THE RESPONSE OF ELL Anguilla bicolor bicolor AGAINST MEDIA WITH DIFFERENT SALINITIES
This study aimed to determine effect of different salinity level of culture media for the production performance (survival rate, biomass growth rate, food conversion ratio, blood glucose content, and oxygen consumption rate) of eel Anguilla bicolor bicolor. The experimental designed completely randomize design (CRD) with four treatments which was different salinity level of culture media (A, 0 g/L ; B, 2 g/L ; C, 4 g/L ; dan D, 6 g/L) and three replications. The eel with body weight average of 8,43±0.32 g/fish. The result of this study showed that treatment A was the best treatment (survival rate 100%; biomass growth rate 9.31 g/day; and food conversion ratio 1.2; blood glucose content 22,30 mg/dL; and oxygen consumption rate 1.12 mgO2/g/jam). Water quality during the study are within the range of optimal maintenance of eels (temperature 31.7‒32.9 oC; pH 7.6‒7.7; dissolved oxygen 5.4‒5.8 mg/L; alkalinity 31,2‒39,5 mg/L; nitrite 0.26‒0.52 mg/L; and ammonia 0.001 mg/L).
