Abstract

Growth and survival of juvenile marble goby (0. marmoratus) were determined at salinities of 0, 10, 20 and 30 ppt. Two similar experiments were conducted. 25 juvenile 0. marmoratus, 100 days after hatching (d AH) with mean. initial body weight, BW of 0.269±0.01S g and total length, TL of 29.9S±O.77 mm (experiment 1); 120 d AH with mean initial BW of 0.334±0.036 g and TL of 32.17±1.07 mm (experiment 2) were exposed these four salinities treatments with triplicates for 20 days in 7 -titres plastic aquarium. Juvenile 0. marmoratus were able to survie in 0 and lO ppt treatments with 100% survival rate, where no mortality was found throughout the experiments period. Survival rate in 20 ppt was 94.0±1.7% with no significant difference (P>0.05) compared to those in 0 and 10 ppt. However, survival rate in 30 ppt (77.3±5.2%) was significantly lower (P<0.05) to the other treatments. Fish reared at 0 ppt had a specific growth rate of 2.56±0.17 %/day in BW and 0.72±0.07 %/day in TL, a rate significantly higher (P<0.05) only to those fish reared at 30 ppt (l.l3±O.l4 5 %/day in BW and 0.33±O.03 %/day in TL). The study recommends that 0 ppt is the most suitable salinity to culture juvenile 0. marmoratus for better survival and growth.
