Resumen

This is the first published report on morphological and osteological malformations in hatchery produced Sahyadria denisonii. Morphological abnormalities were photographed with a digital camera and digital X-ray. In present study, out of 950 larvae produced only 12 individuals (1.26%) were found to have any type of abnormality, including lordosis, scoliosis, kyphosis, semi-operculum, fin deformity, mouth deformity, head deformity and multiple type deformities. The exact cause of abnormalities could not be definitively determined, but the possible aetiologies are discussed. The present record is, nevertheless, significant owing to the occurrence of deformity in hatchery produced young ones of a freshwater ornamental fish for which induced breeding is considered to be the key to conservation
