Abstract

The effect of plant from 5 sources i.e. palm kernel cake, copra meal, corn, rice bran and cassava were
studied in sex-reversed red tilapia for digestibility coefficient and growth performance. For each feed
formula, 30% of each plant material was mixed with 70% basal feed. The feeds were given to sex-reversed
red tilapia, with weight ranging from 3.14-3.20 g stocked in 200-l glass aquaria with a closed recirculating
system. Each treatment comprised 4 replications. The experimental period was 6 weeks. The best results on
average body weight, weight gain, specific growth rate and digestibility coefficient were noted for the fish
group given the feed containing palm kernel cake, while the poorest result was obtained from the group fed
with rice bran. Fish groups given the feed with copra meal, corn and cassava showed results in descending
order.
