EFFECT OF SALINITY ACCLIMATION ON FOOD INTAKE, DIGESTIBILITY AND EVACUATION RATE IN LIZA ABU JUVENILES

Abstract

The results obtained for the juveniles of Liza abu showed that in high salinity there was a decrease in food intake (1.88%) compared to low salinity (7g/l) and tap water (1.5g/l). Also the total digestibility decreased 10% with increasing salinity from1.5 to 15 7g/l as a result of increasing the evacuation rate, where values reached 88.39% and 90.3% from total faces weight in salinity 7 and 15 g/l respectively after 18 hrs.
