| The juvenile gobiidae, Tridentiger trigonocephatus were reared for 40 days under the salinity ranges between 0 and 33.6$ extperthousand$ to examine the effects of salinity on the survival, growth and oxygen consumption rates of the fish. Survival rates were significantly declined for the fish reared under 3.4$ extperthousand$, and daily growth rates were also reduced below 6.7$ extperthousand$ Body length and weight of gobiids reared below 6.7$ extperthousand$ were smaller than those reared above 13.4$ extperthousand$. Oxygen consumption rates in the salinity conditions $leq$ 10.1$ extperthousand$ were significantly reduced with decreasing salinity. This study reveled that low salinity reduced survival, growth and oxygen consumption rates of the juvenile gobiids suggesting potential influence on the natural mortality of Tridentiger trigonocephalus in the estuarine areas where experience the extreme salinity fluctuations in Korean waters. |
