At the end of the 84-day experimental period, fish reared at 4 psu Accepted 15 October 2008 displayed shorter mean fork length, lower mean body weight, lower specific growth rate and higher food conversion efficiency than fish reared at 10 or 40 psu. The effect of salinity on growth performance was also Keywords: Shi drum
