Description 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.
