Abstract

Sandfish (Holothuria scabra) is one of endangered species, which has high economical value but has not been commonly cultivated. One factor that affects the success of sandfish culture is survival of larvae during attachment phase . In this phase the larvae of H. scabra need a substrate as a place to live. This study investigated the effect of seagrass and macroalgae as the settlement substrates on the survival of H. scabra larvae. The experiment trial was conducted in UPT LPBIL LIPI Mataram using completely randomized design with five replications for each substrate treatment. The settlement substrates used were Ulva sp. (P1), Gracilaria gigas (P2), Enhalus acoroides (P3), and Eucheuma cottoni (P4). Surface area was 14x19 cm2 in each treatment. At the beginning of experiment trial, one thousand larvae were distributed into plastic tank containing 10 L seawater for each tank. After 13 days experimental period, the survival of H. scabra larvae showed significantly different among substrates treatment. The highest survival was achieved by E. acoroides (15.53±2.23%), and followed by Ulva sp. (5.07±0.74%), E. cottoni (2.57±0.25%), and G. gigas (1.96±0.17%).
