Abstract

Seventeen adult anomalous specimens of Cirrhinus mrigala (Ham.-Buch.)were seen among fish collections from freshwater fish ponds of Kathua district and have been elaborated. Morphological deformities observed are truncated body with dorsal protuberance (twelve specimens), post dorsal truncated body with a depression on left side (one specimen), curved trunk (one specimen), injured truncated caudal peduncle (two specimens) and highly truncated deflexed caudal peduncle and aberrant anal and caudal fin (one specimen). Radiological study has revealed various vertebral anomalies viz. lordosis, kyphosis, scoliosis, ankylosis, trough, vertebral overlapping and duplication. Multiple factors known to induce anomalies in fishes have also been described.
