Abstract

Copper concentrations in different tissues such as exoskeleton, muscle, gonad, hepatopancreas and gills of Indian white shrimp, Fenneropenaeus indicus females were examined at different stages of gonadal maturation. Adult shrimp (average weight 36 ± 2 g) from wild F.indicus were collected and identified according to their stages by visual examination. The shrimps were immediately sacrificed and dissected in cold (4°C) and individual organs were stored in the freezer for further analysis. Copper concentration was examined in all the organs by atomic absorption spectrophotometer (AAS) and the result showed an increase in copper concentration during ovarian maturation. Amongst the organs examined, gills had highest copper concentration followed by hepatopancreas and ovary and least in exoskeleton and muscle. Copper concentration increased significantly (p<0.01) in all the organs during gonadal maturation and was highest at IV stage of the ovary.
