<p class="NoParagraphStyle" align="center"><strong>ABSTRACT</strong></p><p class="NoParagraphStyle" align="center"><strong> </strong></p><p>This study was carried out to evaluate growth performancce of eel (<em>Anguilla bicolor bicolor</em>) at the density of 2 g/L, 3 g/L, and 4 g/L in the recirculation system. The experimental design used was completely randomized design with three replications. The eel used for this study was <em>Anguilla bicolor bicolor </em>at stadia elver with average body weight of 3 g/fish. Fish were reared for 60 days. Analysis of the blood profile and blood glucose level were done every ten days, while cortisol measurement was performed three times on the day-0, 30, and 60. Results showed that stocking density affected biomass growth. The best stocking density was 4 g/L with the growth of 10.62 g biomass/day, the specific growth of 1.47%, 1.16 feed conversion, and survival of 96.24%. All treatments did not give significant effect on the blood glucose and cortisol level.</p><p> </p><p>Keywords: elver, stocking density, growth, stress response, recirculation system</p><br /><p class="NoParagraphStyle"> </p><p class="NoParagraphStyle"> </p><p class="NoParagraphStyle" align="center"><strong>ABSTRAK</strong></p><p class="NoParagraphStyle" align="center"> </p><p>Penelitian ini dilakukan untuk mengevaluasi kinerja pertumbuhan ikan sidat (<em>Anguilla bicolor bicolor</em>) dengan padat tebar 2 g/L, 3 g/L, dan 4 g/L dalam sistem resirkulasi. Rancangan percobaan yang digunakan adalah rancangan acak lengkap dengan tiga ulangan. Ikan sidat yang digunakan adalah spesies <em>Anguilla bicolor bicolor </em>stadia elver dengan bobot rata-rata 3±1 g/ekor. Pemeliharaan dilakukan selama 60 hari. Analisis gambaran darah dan glukosa darah dilakukan setiap sepuluh hari sekali, sedangkan pengukuran kortisol dilakukan sebanyak tiga kali yaitu pada hari ke-0, 30, dan 60. Hasil penelitian menunjukkan bahwa perlakuan padat tebar berpengaruh nyata terhadap laju pertumbuhan biomassa. Padat tebar terbaik adalah 4 g/L dengan laju pertumbuhan biomassa 10,62 g/hari, laju pertumbuhan spesifik 1,47%, konversi pakan 1,16, dan sintasan 96,24%. Semua perlakuan padat tebar tidak memberikan pengaruh yang nyata terhadap kadar glukosa darah dan kortisol.</p><p> </p><p>Kata kunci : elver, padat tebar, pertumbuhan, respons stres, sistem resirkulasi</p>
