Morfoanatomi Ikan Patin (Pangasianodon Hypophthalmus) Yang Dipelihara Dengan Kombinasi Manipulasi Fotoperiod Dan Sistem Bioflok

Abstract
Pangasianodon hypophthalmus may grow well in short photoperiod/ dark condition. Unfortunately the dark conditionhampered thephytoplankton growth andcausingwater quality decrement.The application of biofloc system is expected to improve the water quality andenable fish to grow well and healthyas shown by its morphoanatomical condition. A factorial CRD design with 2 factors, namely biofloc (F) and non-bioflock (NF) and 3 treatments namely natural (control), 18D (18 hours dark) and 24D (24 hours dark) were applied. There was 3 repetitionsin each treatment. Parameters measured were water quality parameters, survival rate (SR) and morphoanatomical characteristics such as totallength (TL), body weight (BW), condition factor (CF), liver condition (color, texture, and hepatosomatic index/ HSI), vicerasomatic index (VSI) and gonadosomatic index (GSI). Results shown that the water quality in the biofloc treated water (BOD5 7.29-7.68 mg/l, ammonia 1.09-1.92 mg/l, nitrate 2.43-2.63 mg/l, phosphate 18.88-25.20 mg/l) was better than that of the non-bioflock (BOD5 35.22-47.54 mg/l, ammonia 2,59-6.05 mg/l, nitrate 2.73-4.54 mg/l, phosphate58.95- 64.88 mg/l). However, the fish survival of the biofloc treated media was lower than that of the non biofloc treated water, 90 % and 98 % respectiely. As wel as the surival, thebest result of fish growth werebetter in the non bioflock treatment.In 24DNF (24 hours dark with no flock), they were 100 % SR , 19.11 cm TL, 82.43 gr BW and 1.18 CF. The morphoanatomical condition of fish in all treatment were not different.The survival rate data shown that biofloc system may not suitable for P. hypophthalmus.
