Malformaciones morfológicas y oseas en ejemplares de criadero de barbo de línea roja, Sahyadria denisonii (Day 1865) (Cyprinidae)Se publican, por primera vez, malformaciones morfológicas y osteológicos de Sahyadria denisonii producidas en criadero. Se fotografiaron anomalías morfológicas con cámara digital y de rayos X digital. De 950 larvas producidas, sólo 12 individuos (1,26 %) presentaron algún tipo de anomalía, incluyendo lordosis, escoliosis, cifosis, semi-opérculo, deformidad de la aleta, deformidad de la boca, deformación de la cabeza y deformidades múltiples. La causa exacta de anomalías no se pudo determinar, pero se discuten las posibles etiologías. Sin embargo, el registro actual es significativo debido a la aparición de deformidades en peces ornamentales de agua dulce de criadero, para los que se considera la reproducción inducida como la clave de su conservación.Palabras clave: Deformidad, Reproducción inducida, Radiografía, Ghats Occidentales. AbstractThis 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.
Se registró una deformidad vertebral en un ejemplar silvestre de Puntius denisonii de los Ghats occidentales, India. El estudio radiológico y morfológico comparativo de un pez normal y el deforme revelaron una malformación vertebral en la zona caudal de la aleta dorsal. Se discuten las posibles causas de la deformidad vertebral.
