Abstract

Global demand for seaweed continues to increase, encouraging Indonesia as a major producer to optimise cultivation areas in a sustainable manner. The Terujung coastal area, located within Saleh Bay, has long been used as a location for seaweed cultivation, but has not been scientifically evaluated in terms of aquatic suitability and carrying capacity. This study aimed to assess the level of suitability and environmental capacity of the area to support the sustainable cultivation of Eucheuma sp. in a sustainable manner. Analyses were conducted using a Geographic Information System (GIS)-based spatial approach and evaluation of water physico-chemical parameters and other supporting factors. Results showed that of the total area of 459,576 hectares, approximately 22.92% was classified as suitable, 58,09% as conditionally suitable, and 18.99% as unsuitable. The calculation of carrying capacity shows that only 89,35 hectares of area can be optimally utilized, with a maximum capacity of 178 longline units. This study provides a scientific basis for aquaculture zoning planning based on environmental suitability in the Terujung Coastal water.

Abstract

The southwest coast of Madagascar is home to small-scale Coral Reef Fisheries (CRFs), a vital activity for livelihoods and the local economy of the fishermen community. Understanding all about the components of this CRFs, the nature of their interactions and the resulting outcomes is crucial for designing policies that promote equitable and sustainable fisheries. This research aims to apply the Social-Ecological Systems (SES) framework and network analysis to assess the SES structure and the characteristics of Ranobe Bay CRFs, Madagascar. This research was carried out from September to October 2024, requiring primary data from field observations, interviews with respondents, and secondary data from literature studies. The Socio-Ecological Network Analysis (SENA) was used to analyze the connectivity of the CRFs in this region. The research findings of the SENA results showed that this fishery is heavily centered around the fishermen's community: the Masikoro and the Vezo as the main actors of this activity. Nevertheless, according to the cluster value analysis, the findings highlight a high number of clusters showcasing a low connectivity and less compact SES structure. Ranobe Bay's CRFs' sustainability depends on fishermen's central connectivity within the network, which can be strengthened through improved policies and management to ensure effective governance.
