The use of artificial feed in Haliotis squamata farming in submerged cage culture system at Lae-Lae island, Makassar

This study investigated the use of a combined formula artificial feed and fresh marine algae Gracilaria sp in submerged cage culture system its effect on Haliotis squamata relative growth survival rates. The experiment was performed Lae-Lae Island, Makassar from May to October 2016. sample Abalone juvenile larvae were 1.5 cm size stocked at density 30 pcs/cage. x 15 7 equipped with 2-inch Paralone pipe. employed completely random design (CRD) 3 treatments replicates. applied treatment included combination sp. Each included: A. 25% + 75% algae, B. 50% C. given proportion 20% abalone's weight. results indicated that (Gracilaria sp.) had no significant rates squamata. Although did not significantly affect rate, descriptively, A contributed most optimal rate compared B
