This research aimed to know the length-weight relationship, condition factor, and otolith shape of marble goby ( Oxyeleotris marmorata  Blkr.) at Sermo Reservoir Yogyakarta. In total 211 samples (95 males and 116 females) were collected using gillnet and folded trap (bubu). Each sample was observed for sex determination, and then measured its total length, body weight, and otoliths diameter. The data were analyzed to determine the length and weight distribution, length-weight relationship, condition factor, and length-otolith diameter relationship. The result showed that the total length of the male was ranged 12.0-38.2 cm and female was ranged 12.2-44.5 cm. The weight of the male was ranged 21.0-704.8 g and female was ranged 21.1-1593.7 g. Both male and female have positive allometric growth with the equation W=0.0056L 3.2894  for male and W=0.0051L 3.311  for female. Condition factor was ranged 0.787-1.313 for male and 0.800-1.379 for female, and the majority of fish has a good condition (Kn ≥0.95 more than 50%). The shape of otolith edge was sinuate surrounded with regular wave-like curves, the diameter was increased in line with increasing of total body length by an equation of Y=0.2335+0.0248X (r=0.938).
