Effect of season, sex and reproduction on zinc concentration in the soft tissues of Meretrix casta (Chemnitz) (Mollusca: Bivalvia) collected from Vellar Estuary, Porto Novo, India

Effect of season, sex and reproduction on zinc concentration in the soft tissues of Meretrix casta (Chemnitz) (Mollusca: Bivalvia) collected from Vellar Estuary, Porto Novo, India

The investigation was undertaken to determine the impact of ecological and biological factors on the bio-accumulation of zinc in Meretrix casta collected from Vellar Estuary. The concentration of zinc in water, sediment, whole animal tissues and different soft body parts, such as adductor muscle, fo...

The concentration of zinc in water, sediment, whole animal tissues and different soft body parts, such as adductor muscle, foot, mantle, gill, gonad and digestive diverticula of both male and female, were analysed separately. A high concentration of zinc was discernible during the monsoon, whereas it was low during summer. The metal concentration in the sediment was higher than in the water and body tissues. Among the body tissues, gill tissues showed high values followed by the mantle, digestive diverticula, gonad, foot and adductor muscle. A statistical analysis revealed a significant positive correlation between zinc concentration in body tissues and ambient medium. A significant negative relationship was encountered between salinity and zinc concentration in animal body tissues. El presente trabajo se llevó a cabo para determinar el impacto de factores ecológicos y biológicos sobre la bioacumulación de zinc en Meretrix casta del estuario de Vellar. La concentración de zinc en el agua, sedimento, tejidos íntegros y diferentes partes blandas, tales como el músculo aductor, pie, manto, branquia, gónada y divertículos digestivos tanto de machos como de hembras, se analizaron por separado. Se detectó una alta concentración de zinc durante el monzón, mientras que la concentración fue baja durante el verano. La concentración de metales en el sedimento fue mayor que en el agua y en los tejidos corporales. Entre los tejidos corporales, los tejidos branquiales mostraron valores altos seguidos por el manto, divertículos digestivos, gónada, pie y músculo aductor. Un análisis estadístico mostró una correlación positiva significativa entre la concentración de zinc en los tejidos corporales y el medio ambiente. Se encontró una relación negativa significativa entre la salinidad y la concentración de zinc en los tejidos corporales.
