“…Dabrowski et al (1988) and Frischkenecht et al (1994) reported vitamin-C deficiency in the diet also leads to vertebral deformities. Finally, a genetic basis has also been proposed for spinal deformations (Fagbuaro 2009, Arbuatti et al 2013, vertebral deformities are known to be hereditary and non-hereditary (Yamamoto et al 1963). Vertebral abnormalities are also known to occur in Cirrhinus mrigala (Hamilton, 1822) and Hypothalmichthys motitrix (Valenciennes, 1844) (Raj et al 2004) and Poecilia wingei Poeser, Kempkes & Isbrücker, 2005(Arbuatti et al 2013 due to inbreeding depression.…”

“…Fish deformities have been also resulted from nutritional deficiencies, unfavourable abiotic factors, rearing conditions and genetic factors (Yamamoto et al 1963, Tave et al 1982, Dab-rowski et al 1988, Boglione et al 1993, Frischknecht et al 1994, Wang & Tsai 2000, Fagbuaro 2009, Amitabh & Firoz 2010, Arbuatti et al 2013. However, earlier studies reported that the possible aetiologies and mechanisms responsible are not well understood (Koumoundouros et al 1997, Gavaia et al 2002.…”

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.

“…Offspring from cadmium‐exposed females had the highest incidence of abnormalities (15 out of 62, or 24%), followed by offspring from copper‐exposed females (8 out of 56, or 14%), whereas no abnormalities were evident in offspring from control females (0 out of 68, or 0%). The most common abnormalities (18 of the 23 abnormalities, or 78%) that we observed were curvatures in the vertebral column . Scoliosis and lordosis vertebral deformities (8 and 7 cases, respectively) occurred among both the copper and cadmium groups, whereas kyphosis (3 cases) occurred only in offspring from cadmium‐exposed females.…”

The present study assessed the effects of maternal copper or cadmium exposure in a live-bearing fish. After a 10-d exposure to background levels (control) or 0.15 μM copper or cadmium, gravid females were transferred to clean water. Once a female gave birth, the authors analyzed her newborn offspring for lipid peroxidation, elemental composition (copper, cadmium, and calcium), and metal tolerance. The authors raised other offspring until sexual maturity and analyzed their growth rate, incidence of abnormalities, and sex ratio. Their earlier research, using the same species and exposure design, demonstrated that cadmium and copper were transferred from gravid females to their offspring. The present study showed that offspring of copper-exposed females had a reduced size at birth, developmental abnormalities, elevated tissue cadmium levels, and reduced tissue calcium levels. Offspring of cadmium-exposed females had elevated levels of lipid peroxidation, developmental abnormalities, and lower tissue levels of both copper and calcium. No effects were detected with respect to offsprings' growth rate or sex ratio. Offspring of metal-exposed fish had a reduced tolerance to the metal that their female parent had been exposed to, and the tolerance showed an inverse relationship to the tissue metal level in the offspring. The latter indicates that the reduced tolerance was the result of an increased body burden prior to the tolerance quantification. The present study constitutes the first report in live-bearing fishes showing that maternal metal exposure has a wide range of negative impacts on the offspring.

“…Moreover, present case study is the first known application of texture analysis in medical imaging applied to fish species and represents a start point for further studies in aquariology and particularly in aquaculture where spinal deformities occur relative frequently and are cause of economic losses [17,18] .…”
