Glukosa Darah dan Kelangsungan Hidup Benih Leptobarbus Hoevenii Pada Sistem Resirkulasi

The purpose of this study was to determine the optimal density of jelawat (L. hoevenii Blkr) fry in rearing with a recirculation system. This study used a completely randomized design (CRD) with 4 treatments and 3 replications, where the treatments were: Treatment A: stocking density 5 fish/L, Treatment B: stocking density 10 birds/L, Treatment C: stocking density 15 birds/L and Treatment D : Stocking density of 20 fish/L. Parameters observed were survival, blood glucose and water quality. The results showed that the average blood glucose was 56 mg/dl and the average survival of jelawat fish was 99.62%. The results of water quality measurements show that the temperature ranges from 28.5o-29 oC, water pH ranges from 6.4-6.7, dissolved oxygen ranges from 5-5.4 ppm, carbon dioxide values ranges from 2.1-5.1 ppm, ammonia ranges from 0.0011-0.0018.
