      Abstract
      Ikan jurung Tor tambroides adalah ikan air tawar endemik dari famili Cyprinidae dengan nilai ekonomi tinggi. Namun, dalam proses budidayanya ikan jurung memiliki kendala berupa pertumbuhan yang lambat. Penelitian ini bertujuan menganalisis pengaruh padat tebar berbeda terhadap pertumbuhan dan kelangsungan hidup benih ikan jurung. Metode yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 ulangan yaitu K (10 ekor/L), PT3 (3 ekor/L), PT5 (5 ekor/L), dan PT7 (7 ekor/L). Hasil pengamatan menunjukkan bahwa pemeliharaan benih ikan dengan padat tebar 3 ekor/L mampu meningkatkan pertumbuhan panjang dan bobot mutlak sebesar 1,24±0,06 cm dan 0,11±0,00 g. Nilai pertumbuhan panjang dan bobot harian yang diperoleh sebesar 3,36±0,03 cm/hari dan 0,23±0,01 g/hari. Pemeliharaan dengan padat tebar berbeda tidak mempengaruhi tingkat kelangsungan hidup dan kualitas air dibuktikan dengan nilai kualitas air berada dalam rentang baku mutu. Penggunaan padat tebar 3 ekor/L mampu mengoptimalkan performa pertumbuhan benih ikan jurung
       
      Tor tambroides, commonly known as jurung fish, is a freshwater endemic species from the family Cyprinidae with high economic value. However, its cultivation faces challenges, particularly due to slow growth rates. This study aimed to analyze the effect of different stocking densities on the growth and survival of Tor tambroides juveniles. The experimental method used was a completely randomized design (CRD) with four treatments and three replications: K (10 ind/L), PT3 (3 ind/L), PT5 (5 ind/L) and PT7 (7 ind/L). The results showed that rearing juveniles at a stocking density of 3 ind/L significantly enhanced both absolute length and weight growth, reaching 1,24±0,06?cm and 0,11±0,00?g, respectively. The daily length and weight growth were recorded at 3,36±0,03?cm/day and 0,23±0,01?g/day. Stocking density had no significant effect on survival rate or water quality, as all measured water parameters remained within acceptable standards. Therefore, a stocking density of 3 ind/L was found to be the most effective in optimizing the growth performance of Tor tambroides juveniles
