“…In the 1482 citations of abnormalities catalogued by Dawson (1964Dawson ( , 1966Dawson ( , 1971 and Dawson & Heal (1976) we found only five, all mentioned earlier, describing this particular anomaly. We found three more in our computerized search of Aquatic Sciences & Fisheries Abstracts from 1977 through March, 1992.…”

“…Intersexuality, which occurs frequently in fishes was discussed in detail described as previously (Atz, 1964) and both normal and abnormal specimens (Dawson, 1971). Explained the importance of characterizing intersex condition in aquatic organisms in order to establish baseline prevalence and factors promoting the development of intersex (Bahamonde, Munkittrick, & Martyniuk, 2013).…”

The present study documents the occurrence of an intersex condition in a natural population of mullet Mugil cephalus L. On closure examination of the dissected fish, 11 females and 7 males were recorded. Histological observations through the testes indicated that one of the male fish showed different developmental stages of oocytes in between the seminiferous tubules. Interestingly, the condition reported here did not show any internal bilateral division of the reproductive system into male and female components. But it had shown the occurrence of oocytes and spermatozoa throughout the entire region of the testis of a functional male. The observation of intersex testis or testicular oocytes (TO) is of first report from the east coast of India. The fish being catadromous, this condition may be related to possible accumulation of chemical contaminants in the habitat water.

“…Anopthalmia (the congenital absence of one or both eyes) in fish have been reported by many authors. A compiled bibliography of 1499 papers on fish anomalies was given by Dawson (1964Dawson ( , 1966Dawson ( , 1971 and Dawson and Heal (1976), of which 63 papers described eye abnormalities (Tave and Handwerker, 1998). Since then, many reports have been published on morphological anomalies in fishes (Kruitwagen et al, 2006;Tave et al, 2011;Saha and Saha, 2013).…”

An abnormal case of anopthalmia in a striped catfish Mystus tengara (66.8 mm in standard length) from Assam is reported in this communication. Thirty eight morphological characters of the abnormal specimen were also studied and compared with normal specimens to observe variation in the morpho-meristic traits, if any. In the abnormal specimen, the proportionate height of the dorsal fin (31.1 mm) and nasal barbel length (75.9 mm) was found to be higher compared to that of the normal specimens (21.6 -26.5 mm and 47.9 -72.5 mm, respectively). While the body depth of anus was higher in case of normal specimens (19.1 -29.2 mm) compared to abnormal specimen (14.5 mm). However, no marked variation was observed in meristic characters. This anomaly does not seem to have affected morphological aspects. Factors like weed infestation, pesticide and herbicide application adversely affecting the habitat is believed to be the cause of such deformity. The abnormality does not seem to have affected the overall growth of the fish.
