Concentration of Trace Metals, Intersexuality and Histological Alterations of Ruditapes philippinarum from Gamak Bay in Korea

Abstract

This study investigated concentration of trace metals, intersexuality and histopathology of digestive gland in Ruditapes philippinarum. Samples were collected from three areas of Gamak Bay in May, 2010. The concentration of trace metals showed that Al was highest, Zn was second high concentration and the lowest concentration was Cd. The intersexuality was 18.5% and female was higher than the male. Intersex type was observed one type. Destruction of digestive tubule epithelium was highest among other biomarkers in digestive gland. Distribution of basophilic cell was 5.8% and lipofuscin was 1.8%.

In addition, harmful bacteria or viruses can easily accumulate in their tissues because of their need for substrate attachment, where they thrive via filter-feeding (Jeon et al, 2015).…”
