The survival rates of the staghorn coral Acropora muricata and the branching coral Pocillopora dami-cornis were examined using 6 transplantation techniques to evaluate the effectiveness of direct transplantation of coral fragments vs. fragments grown in nurseries before transplantation. (n＝150 fragments per technique). The study was conducted at Sungwan beach, Koh Laan, Pattaya City, Chonburi Province for a period of 33 weeks (September 2009 to May 2010). In A. muricata, the high-est survival rate (82.0%) was shown by those fragments which were nursed on the mid-water nursery before transplanted on iron plate, followed by those which were directly transplanted on iron plate (survival rate of 64.7%), and those nursed on iron fish home nursery before trans-planted on iron plate, (survival rate of 59.3%). In P. damicornis, the highest survival rate (72.7%) was shown by those fragments which were nursed on the iron fish home nursery before transplanted on iron plate, followed by those which were nursed on mid-water nursery before transplanted on coral ball (survival rate of 64%), and those directly transplanted on coral ball, (survival rate of 46.7%). According to survival rate, budget, time frame and manpower, the most effective method was direct transplantation on iron plate.
