The species composition, abundance and distribution of sea cucumbers in the intertidal zone of Cab-ilan Island, Dinagat, Dinagat Islands, Philippines were assessed using a transect quadrat method, with a size of 1x1 meter, on a transect line with a length of 80 meters. Sampling was done at the two identified stations in three replicates. A total of 10 species were found namely Holothuria scabra, H. leucospilota, H. fuscopunctata, H. hilla, H. fuscocinerea, H. pervicax, Actinopyga echinites, A. mauritiana, A. miliaris and Bohadschia marmorata. The most abundant species found were the Holothuria scabra, H. hilla and Actinopyga echinites. A. echinites was the only common species found in both stations. Results revealed that there was no significant difference in salinity between stations (P>0.05). However, species diversity, temperature and pH differ significantly in Cab-ilan Islands (P<0.05). The Non-metric multi-dimensional scaling (nMDS) based on square-root transformed abundance data showed that a clear segregation of samples between two stations. Cluster analysis also revealed that there is no close relationship of the samples between Station 1 and Station 2. SIMPER analysis also showed that there was a high dissimilarity percentage in both stations. Some species of sea cucumbers and their distribution were influenced by physico-chemical parameters such as pH and temperature.

“…revealed that the number of sea cucumbers found was likely to be higher if the sampling was held at night (Personal communication; (Wisesa et al, 2018). It was stated by (Tanduyan et al, 2013) that H. scabra had a frequency found twice as much at night compared to daytime.…”

HighlightEight species of sea cucumber was found in four intertidal location in Southeast Moluccas and Tual watersHolothuria atra had the highest densitySea cucumber biodiversity in Southeast Moluccas and Tual waters categorized as lowLocal culture can be used for sustainability of sea cucumber resources management AbstractA study on the community structure of sea cucumber in Southeast Moluccas and Tual needs to be done due to the important role of sea cucumber in both ecologically and economically sustainability. This study aimed to investigate the community structure of sea cucumber in this region as one of the supporting information for the utilization and management of the resources. A survey was conducted by sweeping the target area, by walking and also snorkeling. The location where each sea cucumber found was marked using a GPS, the specimen was weighed, and some were preserved for species analysis. Water quality was measured at each location, while the substrate and vegetation were recorded. This study revealed different composition of species in the investigated area. As many as 8 species of sea cucumber were found, in which four were of genus Holothuria, three were of genus Stichopus and the rest were of genus Bohadschia. Species H. atra has the highest density. In general, the diversity index was relatively low (< 2), the evenness index was 0-81 indicating that the community was depressed. Certain species dominated at most of the investigated sites (0.50-1), and a low margalef index is 0-1.7. To conclude, the community structure of sea cucumber in Tual and Southeast Moluccas was in a depressed condition.
