Incorporating the Ecological, Socio-economic and Institutional Conceptual Model Framework for Sustainable Management of Small-scale Mud Crab (Scylla serrata) Fishery in Western Seram Regency, Indonesia

Abstract

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 Local Wisdom Knowledge Applied in The management of Coastal Resources at Ilili Village, Western Seram District, Indonesia

“…The most sensitive attribute (Leverage analysis) from Rapfish analysis that affect the sustainability of customary law will be used to construct a management strategy. The Driver-Pressure-State-Impact-Response (DPSIR) conceptual model framework [23,24,25] was used to propose sustainable management of the customary law. In the development of an acceptable and workable resource management policy, consideration must be given to the preferences of stakeholders within the system.…”

Population parameters and sustainable status of lompa fish Thryssa baelama (Forsskal, 1775) manage through sasi approach at Haruku Village

“…This approach has been indicated as a helpful approach in analyzing human and natural systems (Gari et al, 2015;Martin et al, 2018;Mazumder et al, 2016). Since there Fisheries and Aquatic Sciences were 36 variables used in sustainability analysis, to simplify the connectivity interaction among variables in the conceptual model framework, only one variable from each dimension with the highest sensitivity was used to construct the model (Natan et al, 2021). The conceptual model produced was then used as a management strategy for the sustainability of lompa fish.…”
