Abstract: 

Mercury accumulation and its effects on kidney and gill of golden grey mullet, Lize aurata, fry were investigated. The fry (1.5-2g) were caught from Iranian coasts of the Caspian Sea (Noor) on April 2005. They were held in a 4001 tank, with continuously aerated Caspian Sea water for at least 4 days prior to experiment. Each experiment began with the transfer of 20 fishes from the stock tank to the experimental aquariums (50L) contain, 0, 50, 100, 350 ppb of HCl2. No mortality was observed on 0, 50 and 100 ppb exposed groups following 96 hours. Hg concentrations were 549.5, 1893.1 and 3364.7 ppb in the gills of control, 50 and 100 ppb group, respectively. Mass mortality observed in 350 ppb exposed group following 2 hours and Hg concentration in the gills was 15300.2 ppb. In all Mercury treated groups, lifting epithelial cells from lamellae, lifting and rupture basal membranes of epithlia cells, hypertrophy and hyperplasia of gills cells were observed. Fishes exposed to 350 ppb also showed gills cells neerosis. Glomerulu’s capillary dilation and vacuolation of the proximal tubule cells of kidney were observed in the all Mercury treated groups.
