Abstract
A comparative study on the nursery culture of tropical oyster spat Crassostrea belcheri (G.B. Sowerby II 1871) in plastic mesh nets suspended vertically and horizontally was conducted for 45 days. The results revealed no difference in absolute growth rate of shell width between both hanging methods. Spat suspended vertically showed higher absolute growth rate of shell length and instantaneous growth rate than those suspended horizontally. No significant difference was found between the mean survival rate of vertically (78.8±3.4%) and horizontally suspended (76.0±8.2%) spat. The vertically suspended net showed a higher fraction of spat larger than 1.22 cm than those in the horizontally suspended nets.
