SPONGE (Callyspongia sp., Callyspongia basilana, and Haliclona sp.) CULTURE WITH DIFFERENT INITIAL EXPLANT SIZES
Abstract: Sponge global demand
for industry and research needs far exceeds supply from the sea. Aquaculture is
considered as the only viable method that can supply sufficient and sustainable
quantities of sponges. Aquaculture method is also one of efforts to anticipate
and avoid the over-harvesting of sponges in nature. However, culture methods
need to be determined to provide the platform for commercial success. In this
study sponges (Callyspongia sp., Callyspongia basilana, and Haliclona sp.) were
successfully cultured by transplantation method using polyethylene net with the
initial explant sizes of 1 cm, 3 cm, and 5 cm. The result showed that the
sponge growth and survival rates were dependent on the species. Callyspongia
sp. and Callyspongia basilana gave the highest growth and survival rates on the
treatment 3 cm with the final explants length reached 12.20 ± 2.35 cm and 7.603
± 0.93 cm and survival rates reached 98.33% and 36.67%. In contrast, Haliclona
sp. had the highest growth (21.67 ± 0.25) and survival (95%) on treatment 5 cm.
Nevertheless, among the three species, treatment using 3 cm and 5 cm of initial
explant sizes did not show a significant difference. Therefore for the efficiency
of explants use, the best initial explant length for culturing the three
species of sponges is 3 cm.
