Effects of mercury on embryonic development and larval growth of the sea urchin Echinometra mathaei from the Persian Gulf
This study investigated the effects of increasing mercury (Hg) concentration on early developmental stages of sea urchin, Echinomethra mathaei, as a bioindicator. The toxicity test was carried out after the gamete released induction and fertilization in six concentrations of mercury within the range of 4, 8, 16, 32, 64 and 128 µg/L. Embryos samples were incubated for 30 h in control and test so...

متن کاملDetermination of developmental stages of embryo in the Sea Urchin, Echinometra mathaei
Sea Urchin is one of the most useful tools in developmental biology studies because this organism has the simplest kind of developmental stages. We aimed to determine developmental stages and timetable of Echinometra mathaei embryo (the species of Persian Gulf). The spawning of E. mathaei was induced by 0.5M KCl injection (1ml) into the coelomic cavity. After fertilization, embryos were placed ...

متن کاملAntibacterial activity of various extracts of the sea urchin Echinometra Mathaei
This study was conducted for determination of antibacterial effect of Echinometra mathaei extraction on human disease bacteria. Samples were collected in Abu Mosa Island. Extraction operation was done by shell, spines, gonad and aristotle's lantern. Ethyl acetate, n-hexane and methanol were used for extraction operation respectively. Extraction effect of these organs was investigated on Vibrio ...
