The current study was carried out on zebrafish embryos at 6 h post fertilization exposing them 24 h to five concentrations (0 [negative control], 5, 10, 50, 80, 100,and 200 ppb Hg cl. Zebrafish embryos exposed to2% ethanol were positive controls (100% embryonic death). Embryos were assessed at 30, 54, 72 and 96 h post fertilization for progress in development, morphometry and morphological deformities. Embryos exposed to 5 ppb methyl mercury were healthy, showed no obvious deformities. Embryos exposed to 10, 50, 80, 100, and 200 ppb hg cl showed lighter pigmentation and smaller eyes. Embryos exposed to 80, 100, and 200 ppb hg cl showed shorter larval length.Larger yolk sac was recorded in embryos exposed to 80 ppb hg cl.Twisted tail was seen in embryos exposed to 80, 100, and 200 ppb hg cl.
