of the experiment, whereas batch weighing per pool was
carried out once every 2 weeks to monitor growth performance
in terms of weight gain ratio alongside measuring
feed consumption. At the end of the experiment after
12 weeks, surviving fishes were randomly grouped into
three per tank and used to determine body indices and
carcass proximate composition.
Specific growth rate (SGR) {[(loge final body weight -
loge initial body weight)/time] 9 100}, food conversion
ratio (dry food intake/live weight gain), protein efficiency
ratio (PER) (live weight gain/protein intake), average daily
gain (growth/experiment duration), survival rate [(initial
no. of fishes/final no. fishes) 9 100] and weight gain (%)
[{(final weight - initial weight)/initial weight} 9 100].
Variations in weight gain (%), SGR, FCR, PER after
feeding of the test diets were analyzed by one-way
ANOVA and Tukey’s multiple range test and their mean
differences by least significant differences (LSD).
