ABSTRACT
Estimation oflength-weight relationship and conditionfactor, were done
for Solea aegyptiaca Chabanaud, 1927 collected from Abu-Kir off
Alexandria and Lake Qarun during the period of1993-1994. This study is
carried out to determine the suitability ofenvironmental conditions in the
Mediterranean Sea and Lake Qarun for this species.
The computed length-weight relationships for Solea aegyptiaca in both
areas showed that, for aI/lengths, the calculated weights are heavier from
Lake Qarun than those from Abu-Kir Bay and highly significant difference
is observed between the two habitats at 1% level.
The mean· value ofcondition factor (K) was found to be higher in Solea
aegyptiaca from Lake Qarun than those from Abu-Kir Bay and this
variation is statistically highly significant at 1% level.
