Ikan sidat (Anguilla bicolor) adalah organisme karnivora yang memiliki dua habitat yaitu perairan tawar dan perairan laut. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan tepung maggot dan probiotik dalam pakan terhadap pertumbuhan ikan sidat. Penelitian ini dilaksanakan di Balai Pembenihan Budidaya Air Payau Ujung Batee pada 9 Februari – 20 Maret 2023. Penelitian ini dilakukan menggunakan metode Rancangan Acak Lengkap dengan 4 perlakuan dan 4 kali ulangan, yaitu perlakuan A (Kontrol), perlakuan B (TM 50% + Probiotik 15 ml), perlakuan C (TM 60% + probiotik15 ml) dan Perlakuan D (TM 70% + Probiotik 15 ml). Pemeliharaan ikan dilakuakan selama 40 hari dengan frekuensi pemberian pakan dua kali sehari. Hasil penelitian menunjukkan bahwa perlakuan terbaik diperoleh pada perlakuan B dengan penambahan tepung maggot 50% dan probiotik 15 ml/kg pakan menghasilkan pertambahan panjang mutlak 1,36 cm, pertambahan bobot mutlak 0,13 g, laju pertumbuhan spesifik 2,05 g, rasio konversi pakan 1,61, efesiensi pakan 61,84%, kelangsungan hidup 82,50%. Perlakuan terendah diperoleh pada perlakuan D dengan penambahan tepung maggot 70% dan probiotik 15 ml/kg pakan sehingga berpengaruh buruk terhadap laju pertumbuhan benih ikan sidat.

The eel (Anguilla bicolor) is a carnivorous organism that has two habitats, namely freshwater and marine waters. This study aims to determine the effect of adding maggot flour and probiotics in feed on the growth of eels. This research was conducted at the Ujung Batee Brackish Water Culture Hatchery Center in February 2023-March 2023. This research was conducted using a completely randomized design with 4 treatments and 4 repetitions. Fish rearing was carried out for 40 days with a frequency of feeding twice a day. The results showed that the best treatment was obtained in treatment B with the addition of 50% maggot flour and 15 ml/kg of feed probiotics resulting in an absolute length gain of 1,36 cm, an absolute weight gain of 0,13 g, a specific growth rate of 2,05g, a conversion ratio feed 1,61, feed efficiency 61,84%, survival 82,50%. The lowest treatment was obtained in treatment D with the addition of 70% maggot flour and probiotics 15 ml/kg of feed so that it adversely affected the seed growth rate eel.
