Abstract

Effect of growth and survival rate on different densities in the cage culture of juvenile abalone (Haliotis discus hannai) were determined in Myoduri Yeosu, Jeollanamdo from April 2000 to April 2001. The shell length growth was conducted using $32.35{\pm}1.35$ mm abalone juveniles for 374 days at densities $15{\%}\;(230\;indv./m^{2}),\;30{\%}\;(460\;indv./m^{2}),\;45{\%}\;(690 \;indv./m^{2}),\;60{\%}\;(920\;indv./m^{2})$. The result showed that the hightest growth rate was observed in lowest $(15{\%})$ density experimental group. Survival rate of Juvenile abalone was the highest in $15{\%}$\; density group and lowest in $45{\%}$ density group and distribution rate of shell length showed the highest as $30{\%}\;in\;230\;indv./m^{2}\;(15{\%})$ group.
