Jawad et al., 2014, Incidence of Lordosis in the Cyprinid Fish, Carasobarbus luteus and the Shad, Tenualosa ilisha Collected from Barash Waters, Iraq, International Journal of Marine Science, Vol.4, No.45 1-5 (doi: 10.5376/ijms.2014.04.0045)

Incidences of severe lordosis involving two flexions are reported in a specimen of cyprinid fish Carasobarbus luteus and Tenualosa ilisha. For both species, the values for the angles lies between the lines passing through the sides of the vertebral column and enclosing the curvature and the depth of the curvature of the angle were obtained. Also, the ratio of the vertebral column to the fish total length of the deformed and the normal specimens of the two species were calculated. Possible causes for such anomalies were discussed.
