The experimental designed CRD with four treatments (calcium carbonate addition with dose A, 0 mg/L; B, 50 mg/L;  C, 100 mg/L; and D, 150 mg/L) and three replications. The eel with body weight average of 10.3±0.16 g/individual cultured in aquariums (100×50×40 cm³) with 4 g/L of stocking densities. This study was conducted for 60 days, in which the eel were fed three times a day by at satiation method. The result of this study showed that treatment B with calcium carbonate addition of 50 mg/L in to the culture media was the best treatment for production performance (survival rate 99.1%; biomass growth rate 3.48 g/day; and food conversion ratio 3.5). It was also optimal to reduce the physiological responses of the eel, in which the oxygen consumption rate ie 0.36 mg O₂/g/jam and osmotic work rate ie 0.22 mOsm/L H₂O. For the coefficient of diversity, the best results occur in treatment D ie 23.3%. Water quality during the study are within the range of optimal maintenance of eels (temperature 29.8–31.73 °C; pH 7.4–8.1; dissolved oxygen 4.7–5.57 mg/L; nitrite 0.10–0.78 mg/L; and ammonia 0.0008–0.0281 mg/L).</p><p class="NoParagraphStyle"> </p><p class="NoParagraphStyle">Keyword : <em>Anguilla bicolor bicolor</em>, calcium carbonate, Indonesian eel, production performance</p><p class="NoParagraphStyle"> </p><p class="NoParagraphStyle"> </p><p class="NoParagraphStyle" align="center"><strong>ABSTRAK</strong></p><p class="NoParagraphStyle"><strong> </strong></p><p class="NoParagraphStyle">Penelitian ini bertujuan mengkaji pengaruh penambahan kalsium karbonat (CaCO₃) pada media budidaya terhadap kinerja produksi (derajat kelangsungan hidup, laju pertumbuhan mutlak biomassa, rasio konversi pakan, dan koefisien keragaman) ikan sidat <em>Anguilla bicolor bicolor</em>. Rancangan penelitian yang digunakan adalah RAL dengan empat pelakuan (penambahan CaCO₃dengan dosis A, 0 mg/L; B, 50 mg/L; C, 100 mg/L; dan D, 150 mg/L) dan tiga ulangan. Ikan sidat yang digunakan memiliki bobot rata-rata 10,3±0,16  g/ekor dengan padat tebar 4 g/L yang dipelihara pada wadah akuarium berukuran 100×50×40 cm³. Pemeliharaan ikan sidat dilaksanakan selama 60 hari dan diberikan pakan tiga kali sehari dengan metode <em>at satiation</em>. Hasil penelitian menunjukkan bahwa perlakuan B, yaitu penambahan CaCO₃ dengan dosis 50 mg/L adalah perlakuan terbaik terhadap kinerja produksi ikan sidat (derajat kelangsungan hidup 99,1%; laju pertumbuhan mutlak biomassa 3,48 g/hari; dan rasio konversi pakan 3,5). Perlakuan B juga memberikan nilai yang optimal yang dapat menurunkan tingkat konsumsi oksigen (0,36 mg O₂/g/jam) dan tingkat kerja osmotik (0,22 mOsm/L H₂O). Untuk parameter koefisien keragaman, hasil terbaik terjadi pada perlakuan D sebesar 23,3%. Kualitas air selama penelitian berada dalam kisaran optimal pemeliharaan ikan sidat (suhu 29,8–31,73 ^oC; pH 7,4–8,1; oksigen terlarut 4,7–5,57 mg/L; nitrit 0,10–0,78 mg/L; dan amonia 0,0008–0,0281 mg/L).</p><p class="NoParagraphStyle"> </p><p>Kata kunci :<strong><em> </em></strong><em>Anguilla bicolor bicolor</em>, ikan sidat, kalsium karbonat, kinerja produksi</p>
