Abstract: The study on the growth characteristics of Oxyeleotris marmoratus under artificial breeding showed that after two months growth, the body length (L) of O. marmoratus increased from （17.36±0.99）cm to （19.05±0.57）cm, and its body mass (W) increased from （139.13±12.90）g to （205.50±15.78）g. Different duration of breeding had no significant effects on feeding ratio (FR) (P>0.05), but affected specific growth rate (SGR), feed conversion ratio (FCR), and growth efficiency (GE) significantly (P<0.05). The body length had a linear relationship with breeding duration, and the body mass had an exponential growth with the duration. There was an exponential relationship between body length and body mass, and the exponential value b within different durations was all close to 3, suggesting an isometric growth between the body length and body mass of O. marmoratus.
