eggs in the control treatment displayed the highest percentage of hatching (93.27 ?? 6.36%). Soaking in malachite green, resulted in a low hatching percentage. In addition, Babylonia areolata eggs in treatment with
5.0 mg/mL malachite green resulted in the lowest percentage of hatching with a significant difference (P<0.05) from other treatments. This study concluded that 5 mg/mL malachite green is toxic to Babylonia areolata eggs resulting in significantly reducing hatching percentage.
