Abstract:
This study was conducted to test the rejection percentage of the three species of
fungiid coral specially Fungia fungites (4n), Fungia scruposa (3n) and Fungia
repanda (3n) with artificial feed with containing 7 % (w/v) chitosan. A high
percentage of total rejected chitosan bead (84.46% - 96.08%) was found. The
diameter of the rejected chitosan is much smaller compare to the fresh chitosan
diameter. Fungia fungites has highest rejection speed (8.259 mm.h-
1
) chitosan via the
gastrovascular canals, followed by Fungia repanda (7.160 mm.h-
1
) and Fungia
scruposa (6.677 mm.h-
1
). Histological examination of Fungiids show that under the
membrane and along the spetal of the Fungiids, there is a lot of the continuous
gastrovascular canals present. Those canals are believed to accommodate the
acquisition of food and also serve as a digestion place for food particles.
