Holothurians have benefit both for economic and ecology. Economically, holothurians are source for protein and could be used for healing some diseases. Therefore, they have highly expensive both local and international scale. In addition, ecologically they are source for food and substrate fertilizer. Tatumbu Island is uninhabitant in Kotania Bay, West Seram and coverage by seagrass ecosystem. So, it would be suitable place for holothurians distribution. Nowadays, the demands for holothurians are still highly for export commodity. Consequently, the population would decrease in the future. The purpose of this study is to know the densit, potential and the utilization of holothurians in Tatumbu Island. Data were collected at three stations by using Belt Transect. To identify the utilization of holothurians, the interview was done by using questionnaire. Environmental parameters were measured in situ including temperature, salinity and potential of hydrogen (pH). The results showed that there were nine commercial species and other three species found. The density of three stations ranged from 0,0012-0,0353 ind.m-2 and the potential was 17187 individuals. The highest density and potential were represented by Stichopus horrens whilst the lowest density was represented by Actinopyga echinites. Generally, holothurians distribution on sandy substrate associated with seagrass. The utilization of holothurians is conducted daily and continues by fishers. The temperature, salinity and pH indicated that the waters of Tatumbu Island were suitable for sea cucumber growth.

People's awareness of the marine environment should be started by the student in Elementary School. The public service program was conducted to increase student knowledge of the marine environment and the fisheries resources and also to protect that. This program consists of giving a lecture, discussion, and evaluation to the student of SD Negeri 2 Oma, Haruku Island Regency, Central Maluku. The topics consist of the marine environment and the importance of this environment, types of the shore, marine mollusc resources (definition and clasification), economically important molluscs, marine Gastropoda which consumed by local people, and how to protect the marine environment and its resources. Based on the evaluation, student knowledge increased from <30% before socialization to >90% after socialization. It means that education processes for the elementary student about the problems of the marine environment and its resources increase significantly, and need more information on other marine resource.

Gastropoda diversities can be used as an ocean health index The higher the species diversity of marine gastropod s, the better the ocean environment. Recently, there is no publication on gastropod communities in the intertidal zone of Seri District, Ambon, Indonesia. The research on gastropoda communities was conducted in July 2023 at the intertidal zone of Seri district, Ambon. The objectives of the research were to identify the species of gastropods, to analyze its ecological density and abundance, and also to analyze gastropod diversity indices. Sampling was done at three sampling sites with simple random sampling method during low tide with applying sampling kuadrat about 5x5m. A total of 21 species of marine gastropod were found in this study which grouped into six ordo, 11 family and 16 genera. The higest number of species found in the ordo of Neogastropoda. Patelloida striata has the highest ecological density in station 1 and station 2 (7 individu.m-2 and 11 individu.m-2, respectively), whereas Patteloida saccarinoides and Nerita polita have the highest ecological density in station 2 (each has 8,47 individu.m-2). Shannon diversity index (H`) varied between 1,987 and 1,984. Pielou evenness index (J`) ranged from 0,656 to 0,903. Whereas Simpson dominance index (D) varied from 0,146 to 0,223. It can be concluded that gastropod species diversity in the intertidal zone of Seri District was categorized as low diversity, evenness index was moderate to higher, while there was no dominance species in the communities.
