Penelitian ini bertujuan untuk mengetahui pengaruh pemberian Cacing Sutra (Tubifex sp.), Cacing Darah (Larva Chironomus sp.), dan Grindalworm (Enchytraeus buchholzi) terhadap pertumbuhan dan kualitas warna benih ikan Channa limbata. Penelitian menggunakan Rancangan Acak Lengkap dengan tiga perlakuan dan tiga ulangan. Perlakuan dalam penelitian ini meliputi P1 (cacing sutra), P2 (cacing darah) dan P3 (grindalwormi). Benih Channa limbata yang digunakan berumur 15 hari. Benih ditebar dalam wadah dengan volume 8 L sebanyak 8 ekor/wadah. Benih dipelihara selama 45 hari dan diberi pakan sesuai perlakuan dengan dosis 20% sebanyak satu kali sehari. Pemberian pakan dilakukan pada pagi hari pukul 08.00. Sampling pertumbuhan dan kualitas air dilakukan setiap 15 hari. Pengelolaan kualitas air dilakukan setiap tiga hari dengan cara menyifon dan mengurangi air sebanyak 50?ri total volume wadah. Data sintasan dan pertumbuhan dianalisis menggunakan Analysis of Varians melalui aplikasi IBM SPSS. Hasil yang beda nyata pada tingkat signifikansi 95%, diuji lanjut dengan menggunakan Duncan Multiple Range Test. Hasil penelitian menunjukkan bahwa pemberian cacing sutra (Tubifex sp.), cacing darah (Larva Chironomus sp.), dan grindalworm (Enchytraeus buchholzi) memberikan pengaruh nyata terhadap pertumbuhan benih ikan Channa limbata. Hasil pertumbuhan terbaik diperoleh pada perlakuan pemberian grindalworm. Pemberian Cacing Sutra (Tubifex sp.), cacing darah (Larva Chironomus sp.), dan grindalworm (Enchytraeus buchholzi) memberikan pengaruh nyata terhadap nilai warna yellowness (b*) pada sirip benih ikan Channa limbata umur 2 bulan. Pemberian Cacing Sutra (Tubifex sp.) dan cacing darah (Larva Chironomus sp.) memberikan pengaruh terbaik terhadap nilai warna yellowness (b*) pada sirip benih ikan Channa limbata umur 2 bulan dengan nilai sebesar 7,5 pada perlakuan cacing darah, kemudian diikuti oleh pemberian cacing sutra dengan nilai sebesar 7,0.

This study aimed to evaluate the effects of feeding silkworms (Tubifex sp.), bloodworms (Chironomus sp. larvae), and grindalworms (Enchytraeus buchholzi) on the growth performance and body coloration of Channa limbata fry. The experiment employed a Completely Randomized Design (CRD) consisting of three dietary treatments with three replications. The treatments were P1 (silkworms), P2 (bloodworms), and P3 (grindalworms). Fifteen-day-old Channa limbata fry were stocked at a density of eight fish per 8-L container. The fish were reared for 45 days and fed once daily at 08:00 a.m. at a feeding rate of 20% of body weight according to their respective treatments. Growth performance and water quality were monitored every 15 days. Water quality management was carried out every three days by siphoning waste and replacing 50% of the culture water. Survival and growth data were analyzed using Analysis of Variance (ANOVA) in IBM SPSS software. When significant differences were detected at the 95% confidence level (P < 0>Tubifex sp.), bloodworms (Chironomus sp. larvae), and grindalworms (Enchytraeus buchholzi) significantly affected the growth performance of Channa limbata fry. The highest growth performance was achieved in the grindalworm treatment. The different live feeds also had a significant effect on the yellowness (b*) value of the fins in two-month-old Channa limbata fry. Feeding silk worms and bloodworms produced the highest fin yellowness (b*) values, with the bloodworm treatment recording the highest value (7.5), followed by the silkworms treatment (7.0).
