“…That confirms that the sandy substrates of the West Java Coast are suitable and potentially support brittle star conservation practices. Despite its current geographical distribution, the records of O. echinata in this study were in agreement with the results from Paujiah et al (2018) and a recent study by Bahtiar et al (2020) that confirm the presence of O. echinata within Indonesia's tropical waters. Similar to O. echinata, O. aethiops is present within Indonesia's tropical waters with a density of 0.045 indv/m 2 , as confirmed by Katili (2011) In this study, the sandy substrates of the Sancang Coasts were the point of interest to be recommended for brittle star-suitable habitats.…”

“…Here, O. scolopendrina was a brittle star species that is very common and abundant in comparison to other brittle star species. This condition is in agreement with the results from nearby coastal in Rancabuya Coast, West Java (Paujiah et al 2018). In Rancabuaya, O. scolopendrina was present in every location, including sandy substrates with high numbers.…”

Abstract. Suprapto PK, Husna IR, Meylani V, Basukriadi A, Wibowo AA, Nurdin E. 2022. Spatial models of suitable sandy substrates for brittle star community conservation in Sancang Coast, West Java, Indonesia. Indo Pac J Ocean Life 6: 87-93. The brittle star is known as one of the echinoids with the largest members. Currently, brittle star species are threatened due to harvests for fulfilling decorative species demands in aquariums. This study aims to determine suitable sandy substrates for the brittle star community in Sancang Coast, West Java, Indonesia, in three representative stations. Brittle star presences and environmental variables were surveyed using belt transect methods, and sandy substrate suitability was determined using scoring and an interpolation method aided by GIS. Results show three species belong to the Ophiocomidae, with Ophiocoma scolopendrina (Lamarck, 1816) (brittle lagoon star) being the most abundant. About 394,631 m2 of sandy substrates were available, and an estimated 47.52% is considered very suitable for brittle stars. Most suitable sandy substrates were located on the West side, characterized by low water temperature, high salinity, and alkaline water. In contrast, less suitable sandy substrates were located on the coast's east side, characterized by high water temperature, low salinity, and acidic water. To conclude, this research has identified which parts of the Sancang Coast should be prioritized to conserve brittle stars.
