Abalone (Haliotis sp. ) are one of high economy value commodity in fisheries among others. This is due to the high demand for this commodity in export market, such as Singapore, Hongkong, China, Taiwan, Japan. This high demand for the commodity lead to the excessive caught of abalone in wild, that can cause the scarcity of the stock, hence a preventive action need to be done. Marine Aquaculture Development Centre (MADC) Lombok, as one of Technical Implementing Unit under Ministry of Marine Affairs and Fisheries (MMAF) Indonesia, have a solution to this problem by doing the abalone mass rearing using hanging compartment method.
The high demand for the abalone can only be fulfilled by the high number of productions, thus farmers participation is a must. The idea behind the method is to produce a mass scale of abalone using a method that can be imitate easily by the farmers. This method using a number of perforated plastic bucket, hanged to the floating platform with Poly Ethylene (PE) rope as a suspender (Figure 1) .
Observation for data collection was done from July 7th till July 28th 2023 (21 days) , in MADC-Lombok Facility. Data that has been collected including the stocking density, specific growth rate (SGR) for weight, Absolute Length Growth, Survival Rate (SR), and Feed Conversion Ratio (FCR). During the rearing phase, the abalone fed only using Gracillaria sp. (Figure 2), 3 times a week with feeding dose as much as 30% of biomass , stocking density for each bucket is 200 abalones (Haliotis squamata ) with average shell length 3,6 cm (Figure 3). The result from the observation for SGR, Absolute Length Growth, SR, and FCR respectively as follows: 0,83%; 0,351; 99,56%; 22,5.
