| Abstract: | 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. Kualitas dan kuantitas benih merupakan salah satu faktor yang penting dalam usaha budidaya ikan. Dewasa ini usaha-usaha untuk meningkatkan kualitas dan kuantitas benih ikan patin telah banyak dilakukan diantaranya dengan memperbaiki kualitas lingkungan. Pertumbuhan ikan dipengaruhi oleh faktor internal dan eksternal. Faktor internal merupakan faktor yang susah dikontrol dan berhubungan dengan ikan itu sendiri seperti seks, keturunan, ketahanan terhadap parasit dan penyakit sedangkan faktor eksternal merupakan faktor yang berhubungan dengan lingkungan media hidup ikan dan mudah dikontrol yang meliputi kemampuan dalam pemanfaatan pakan serta sifat fisika kimia air. Salah satu faktor lingkungan yang berperan dalam pertumbuhan adalah salinitas. Salinitas berpengaruh terhadap pertumbuhan karena salinitas mempunyai tekanan osmotik yang dapat menyebabkan perubahan aktivitas fisiologi ikan. Selain salinitas, kalsium juga memiliki peranan penting dalam proses osmoregulasi yang terjadi dalam tubuh ikan dengan lingkungan, serta penting untuk pembentukan tulang dan pengaturan permeabilitas dinding sel. |
