Abstract :The effects of the calcium concentration on chloride cell insert ignore into journalissuearticles values(mitochondria-rich cell); density in the gills of brown trout insert ignore into journalissuearticles values( Salmo trutta L.); larvae were studied. For this purpose, animals were divided into 3 groups 2 weeks after hatching and each groups was exposed to different calcium concentrations of water for two weeks. The results showed that the number of chloride cells in gill arch epithelia of larval fish increased with decreased calcium concentration.This increase was statistically significant in the gills of larvae kept in zero-Ca 2+ freshwater insert ignore into journalissuearticles values(ZCWF); insert ignore into journalissuearticles values( P< 0.001 ); and of those kept in low-Ca 2+ freshwater insert ignore into journalissuearticles values(LCFW); insert ignore into journalissuearticles values( P< 0.05); in comparision with the gills of larvae kept in normal freshwater insert ignore into journalissuearticles values(NFW);.
