Abstract :In this study, DNA damage in hybrid tilapia exposed to the short-transport process has been investigated. Gill samples were taken from tilapia which after immediately from the transport process insert ignore into journalissuearticles values(t0 group);, after 6 hours from transport process insert ignore into journalissuearticles values(t6 group);, after 12 hours from transport process insert ignore into journalissuearticles values(t12 group);, after 24 hours from transport process insert ignore into journalissuearticles values(t24 group); and not applied transport process insert ignore into journalissuearticles values(control group); have been investigated and the results have been compared as statistically. The Damage frequency insert ignore into journalissuearticles values(%);, Arbitrary Unit and Genetic Damage Index insert ignore into journalissuearticles values(%); were evaluated in gill cells of tilapia. As a result of the study, it is determined that highest the damage frequencies insert ignore into journalissuearticles values(%); as 69.00±4.58 and 66.00±3.00 were significantly observed in t0 and t6 groups respectively insert ignore into journalissuearticles values(P<0.001);. Besides, it is observed that the other damage parameters insert ignore into journalissuearticles values(Arbitrary unit and genetic damage ındex); in the gill samples of t0 and t6 groups were significantly higher insert ignore into journalissuearticles values(P<0.001); compared to the control, t12 and t24 groups. The Arbitrary unit and Genetic damage index increased in fish after the transport process insert ignore into journalissuearticles values(especially, t6 and t12); but a significant decrease occurred after 24 h insert ignore into journalissuearticles values(returning to the control levels); insert ignore into journalissuearticles values(P< 0.001);.
