Abstract :In this study, the length-weight relationship insert ignore into journalissuearticles values(LWR); and condition factor insert ignore into journalissuearticles values(CF); of Mesopotamian spiny eel Mastacembelus simack insert ignore into journalissuearticles values(Banks & Solander, 1794); caught from the Tigris River and Murat River basins between 2014 and 2016 were investigated. While the length of the fishes ranged between 24.00 and 67.40 cm for Tigris basin and 27.20 and 60.50 cm Murat basin, the weights changed between 31.70 and 585.30 g for Tigris basin and 38.20 and 385.00 g for Murat basin. It was determined positive allometric growth in individuals with a length of between 27.20 and 31.80 cm insert ignore into journalissuearticles values(b=3.54); in Murat Basin, 41.20 and 52.80 cm insert ignore into journalissuearticles values(b=3.27);, and 53.70 and 67.40 cm insert ignore into journalissuearticles values(b=4.77); in Tigris Basin, while negative allometric growth insert ignore into journalissuearticles values(b<3); was determined in total all samples of both basins. The length-weight relationship was found as W=0.005L2.73 insert ignore into journalissuearticles values(R2=0.94); for Tigris and W=0.005L2.75 insert ignore into journalissuearticles values(R2=0.97); for Murat rivers. Average CF has the same value insert ignore into journalissuearticles values(CF=19); for Tigris and Murat rivers basin fish.
