Histopathological aberration and 17-β-estradiol imbalance in green mussel Perna viridis population cultured in Java Sea, Indonesia

Histological aberration is a common phenomenon in aquatic animals exposed to pollution. Pollution also influences the hormonal condition of an organism, including the green mussel Perna viridis. In the present study, degeneration and lyses were studied in the females' oocytes of P. viridis and the 17-β-Estradiol was measured in the gonads of female and male individuals. The damage analysis was carried out and the aberration level in the tissue was measured by image processing analysis using R-Software. The concentration of 17-β-Estradiol in the gonads was measured by the ELISA method. Histopathological aberration and 17-β-Estradiol concentration in the female gonad tissue of P. viridis were detected in the samples with variable quantities. The high value of 17-β-Estradiol in males cultured in the industrial city of Indonesia indicated that this mussel species experienced hormonal imbalances and represent a threat with regard to food safety.
