Results showed that insignificant (P 0.05) differences in final weight but significant (P≤ 0.05) differences in weight gain, daily gain and SGR to fish cultured in pond of lake Qarun water. But Egyptian sole cultured in low salinity water (5ppt) don’t less much and in the same range this indicated that possibility of cultured Egyptian sole in low salinity water. These results was similar to weight gain, specific growth rate and condition factor were recorded in the same species by Yones and Abel-Hakim (2011), Bonaldo et al. (2006), Rudea-Jasso et al. (2004) and Silva et al. (2010) when cultured this species and note that sole fish growth rate is different from other fish deployed in Egypt, such as tilapia. The HIS is often used as an indicators of condition and nutritional status of fish. Table (5).
