The impact of mercuric ions (Hg(2+)) on prawn oocytes was examined. Prawn oocytes constitute an unusual system in that they are activated at spawning by seawater Mg(2+), which mediates correlated dynamic changes in intracellular free calcium concentration [(Ca(2+))(i)] and membrane conductance assoc
