Penelitian ini bertujuan untuk mengetahui pengaruh penambahan tepung tulang ikan lele Clarias sp. terhadap pertumbuhan dan sintasan benih lobster. Penelitian ini dilaksanakan pada bulan September sampai November 2024. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan empat perlakuan dan tiga kali ulangan, yaitu A (pakan kontrol), B (Tepung Tulang Ikan Lele 2%), C (Tepung Tulang Ikan Lele 4%), D (Tepung Tulang Ikan Lele 6%). Parameter yang diiuji meliputi pertumbuhan mutlak, laju pertumbuhan harian (SGR), kelangsungan hidup (SR), rasio konversi pakan (FCR). Kualitas air meliputi pH, DO, suhu dan amoniak. Analisis data menggunakan One-Way ANOVA dengan Tingkat kepercayaan 95%, menunjukkan bahwa lobster air tawar dengan perlakuan penambahan tepung tulang ikan lele Clarias sp. tidak
berpengaruh nyata terhadap pertumbuhan dan sintasan benih lobster air tawar Cherax quadricarinatus (P>0,05).
This study aims to determine the effect of the addition of catfish bone meal Clarias sp. on the growth and survival of lobster seeds. This research was conducted from September To November 2024. This study used a completely randomized design (CRD) with four treatments and three replications, namely A (control feed), B (2% catfish bone meal), C (4% catfish bone meal), D (6% catfish bone meal). Parameters tested included absolute growth, daily growth rate (SGR), survival (SR), feed conversion ratio (FCR). Water quality included pH, DO,
temperature and ammonia. Data analysis using One-Way ANOVA with a 95% confidence level, showed that crayfish with the treatment of adding catfish bone meal Clarias sp. did not significantly affect the growth and survival of crayfish seeds Cherax quadricarinatus (P>0.05).
