ABSTRACT One of the abiotic factors that affects the growth and the survival of crabs is salinity. The optimum salinity media will give maximum impact on mangrove crab Scylla serrata due to the osmoregulation process. This study aimed to examine the effect of salinity on the survival rate (SR) and spesific growth rate (SGR) of mangrove crab through the reaction of physiological condition. The treatments were rearing mangrove crab at the salinity medium of 15 ppt (A), 20 ppt (B), 25 ppt (C), and 30 ppt (D). Result showed that different salinity performed a significant effect (P<0.05) on the survival rate and specific growth rate of the crabs. The low level of stress, shown by the high value of total hemocyte and the low osmotic pressure, has made salinity of 25 ppt was the optimum condition for the mangrove crab rearing. Keywords: salinity, survival, specific growth rate, mangrove crab ABSTRAK Salah satu faktor abiotik yang memengaruhi pertumbuhan dan kelangsungan hidup kepiting adalah salinitas. Salinitas media optimum akan memberikan efek yang maksimal pada kepiting bakau Scylla serrata sehubungan dengan proses osmoregulasi tubuhnya.

ABSTRACT Increasing of freshwater tambaqui Colossoma macropomum demand makes the farmers increase the production of the consumption fish and seed. Acceleration of the production cycle can increase total production level, and reduce the level of osmotic work can be used to improve fish growth. This study aimed to analyze the effect of the addition of calcium carbonate (CaCO3) in the saline medium of 3 g/L on the growth of freshwater tambaqui juvenile. Tambaqui used has a body length of 1.93 ± 0.1 cm and weight of 0.26 ± 0.03 g. The experiment used 15 units of aquarium at size of 30×15×25 cm3 and filled with 9 L of saline water, then added lime CaCO3 according to treatment. The treatments were control (0 mg/L CaCO3), A (50 mg/L CaCO3), B (100 mg/L CaCO3), C (150 mg/L CaCO3), and D (200 mg/L CaCO3). The study was conducted for 30 days of maintenance. Fishes were fed on bloodworms ad libitum or provided three times a day. The results showed that survival, daily growth rate, and absolute length growth of the CaCO3 treatments significantly higher (P<0.05) that that of control. Furthermore, survival, daily growth rate, and absolute length growth among the CaCO3 treatments were the same. Thus, addition CaCO3 of 50 mg/L saline water of 3 g/L can be applied to increase culture performance of freshwater tambaqui. Keywords: freshwater tambaqui, CaCO3, salinity ABSTRAK Permintaan terhadap ikan bawal air tawar Colossoma macropomum yang semakin meningkat membuat pembudidaya menambah produksi ikan konsumsi dan benih.
