Judul: Respons physiologis of catfish Pangasianodon hypopthalmus at different calsium concentration of media and its consequence on Survival rate and growth
Abstrak: Calcium is one of macromineral that needed by fish for physiological processes such as osmoregulation, enzyme regulation, ossification and cell permeability. This study aimed to determine the optimum concentration of calcium carbonate (CaCO3) at 3 ppt salinity of media and evaluated the effects of adding calcium to physiological conditions and the affect to the survival rate and growth of catfish. The study was conducted in two stages; the first stage was determined the optimum concentration of calcium, the second stage was evaluated the effect of calcium on the physiological condition of fish. Randomized completely design with four treatments and three replication; 3 ppt + 0 mg/L CaCO3, 3 ppt + 50 mg/L CaCO3, 3 ppt + 100 mg/ L CaCO3, 3 ppt + 150 mg/L CaCO3, were used in this study. The results showed that the salinity of media with the addition of calcium can reduce levels of osmotic performance, oxygen consumption, and blood glucose levels, and it can increase the feed efficiency and daily growth rate. Treatment 3 ppt + 100 mg/L showed the best physiological condition among other treatments.

Judul: Penambahan Kapur CaO pada Media Bersalinitas untuk Pertumbuhan Benih Ikan Patin
Abstrak: Lime CaO additional on rearing Pangas catfish in 4‰ media to decrease osmotic regulatory and less using energy for osmoregulation. Its excess energy could be used for growth. This research used fry with average length 2,59±0,02 cm and average weight 0,13±0,01 g. These fry contained in 15 units of rectangular glass aquaria 20x20x20 cm has been filled water with salinity of 4 ‰ and additional lime CaO appropriately kind of factor experiment (0 mg/ℓ, 20 mg/ℓ, 40 mg/ℓ, 60 mg/ℓ, and 80 mg/ℓ). Eighteen fry were stocked per tank. A single factor experimental design with three replication per treatment was followed. Fish were fed three times daily by at satiation. This research was result survival rate 100%; 100%; 100%; 96,29%; and 100% (P>0,05). Specific growth rate 5,196%; 5,212%; 6,596%; 5,35%; and 5,101% (P>0,05). Total length of Pangas catfish fry was significanly affected 1,451 cm; 1,518 cm; 1,964 cm; 1,71 cm; 1,546 cm (P<0,05). Quality of environment appears in optimal range during the conduct experiment. Using lime of CaO in 4‰ salinity medium suggested to choose 40 mg/ℓ concentration of CaO for best result.
