Abstract

Penelitian bertujuan untuk mengetahui sistem pergantian air yang paling baik pada pemeliharaan benih ikan betutu. Wadah penelitian: 12 unit bak kayu berlapis plastik (1,9m x 0,8m x 0,5m) diisi air 500 L, ditempatkan dalam ruang terlindung dan dilengkapi dengan aerasi. Hewan uji: benih ikan betutu ukuran bobot 0,96±0,08 g/ekor, padat tebar 1 ekor/5 liter air, diberi pakan alami secara berlebih dengan waktu pemeliharaan selama 12 minggu. Perlakuan berupa perbedaan sistem pergantian air: (a) resirkulasi, (b) semi-statis, dan (c) continous flow. Parameter yang diukur: sintasan, pertumbuhan, dan produktivitas benih ikan betutu serta sifat fisika-kimia air pemeliharaan. Hasil penelitian menunjukkan bahwa pergantian air dengan sistem resirkulasi memberikan sintasan yang paling baik terhadap benih ikan betutu (33,0%) dibanding continous flow (28,3%) dan berbeda nyata (P<0,05) dengan sistem semi-statis (21,3%). Laju pertumbuhan spesifik benih ikan betutu antara perlakuan tidak berbeda nyata (P>0,05) dengan nilai secara berturut-turut sebesar: 1,41%; 1,31%; dan 1,50%.The aim of this experiment is to obtain the information on survival rate and growth of sand goby fries. The experiment was conducted at research station CibalagungBogor. Twelve container of 1.9m x 0.8m x 0.5m were used in this experiment, each container was stocked with 1 fish/5L of sand goby fry with 0.96±0.08 gram weight. Three different water exchange were aplied i.e (a) recirculation, (b) semi static, and (c) continous flow. Each treatment was done in three replicates. The result showed that the recirculation gave the best result on survival rate (33.0%) compared with continous flow (28.3%) and significantly different from semi static (21.3%).
