Abstract
In this study Abalone (Haliotis asinina) spat stage larvae were reared in three different densities: 100, 200 and 300 larvae/stick (equivalent to 1 - 5 units/ml). Food use was Navicula sp. After 30 days of experiment, the results showed that the densities of 100 and 200 spat stage larvae/stick had high growth and survival rate (no statistical difference). The length of the shell size is about 3.27 mm and 3.35 mm having the survival rate is 62.0% and 68.1%, respectively. At that time, with the density of 300 spat stage larvae/stick the length of the shell size is about 2.65 mm and the survival rate is 40.9%.
