Abstract

The occurrence of hermaphroditism in the small-mouthed thrcadfin fish,
Polynemus microstoma Bleeker, collected from the Palk Bay and the Gulf of
Mannar is reported for the first time. Hermaphroditism is found in both the
lobes of the gonad. The two sex portions in the ovotestis, which are easily distinguishable
by their colpur, adhere along the entire length of the gonad in
antero-posterior direction. The testicular portion is on the inner lateral side of
the gonad. The relative size of the male and female portions of the ovotestis
varies in different specimens. It is seen from the microsections that the two sex
portions are separated by a thin connective tissue.
