“…Moreover, since the collection site was heavily infested with aquatic weed; extreme fluctuation in dissolved oxygen and carbon dioxide content is possible. This may be another factor responsible for occurrence of such abnormality which is well supported by the findings of Anon (1996) and Martens et al (2006). Fowler (1970) and Barlow (1961) reviewed that lower count of some meristic characters in fishes may be due to environmental differences.…”

“…Morphological anomalies in fishes can be attributed to various factors like nutritional deficiency (Cahu et al, 2003), temperature variations (Gluth and Hanke, 1983), low dissolved oxygen (Turner and Farley, 1971;Anon, 1996), high carbon dioxide concentration in water (Martens et al, 2006), pollutants like chlorinated hydrocarbons, organophosphates, pesticides, heavy metals (Weis and Weis, 1989;Lin Sun et al, 2009), parasitic infection (Cunningham et al, 2005), developmental error and injury (Devadoss, 1983;Dutta and Kumar, 1991;Gupta et al, 2000 andSubba, 2008). Anopthalmia (the congenital absence of one or both eyes) in fish have been reported by many authors.…”

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.

“…Concomitant with this, CO 2 concentrations have increased reaching levels up to 40 mg/L (Martens et al, 2006). Peak density in the systems typically occurs just prior to transfer to sea with the risk of critical CO 2 levels reducing initial growth in sea cages.…”

Record of an Abnormal Schizothoraichthys esocinus (Heckel) from the Himalayan River Chenab Draining Jammu Region of the J&K State, India

Two deformed Specimens of Schizothoraichthys esocinus were observed among the fish collections from the river Chenab and is the first record for any Himalayan stream. One specimen was recognised by its flat caudal fin base and widely spaced caudal fin lobes. The other showed the post dorsal truncated body with a trough, ventral anal bulge and dome in the caudal peduncle region. X-ray analysis revealed hook shaped vertebral column and aberrations in the various vertebrae and caudal fin bones. Possible cause of aberrations in torrential non polluted river is mechanical injury induced by currents during embryonic development.
