Abstract

Macroalgae Gracilaria sp. and Ulva sp. are commonly found, cultivated, and utilized to feed abalone in captivity. This study was aimed to evaluate the effect of two different macroalgae diet (Gracilaria sp. and Ulva sp.) on tropical abalone (Haliotis squamata). Two treatments of macroalgae diet (Gracilaria Gr and Ulva Ul) with six replications were performed at Research Center for Marine and Land Bioindustry, North Lombok. In this study, 25 tropical abalone (49.40, 0.21 mm) were kept indoor in each 60 liter rearing tank for 90 days between September to December. Macroalgae Gracilaria sp. outperformed Ulva sp. on specific growth rate (SGR) (0.18, 0.06), food conversion ratio (FCR) (7.14, 2.56) and survival rate (SR) (75.20, 6.86 %) of tropical abalone.
