The values are means SD (n=10) of triplicate groups. In each row the means with the same superscript letter are not significantly different (P > 0.05). Abbreviation, SL: standard length; BW: body weight; GRL (growth rate for standard length; %): (final mean SL-initial mean SL)×100/initial mean SL; GRW (growth rate for BW; %): (final mean BW-initial mean BW)×100/initial mean BW; CF: condition factor=un-gutted BW×100/standard length; GW: gutted body weight; VW: viscera weight; VI: viscera index=(viscera weight/GW)×100; DP: dressing percentage=(GW/un-gutted BW)×100; Ratio 1: fed group/initial group; Ratio 2: starved group/initial group; Ratio 3: fed group/starved group.
