Abstract

The Sawu Sea National Park (SSNP) is a critical marine conservation area that supports the sustainability of fish resources and the livelihoods of coastal communities in Rote Ndao Regency. This study aims to analyze the dynamics of fish resource utilization in the Traditional Sustainable Fisheries (TSF) sub-zone, examine actor networks and catch distribution, and identify potential conflicts and strategic issues in small-scale fisheries management. A mixed-methods approach was applied, including a quantitative survey, in-depth interviews, field observations, and spatial analysis using GIS. The findings reveal the presence of external fishers utilizing modern fishing gear within the TSF sub-zone, leading to increased exploitation pressure and rising conflict potential. Declines in CPUE, fish size, and the disappearance of particular species are early signs of overfishing. Overlapping fishing grounds among fleets exacerbate social tensions and threaten ecological sustainability. Strategic recommendations include enhanced monitoring, evidence-based adaptive zoning, participatory conflict resolution, habitat restoration, and incentives for eco-friendly fisheries. This study underscores the importance of participatory and collaborative governance approaches to ensure the sustainability of fish resources in conservation areas.

Abstract

In this study, as a data-poor fish stock assessment method CMSY was used to assess the current stock status of the Sword Prawn in Samboja Waters. A total of 13 years catch data (from 2012 to 2024) was used in the analysing process of study. Estimated CMSY model parameters with confidence intervals are as folloe: r=0.47 (0.29-0.7) year-1, k=14.9 (10.1-22) ton, MSY=1.75 (1.23-2.36) ton, B2024=4.2 (0.43-5.89) ton, BMSY=7.45 (5.05-11) ton, F2024=0.28 (0.2-2.71) year-1, FMSY=0.23 (0.14-0.38) year-1, B2024/BMSY=0.56 (0.05-0.79) and F2024/FMSY=1.18 (0.84-11.4). Our study has found that sword prawn population in Samboja waters has been decline due to overfishing since 2017. Until now, regulations regarding catch quotas have not been established or implemented. Therefore, it is recommended to create regulations related to catch quotas based on research findings and reduce fishing mortality to maintain populations and prevent further biomass decline.

Abstract

Belawan Ocean Fishing Port plays a strategic role in the capture fisheries management system in western Indonesia. The high intensity of port operational activities contributes to increasing waste generation, which may adversely affect environmental quality and fisheries sustainability. This study aimed to evaluate the operational waste management system at Belawan Ocean Fishing Port and to examine its implications for fisheries management. An exploratory descriptive approach supported by quantitative estimation was applied. Data were collected through field observations, semi structured interviews with ten key informants, and document analysis of relevant regulations and official reports. Waste generation was estimated based on the number of vessels landing daily and the average waste generated per vessel. The results indicate that operational waste at Belawan Ocean Fishing Port consists of solid waste, liquid waste, and hazardous waste. The estimated daily waste generation reached approximately ±800 kg of solid waste, ±2.5 m³ of liquid waste, and ±10 liters of hazardous waste. The existing waste management system has not been standardized, as reflected by the absence of waste segregation at the source, non-operational wastewater treatment facilities, and the lack of dedicated facilities for hazardous waste handling. In addition, stakeholder awareness and community participation in waste management remain limited. This study concludes that operational waste management at Belawan Ocean Fishing Port has not been fully integrated into fishing port governance. Strengthening infrastructure, institutional capacity, and participatory approaches is therefore essential to support sustainable fisheries management in the port area.

Abstract

A financial feasibility analysis in mariculture activities is necessary to ensure the business can provide economic benefits and operate sustainably. The Dampier Strait Conservation Area has the potential to develop seaweed and pearl oyster cultivation businesses. However, as a conservation area, its utilization must consider environmental carrying capacity. This study aims to assess the financial feasibility of seaweed and pearl oyster cultivation in the Dampier Strait Conservation Area as a basis for optimal, environmentally friendly business planning that provides economic benefits for the local community. Financial feasibility is measured using a cost-benefit analysis method. The first step is to determine the efficiency of component use and cost structure in the aquaculture business planning scheme. The results of the cost and benefit calculations are used to determine the capacity for developing the aquaculture business, which includes an assessment of several aspects of future investment. Based on the results of the cost-benefit analysis, the marine aquaculture business for both commodities is feasible for development, having met business feasibility requirements based on the comparison of cost and benefit values, the percentage of profit, the rate of return on assets, the difference and comparison between expenses and revenues, and the payback period. All stages of the analysis have been able to produce comprehensive results to achieve optimal and sustainable utilization of the area through the development of mariculture activities. This has taken into account the continuity between environmental potential and human demands for utilizing ecosystem services in an integrated manner.

Abstract

Small pelagic fish are the dominant commodity in the fishing sector in the waters of Banten, accounting for 51.3% of total production in 2023. However, limited access to technology means that conventional fishermen in this region still rely on experience and intuition to determine fishing locations, which results in unstable catch yields and inefficiencies in operational costs, time, and labor. This study is designed to analyze the performance of the K-Nearest Neighbors (KNN) algorithm in classifying the abundance of small pelagic fish during the eastern season in the waters of Banten. Two oceanographic parameters were used as predictors: Sea Surface Temperature (SST) and chlorophyll-a concentration, both of which serve as indicators of aquatic ecosystem productivity. Secondary data were sourced from Aqua MODIS satellite imagery spanning the years 2021–2025, which were subsequently processed and integrated via the Kaggle and Google Colab platforms. The final dataset comprises 3,382 data points divided into two classes: potential and non-potential. Model testing was conducted by varying the K value (3, 5, 7, and 9) and the data split ratio (60:40, 70:30, and 80:20), using Euclidean Distance and the Confusion Matrix as performance evaluation metrics. The model with a configuration of K=7 and a 70:30 split ratio proved to yield the best performance, characterized by an accuracy of 95.66% and proportional precision, recall, and F1-score values across both classes. Permutation Feature Importance analysis indicates that chlorophyll-a contributes dominantly at 25.66%, while the recorded influence of SPL is 23.58%. These results confirm the superiority of the KNN algorithm in classifying small pelagic fish in the waters of Banten.

Abstract

Transportation of fish fingerlings is an important stage in aquaculture activities because it affects the success of fingerlings distribution. One of the factors influencing transportation success is stocking density during transportation. This study aimed to determine the effect of different stocking densities on the mortality of Nile tilapia (Oreochromis niloticus) fingerlings (3-5 cm) in a closed wet transportation system and determine the stocking density resulting in the lowest mortality rate. This study used an experimental method with a Completely Randomized Design (CRD) consisting of four treatments: A (100 fish/5 L), B (120 fish/5 L), C (150 fish/5 L), and D (200 fish/5 L) with six replications. Transportation was conducted for four hours with a water-to-oxygen ratio of 1:3. Parameters observed included mortality, survival rate, temperature, and pH. The results showed that stocking density affected the mortality of Nile tilapia fingerlings. The lowest mortality was observed in treatment A (1.83%), while the highest mortality was found in treatment D (7.83%). A density of 100 fish/5 L provided the best condition for minimizing mortality during transportation.
