Radiation at very low doses frequently has a stimulating or hermetic effect on growth of organism. Effects of growth and survival rate on various dose of gamma irradiation in the farm culture of juvenile abalone (Haliotis discus hannai) were determined in Hallim (Jeju) from February 2004 to January 2005. The initial shell length of abalone juveniles in this study was average $3.45{pm}0.4cm$. A change of growth after irradiation $(0{sim}20Gy)$ was observed for 48 weeks. The highest growth rate was observed in 4 Gy-irradiated group and the lowest growth rate was observed in 20 Gy-irradiated group. The additional research about biochemical changes on juvenile abalone after irradiation should be accomplished. Continuous study for gamma radiation-induced hormesis on growth and metabolism of juvenile abalone will further induce the creation of value in ocean industry.
