      Abstract
      Ikan tawes Barbonymus gonionotus adalah jenis ikan air tawar yang populer dibudidayakan karena memiliki nilai ekonomis yang tinggi. Upaya peningkatan pertumbuhan dan kelangsungan hidup ikan dapat dilakukan melalui penambahan probiotik pada pakan. Penelitian ini bertujuan untuk mendapatkan probiotik komersial terbaik dalam meningkatkan kinerja pertumbuhan dan sintasan ikan tawes. Penelitian menggunakan metode rancangan acak lengkap dengan tiga perlakuan yaitu kontrol (tanpa probiotik), probiotik A (6 mL kg?¹ pakan), dan probiotik B (15 mL kg?¹ pakan), masing-masing tiga ulangan. Parameter yang diamati meliputi pertumbuhan, rasio konversi pakan, sintasan, hematologi, kepadatan bakteri usus, kualitas air, dan analisis usaha. Hasil menunjukkan perlakuan probiotik A menghasilkan performa terbaik yaitu pertumbuhan bobot mutlak 13,6 g, pertumbuhan panjang mutlak 4,4 cm, laju pertumbuhan harian 3,96% hari?¹, rasio konversi pakan 1,02, dan tingkat kelangsungan hidup 98,6%. Analisis usaha juga menunjukkan keuntungan tertinggi pada perlakuan A dengan R/C 1,51. Kualitas air selama pemeliharaan tetap berada dalam rentang ideal untuk budidaya ikan air tawar.
       
      Tawes fish Barbonymus gonionotus is a popular freshwater fish species cultivated due to its high economic value. Efforts to enhance fish growth and survival can be achieved by incorporating probiotics into the feed. This study aimed to identify the most effective commercial probiotic for improving the growth performance and survival rate of tawes fish. The research employed a completely randomized design with three treatments: control (without probiotic), probiotic A (6 mL kg?¹ feed), and probiotic B (15 mL kg?¹ feed), each with three replications. Observed parameters included growth, feed conversion ratio (FCR), survival rate, hematology, intestinal bacterial density, water quality, and economic analysis. Results indicated that probiotic A treatment yielded the best performance, with absolute weight gain of 13,6 g, absolute length gain of 4,4 cm, specific growth rate (SGR) of 3,96% day?¹, FCR of 1,02, and survival rate of 98,6%. Economic analysis also showed the highest profit in treatment A, with an R/C ratio of 1,51. Water quality parameters during the rearing period remained within the optimal range for freshwater fish aquaculture.
