      Abstract
      Ikan koridoras albino Corydoras aeneus merupakan salah satu komoditas ikan hias air tawar yang banyak diminati oleh para penggemar ikan hias. Produktivitas ikan ini tergolong masih rendah maka dari itu permintaan pasar yang tinggi belum dapat terpenuhi. Penelitian ini bertujuan menentukan produksi terbaik ikan koridoras albino pada sistem pergantian air dengan persentase pergantian 20%, 30% dan 40% dengan padat penebaran 1.000 ekor m-2 , dengan tiga ulangan. Ikan koridoras yang digunakan memiliki rata-rata 0,21±0,02 g dan panjang rata-rata 1,44±0,05 cm. Ikan diberi pakan Tubifex sp. dua kali sehari, pakan diberikan dengan metode at satiation, selama masa pemeliharaan 60 hari. Hasil penelitian menunjukkan bahwa produksi terbaik terdapat pada persentase pergantian air sebanyak 40%/hari dengan nilai kelangsungan hidup 93,73±0,42% dan laju pertumbuhan spesifik 4,55±0,14%. Berdasarkan perhitungan analisis usaha persentase pergantian air 40% menghasilkan keuntungan per siklus paling tinggi yaitu Rp85.180.064
       
      The albino Corydoras catfish (Corydoras aeneus) is one of the popular freshwater ornamental fish commodities among fish enthusiasts. However, the productivity of this fish is still relatively low, and as a result, the high market demand cannot be fully met. This research aims to determine the best production for albino Corydoras catfish in a water exchange system with exchange percentages of 20%, 30%, and 40% at a stocking density of 1.000 individuals per square meter, with three replicates. Fish were stocked at initial weight of 0,21±0,02 g, and initial length of 1,44±0,05 cm. The fish fed Tubifex sp. twice daily at satiation for 60 days culture period. The results indicate that the best production was achieved with a 40% daily water exchange rate with survival rate of 93,73±0,42% and specific growth rate of 4,55±0,14%. Based on the business analysis, 40% water exchange treatment resulted in the highest profit per cycle, which was Rp85.180.064
