摘要： The study was planned to investigate DNA fragmentation in fish to screen aquatic toxicity and in Epinephalus chlorostigma and Scamberomorus commerson collected from Red sea near Jizan, Saudi Arabia from three locations "(Corniche North park: "16.92161, 42.54631; Jizan Port: 16.874, 42.54952" N and Jizan Economic City: 17.26589, 42.34738"")"were used as a case study for the application of comet assay. The study area of the Red Sea is polluted due to anthropogenic activities and the disposal of wastes from multiple sources. Comet and micronucleus assays were used to detect genotoxicity in these fish species harvested from three sites. The concentration of Pb, Cr, Zn, Mn, Cu, Cd, Sn, and Hg was higher in the water samples collected from the polluted site compared to the non-polluted site of the Red sea. Comet assay for S. commerson showed significant (p < 0.05) genetic damage about 44.33 +/- 3.03% DNA in comet tail at site S1. It was subsequently reduced to 31.71 +/- 3.52% and 22.11 +/- 2.52% at sites S2 and S3. E. chlorostigma also showed significant DNA in comet tail as 17.34 +/- 2.19%, 11.87 +/- 3.01%, and 36.41 +/- 3.98% at site S1-S3, respectively. Significant (p < 0.05) DNA damage was observed in the fishes procured from non-polluted locations and upstream locations. The micronucleus induction in E. chlorostigma was recorded as 23.20 +/- 4.19 and 2.20 +/- 0.58%, respectively, non-polluted and polluted sites. S. commerson exhibited significant differences between polluted and non-polluted sites (44.80 +/- 3.73 and 8.20 +/- 2.20%) polluted and upstream (44.80 +/- 3.73 and 20.60 +/- 4.02%), respectively. A significant difference was obtained between E. chlorostigma and S. commerson for nuclear abnormalities S. commerson showed higher frequencies for nuclear deformities than E. chlorostigma. S. commerson showed substantial micronucleus induction frequencies collected from an area of low pollution intensity (upstream). This study showed that E. clorostigma and S. commerson could be successfully used as a bioindicator to determine the health of the Red Sea through the most specific assays such as comet and micronucleus tests as an early warning and to devise the monitoring strategies to ensure a safe supply of fish for human consumption.(c) 2021 The Author(s).
