Highlights • We evaluated biochemical and physiological effects in the brain tissues of rainbow trout exposed to linuron. • 8-OHdG and NFkB immunopositivity was detected in brain tissues exposed to linuron. • Linuron exposure causes oxidative and histopathological damage in brain tissues. • Linuron may disturb the biochemical and physiological functions of fish.
