This study was investigated to examine the therapeutic effect of Hibiscus rosa-sinensis
in protecting fish against important ecological disease. Disease resistance to
experimental infection with Aeromonas hydrophila was also assessed. The fish that
were used is juvenile Nile tilapia Oreochromis niloticus. The fish were feed
commercially with artificial diet twice a day that supplemented with 3 treatment. There
was 3 replicates each treatment. Each diet was had 3 different concentration of
Hibiscus rosa-sinensis crude extract in commercial food, which is 0% for control, 25%,
50% and 100%, will be use and each concentration are used to feed triplicate groups
of tilapia (Oreochromis niloticus) juvenile for 10 days. The present result indicated
that supplementation with 50% and 100% of Hibiscus rosa-sinensis crude extract
shows less mortality rate while supplementation with 25% of Hibiscus rosa-sinensis
crude extract shows the highest mortality rates with 10 fish died recorded in 5 days.
Based on the present performances, the results of the current study indicated that the
Hibiscus rosa-sinensis crude extract were effective against important ecological
disease that caused by Aeromonas hydrophila
