IMO has developed international legislation international convention for the control and management of ship's ballast water and sendiment,2004 (adopted on 13 feb 2004): -Ballast water containts a variety of organisms including bacteria and viruses -approx 10 billion tons ballast water have been transfered per year -seriuos ecological,economic,and health impact on the receiving environment -these were caused by ballast water discharge by ship Capt.Sjafrizal,M.Mar
