Abstract

Regional development with a Minapolitan concept is part of the marine and fisheries industrialization policy strategy which aims to realize accelerated increases in the income of cultivators, fishermen, processors, and marketers by integrating upstream and downstream production systems to increase the scale and quality of production, productivity, competitiveness and added value for sustainable marine and fisheries resources. The Minapolitan program is designed to increase the competitiveness of fisheries commodities which is then targeted to increase regional competitiveness and reduce the gap between urban and rural areas. This activity is intended to formulate a development center for the Minapolitan area of ​​Wajo District which will become the basis for preparing technical work plans for related agencies. Based on field results, it was found that the marine and fisheries resource potential of Wajo District was mapped into two resource potential zones, namely (1) the coastal subdistrict area (Bola, Takkalalla, Sajoanging, Penrang, Keera and Pitumpanua subdistricts) which is directly connected to the waters of Bone Gulf for the utilization of potential resources of capture fisheries and aquaculture (marine cultivation and pond cultivation); and inland fisheries areas, especially in the Tempe lake area (Sabangparu, Tempe, Tanasitolo and Belawa subdistricts). Utilization of the potential of the coastal areas of the District of Wajo, with its characteristics of an open water area directly bordering Gulf of Bone, has more potential for the development of capture fisheries, marine aquaculture, and brackish/pond cultivation with the superior commodities of seaweed and mangrove crabs as well as coastal ecotourism. Meanwhile, the Tempe Lake area is more geared towards fishing, cultivating freshwater fish and limited area management for ecotourism activities.

Abstract

The exploitation level of fish resources should be based on effectiveness, efficiency and business sustainability. One of the efforts to implement these three aspects is to understand the seasonal pattern or the best time to catch the fish target. The aim of this research was to estimate the pattern of the anchovy fishing season based on production data landed at PPI Paotere Makassar, South Sulawesi. Data is collected from the PPI and analyzed using the moving average techniques. Results showed that the seasonal pattern of anchovy fishing is estimated to increase in the transition season to the eastern season (IMP > 100%) and reach a peak in September (IMP = 134.74%). Descriptively, the fishing season, especially the peak season, was thought to occur because these fish are probably associated with optimum conditions for oceanographic parameters such as sea surface temperature, chlorophyll-a concentrations and surface current conditions. Information on anchovy fishing season patterns is really needed by marine fisheries managers, both government and private, in managing efforts to exploit fish resources wisely and sustainably.

Abstract

Chlorophyll-a concentration is a critical indicator of marine ecosystem health, reflecting primary productivity and potential ecological changes. However, the occurrence of outlier data in the Banda Sea and its surroundings has not been sufficiently studied. This study aims to investigate the dynamics of chlorophyll-a concentration outliers in the Banda Sea, focusing on their spatial and temporal patterns from 2010 to 2022. Data were acquired from MODIS satellite imagery and analyzed using R Studio for time series decomposition, while spatial patterns were explored with ArcGIS 10.8 and Google Maps to pinpoint key hotspots of outlier activity. The findings reveal fluctuating chlorophyll-a outliers with extreme concentrations ranging from 14.39 to 81 mg·m⁻³. Temporally, these outliers are predominantly observed in the western Banda Sea during January to March and December, while in the eastern Banda Sea they occur from June to September. Spatially, these anomalies are concentrated in areas of significant human activity, particularly in Tolo Bay, suggesting a potential link between anthropogenic influences and ecological disruptions. Field monitoring in areas with persistent outliers is strongly recommended to verify actual conditions and assess their ecological impacts. While chlorophyll-a plays a vital role in marine productivity, excessive concentrations can disrupt ecosystems, potentially leading to harmful algal blooms or hypoxic conditions. This study underscores the importance of integrating remote sensing, field validation, and spatial analysis to effectively monitor and manage these anomalies. Enhanced understanding of these dynamics is critical for informed decision-making and sustainable marine management practices in the Banda Sea.

Abstract

This study models the spatial distribution of yellowfin tuna (YFT) in the Banda Sea using the MaxEnt approach, addressing critical questions about its predictive capability, the influence of environmental variables such as sea surface temperature (SST) and chlorophyll-a concentration, and temporal patterns. MaxEnt was chosen for its ability to predict potential distribution areas based on presence data and environmental factors. Data utilized include fish catch records obtained from the fishing logbook of the Ministry of Marine Affairs and Fisheries of the Republic of Indonesia, chlorophyll-a concentration, and SST data sourced from ocean color satellite observations. Model performance was evaluated using the Area Under the Curve (AUC) metric. Study results reveal that significant spatial and temporal variations in YFT distribution are influenced by oceanographic factors, with the model performing best in July (AUC 0.72) and lowest in April, September, and December (AUC ~0.60). SST was the dominant variable in November (82.35%), while chlorophyll-a had the highest contribution in April (83.02%). These findings highlight the dynamic link between tuna distribution and environmental conditions. The spatial maps offer insights for optimizing fishing practices, reducing pressure on overexploited stocks, and supporting sustainable fisheries management through data-driven approaches like MaxEnt. However, the MaxEnt model has limitations such as sensitivity to multicollinearity, overfitting, and low transferability. Future research could enhance accuracy and robustness by using advanced methods like Spatial Maxent, Monte Carlo Variable Selection, or ensemble modeling to support adaptive fisheries management.
