The gobiidae, $Tridentiger$ $trigonocephalus$, $Chasmichtthys$ $dolichognathus$ and $Favonigobius$ $gymnauchen$ were reared for 4 weeks under 0~33.6‰ salinity conditions to examine the effects of various salinity on its survival and growth. Survival rate of $C.$ $dolichognathus$ and $F.$ $gymnauchen$ were significantly declined below 3.4‰ and 0‰, respectively. Growth rate of $T.$ $trigonocephalus$ was significantly reduced 0‰ salinity. Growth rate of $C.$ $dolichognathus$ and $F.$ $gymnauchen$ exposed to ${geq}$13.4‰ and ${geq}$6.7‰ were significantly higher than those of gobiidae exposed to below ${leq}$10.1‰ and ${leq}$3.4‰ salinity, respectively. This study reveled that low salinity (${leq}$3.4‰) reduced survival and growth rates of the 3 gobiidae suggesting potential influence on the natural mortality of gobiidae in the coastal areas.
