Occurrence of abnormally developed gonads in fish is rather more uncommon in freshwater fish than marine
fish. It is therefore worthwhile to disseminate the information of occurrence of a single-lobed ovary in Cirrhinus
mrigala brood fish as an abnormal phenomenon. During April 2011 to March 2013, around 500 brood fish samples
of Indian major carps (Labeo rohita, Catla catla and C. mrigala) were collected from different government and
private fish farms of Assam and Tripura located in the Northeast of India. Among them, one C. mrigala specimen
measuring 41 cm in total length and 640 g in weight collected from Ulubari fish seed farm of Guwahati, Assam
during June, 2012 was found to have a single-lobed ovary instead of the normal bilobed structure. The ovary occupied the
entire body cavity and the majority of ova were round and translucent. The ovary contributed substantially to the total
body weight with gonado-somatic index of 32.81 which was the highest among all the mrigal specimens examined. The
study indicates possibility of artificially inducing development of single-lobed ovary in C. mrigala for achieving possible
higher spawn outputs in induced breeding of the cultivable species.
