| dc.description.abstract | One of the abiotic factors that affects the growth and the survival of crabs is pH. The optimum pH media will give maximum impact on mangrove crabs because it is related with the osmoregulation process. This study aimed to examine the effect of pH on the survival rate (SR) and spesific growth rate (SGR) of Mangrove Crab (Scylla serrata) through the reaction of physiological condition. This study consisted of the treatments with the pH medium 5, pH medium 6, pH medium 7, and pH medium 8. The crab’smaintenance in different pH gave a significant effect (p < 0.05) on the survival rate of the crabs. The pH treatments also gave a significant effect (p < 0.05) on the Spesific Growth Rate (SGR) of the crabs. The low level of crab’s stress at pH 7 was described by the total value of high hemocyte and the high osmotic load so that the pH 7 was the optimum condition for the crabs. | en |
