Abstract
Terdapat beberapa masalah dalam budidaya nilem seperti kualitas telur yang rendah, kurangnya kontinuitas telur, dan terbatasnya waktu pemijahan. Penelitian ini bertujuan untuk mengevaluasi performa reproduksi dan pertumbuhan bobot mutlak nilem melalui metode oral dengan penambahan hormon pertumbuhan rekombinan kerapu kertang. Rancangan penelitian meggunakan lima perlakuan: tanpa kuning telur, phosphate buffer saline, dan tanpa r-ElGH (A, kontrol negatif), dengan penambahan kuning telur, phosphate buffer saline, dan dosis r-ElGH berbeda (0, 20, 35, 50 mg/kg pakan; B, C, D, dan E) dengan ulangan individu. Hasil penelitian menunjukkan bahwa penambahan r-ElGH berpengaruh nyata terhadap performa reproduksi: meningkatkan fekunditas 28,84 % dan meningkatkan pertumbuhan bobot mutlak 14,32 % pada nilem betina dibandingkan dengan kontrol negatif. Kata Kunci: fekunditas, hormon pertumbuhan rekombinan, kualitas telur, betina, nilem ABSTRACT There are several problems during Nilem culture, such as low egg quality, lack of egg continuity, and limited spawning time. This study aims to evaluate the reproductive performance and absolute body growth of nilem by oral treatments with the addition of recombinant giant grouper. The study design used 5 treatments: without egg yolks, phosphate buffer saline, and without r-ElGH (A, negative control), with the addition of egg yolks, phosphate buffer saline, and different r-ElGH dose (0, 20, 35, 50 mg/kg of feed; B, C, D, and E) with individual replications. The result showed that the addition of r-ElGH significant affected on reproductive performance with increasing fecundity 28,84 % and increasing absolute body growth 14,32 % in female nilem compared with negative control. Key words: fecundity, recombinant growth hormone, egg quality, female, nilem
