Description IN the course of the examination of more than 2300 gonads of Katsuwonus pelamis
(Linnaeus) for the study of the spawning habits of this fish, from the Laccadive
Sea at Minicoy, I came across three abnormal gonads including a hermaphrodite
one. As this is the first record of abnormal gonads of tuna from Indian waters
it has been described in this present note.
The normal gonads of the skipjack (Fig. 1) are paired and elongate organs with
the left lobe usually being shghtly larger than the right and both are suspended from
the dorsal wall of the body cavity by a fold of the peritoneum. They are free distally
but proximally they unite to form a common duct opening into the cloaca.
In the female the posterior part of the ovary itself functions as the duct whereas in
the male there is a slender duct running along the entire length of the mid-ventral
side of each testis.
