The Haruo Village is one of the villages situated in Central Maluku Regency. This village is one of the most populous villages that have the livelihood of being tuna fishermen. All the fishermen from this village are considered mostly small-scale fishermen. The study was conducted between July to September 2020 to assess the sustainability of small-scale tuna fishery and proposed sustainable management strategy. Rapfish analysis was used to analyze small-scale tuna sustainability status and DPSIR to proposed a sustainable management strategy. The result showed that fair trade gave benefit in terms of ecology, socio-economy, and institutional towards the small-scale tuna fisheries compared to non-fair trade in terms of the socio-economy aspect. The sustainable status of small-scale tuna fishery, in general, was considered sustain (74.52%) for fair trade approach and less sustain (51.72%) for non-fair trade. The institutional dimension from non-fair trade tuna fishery was the lowest one (24.68%) and was considered unsustain. Based on the DPSIR approach, eight strategies management plans were proposed for sustainable management of small-scale tuna fishery in Haruo Village. The strategy can be applied at Driver (D), Pressure (P), State (S), and Impact (I) level.

Mud crab Scylla serrata of Kotania Bay and Pelita Jaya Bay of Western Seram District, has been harvested by local fishermen for more than 25 years. The mud crab has high economic value, and there is always a market for this fishery. The economic dependence of the fishermen forces them to harvest this resource extensively. No existing management strategy and extensive exploitation leads to unsustainable conditions of this fishery. With inadequate data condition, the Driver-Pressure-State-Impact-Response (DPSIR) model constructs an ecological, social-economy, and institutional conceptual model framework for sustainable management of this fishery. The driving force (D) in this fishery comes from the local fishers harvesting the mud crab. The two most sensitive attributes that affected mud crab sustainability from Rapfish analysis were used as state-level of DPSIR methodology. The result shows that the most sensitive variables from ecological, socio-economy, and institution were: caught before maturity, mud crab size, consumer attitude towards sustainability, just management, government quality, and monitoring and reporting, respectively. It was concluded that this conceptual model allows a better understanding of how the mud crab S. serrata system works and management actions taken at different system components. This conceptual model framework can be a useful tool to incorporate the participation of stakeholders, managers, and scientists in the process of a sustainable management plan.

The coastal community especially women and children in Maluku usually utilize marine organisms when low tide or locally known as bameti. The gear use in this activity is simple such as spear, knife, and digger, or even by using bare hand. One of the target marine organisms is the conch (Strombus spp) that lives in the coastal area on a seagrass bed. This research was conducted to study the community structure of Strombus spp in Haria coastal waters, Central Maluku, Indonesia in February 2020. The sample was collected by using transect linear quadrate with the size of quadrate is 1൱m2. As many as 297 individuals of Strombus spp were collected during the study which consists of five species namely Strombus labiatus, S. mutabilis, S. urceus, S. gibberulus, and S. luhuanus. S. labiatus has the highest density and occurrence frequency while the lowest belongs to S. luhuanus. Based on ecological indexes, Strombus spp in the area have high diversity and high evenness with low dominance.
