0.05). It was found that salinity does not affect significantly the condition factor of the individuals. Condition factor was ranging from 0.93 to 1.03 and there were no significant differences (P<0.05) between fish that had been subjected to different salinity treatments. Gonad somatic index (GSI) wassignificantly influenced by salinity (P>0.05). The GSI for both males and females have nearly the same fluctuation trends which reached to the maximum level at salinity of 40 ‰ for both sexes; 8.9 for female and 2.1 for male. The highestcoefficient "b" of length-weight relationship were 2.839, 2.847 for fishes at salinities 40 ‰ and 5 ‰, respectively they closed to 3 it is indicated that isometric growth. The gonad maturation of salinity 5‰ reached to ripe stage for male and yolk vesicle stage for female but it reached to ripe stage at salinity 40‰ for both sex. These resultssuggest that Liza carinata is a suitable candidate for low salinity brackish water aquaculture. This could lead to significant cost savings when rearing fish inland. ]]>

0.05), whereas F and M+F treatments recorded lower survival (P<0.05) in the second experiment. Fish production was comparable under feed (F) and manure (M) treatments (P>0.05) in experiment one, but was significantly (P<0.05) different in experiment two. The increment in gross fish production over the control was 103.22 and 119.99% in feed, 77.30 and 59.44% in manure and 162.34 and 175.08% in M+F treatments of the two experiments respectively. Carcass protein, fat and ash contents were significantly (P<0.05) higher in the three treatments as compared to the control.]]>
