    Abstract

    The Indian mackerel Rastrelliger kanagurta is known to be dioecious with male and female gonads in separate individuals. However, gonadal abnormalities such as hermaphroditism and other aberrations have been observed in a few instances. Gonadal abnormalities in mackerel observed during regular biological sampling from fish samples collected from the landing centre is reported here. For the histological analysis, the gonads were fixed in 10% neutral buffered formalin, dehydrated in ethanol series and the cleared samples were embedded in paraffin wax and made into blocks.
