Biota yang digunakan dalam penelitian ini adalah kerang totok ukuran 3-4 cm yang diperoleh dari perairan sekitar P. Gombol, Segara Anakan, Cilacap. Wadah yang digunakan adalah akuarium berukuran 30x30x30 cm dengan volume media 2 liter. Metode yang digunakan adalah eksperimental laboratorium dengan rancangan acak lengkap, 3 perlakuan dan 3 ulangan, yaitu campuran T. chuii 36 x 104 sel/ml dan S. costatum 9 x 104 sel/ml (pakan T1); T. chuii 27 x 104 sel/ml dan S. costatum 18 x 104 sel/ml (pakan T2) dan T. chuii 18 x 104sel/ml dan S. costatum 27 x 104 sel/ml (pakan T3). Pakan diberikan sekali sehari, pemeliharaan dilakukan selama 3 bulan. Pengukuran berat yang dilakukan seminggu sekali dan dianalisis Specific Growth Rate (SGR) dan Food Convertion Ratio (FCR). Hasil penelitian menunjukkan bahwa campuran pakan T. chuii dan S. costatum memberikan pengaruh pertambahan berat yang berbeda nyata (p< 0,05), tetapi tidak memberikan pengaruh yang nyata terhadap SGR dan FCR kerang Totok (p > 0,05). Pakan campuran T. chuii 27 x 104 sel/ml dan S. costatum 18 x 104 sel/ml meningkatkan nilai SGR namun mempunyai nilai FC yang besar. Kata kunci : Kerang Totok, Polimesoda erosa, Tetraselmis chuii , Skeletonema costatum Knowledge on ideal feeding dose for kerang totok P. erosa is needed to improved the use of microalgae diet and to investigate the most efficient natural feeding dose of T. chuii and S. costatum on growth of kerang totok ( P. erosa ). The organism used on this study was Kerang Totok size 3-4 cm which harvested from P. Gombol, Segara Anakan, Cilacap. Experiment was conducted in 30cm x 30cm x 30 cm aquarium filled with 2 liter of water each. A fully randomized design of laboratorium experimental method was applied for the study with three treatment i.e; 36 x 104 cell/ml T. chuii : 9 x 104 cell/ml S. costatum (T1); 27 x 104 cell/ml T. chuii : 18 x 104 cell/ml S. costatum (T2) and 18 x 104cell/ml T. chuii : 27 x 104 cell/ml S. costatum (T3), single feed dose per day at 08.00 WIB for 3 month period. Three replications were set up for each treatment. Parameter measured during the study were weight (weekly measurement), Specific Growth Rate (SGR) and Food Convertion Ratio (FCR). The result showed that feeding dose of T. chuii and S. costatum significantly affect the mean weekly weight gain (p< 0,05) but not to mean of SGR or FCR (p > 0,05). Mixture of 27 x 104 sel/ml T. chuii : 18 x 104 sel/ml S. costatum) tend to increase the SGR values but give bigger FCR during the study period.
