Abstract

Blue Swimming Crab (BSC) is an Indonesian fishery export commodity that has high economic value, with the largest BSC production in Indonesia in WPPNRI 712. Cirebon and Demak are the centers of BSC landing base in WPPNRI 712. Data and information on fishery characteristics are needed as a basis for arranging sustainable fishery management policies. This study aims to analyze variations in BSC fishery characteristics in the Cirebon and Demak districts. This study was conducted from August to September 2024 in both locations. Data collection was carried out using field observation and interview methods, and samples were taken using a purposive sampling method. The data analysis was carried out by comparing fisheries characteristics of two locations and evaluating compliance with applicable laws and regulations. The results of the study showed that there were variations in the characteristics of BSC fisheries in Cirebon and Demak, namely: boat, fishing gear, fishing grounds, catch composition, and socio-economic conditions of BSC fisheries. Fishers used traps, bottom gillnet, bottom otter boat trawl, and dregde (specifically in Cirebon) to catch BSC with boats 1-2 GT size. Traps and bottom gillnets are allowed fishing gear operating in Indonesian waters, while bottom otter boat trawl and dredge, as non-permitted gears, have a detrimental impact on fish resources and its environment. The BSC is the main target of traps and bottom gillnets, while these are as bycatch for bottom otter boat trawl and dredge. Demak fishers sell fresh BSC, while in Cirebon, they sell BSC meat and fresh. Key words: blue swimming crab, Cirebon, Demak, fisheries characteristics, WPPNRI 712

Abstract

Mimi, a term for horseshoe crabs (Limulidae), often constitutes an unintended bycatch in blue swimming crab (BSC) fisheries employing bottom gillnet fishing gear. Three horseshoe species found in Indonesia have been designated as ETP species. This research aims to test the efficacy of red LED Cree lights in BSC bottom gillnet fisheries to reduce horseshoe crabs bycatch. The experimental fishing approach was employed in the waters of Ambulu Village, Cirebon Regency, with 17 trips as replication. Two sets of gillnets, as control and treatment (equipped with LED lights), respectively, were utilized in the study. Data collected were the number of species and individuals of targeted species (BSC) and horseshoe crab as bycatch resulting from the BSC gillnet operations in both control and treatment nets. A descriptive analysis was used for catch composition. Statistical analyses, including paired sample t-tests and Wilcoxon tests, were conducted on the horseshoe crab bycatch and BSC catch data to test differences between the control and treatment nets. The most abundant catch consisted of crab (Actaeodes tomentosus), with 82 individuals captured in the treatment nets and 87 in the control nets. Blue swimming crab (Portunus pelagicus) caught 76 and 53 individuals in the treatment and control nets, respectively. The bycatch of horseshoe crabs (Limulidae) in the treatment and control nets of 10 and 27 individuals, respectively. The analysis revealed that the BSC catch in the treatment nets did not significantly differ from that in the control nets. Conversely, a significant difference was observed in the horseshoe bycatch between the treatment and control nets. Incorporating red LED Cree lights resulted in a 35.79% increase in the BSC catch and a 62.96% reduction in the horseshoe bycatch.

Abstract

Graphical Abstract Highlight Research 1. Integration of multi-variable oceanographic parameters for mapping fishing areas. 2. Spatial-temporal dynamics based on changes in oceanographic parameters. 3. Development of upwelling index-based fishing area detection methods. 4. Optimization of fishermen's operations through the prediction of potential locations.   Abstract Sustainable management of scad stocks (Decapterus sp.) in FMA 573 necessitates integrating satellite-based oceanographic monitoring to identify distribution zones amid complex aquatic dynamics. This study integrates satellite imagery, descriptive analysis, and spatial modeling to map oceanographic parameters and identify fish distribution zones, aimed at enhancing the monitoring and sustainable management of scad stocks in FMA 573. The research combines satellite-based oceanographic monitoring with CPUE analysis and spatial modeling to determine fish distribution based on environmental suitability. Results indicate that oceanographic conditions fluctuate seasonally, with warm waters dominating the West Monsoon and Transition-1, while higher salinity and Chl-a concentrations characterize the later seasons. Habitat suitability modeling reveals that scad potential is primarily concentrated in coastal areas during the West Monsoon and Transition-1. The spatial distribution of the scad in FMA 573 shows a preference for coastal areas with a strong dependence on oceanographic dynamics. This spatial shift between coastal and offshore zones is primarily driven by the seasonal expansion of optimal SST and Chl-a concentrations, which alter the boundaries of suitable habitats. However, a spatial-temporal discrepancy exists: while environmental suitability peaks early in the year, industrial landing data shows fishing activity concentrated offshore, peak during Transition-2. This mismatch suggests that existing catch data reflects industrial operational habits rather than the full biological potential of nearshore areas, highlighting the need for supplementary data from small-scale fishers to validate coastal PFZs. These findings provide a baseline for predictive catch modeling and seasonal spatial recommendations. Identifying the shift from coastal zones in the West Monsoon to offshore waters in Transition-1 allows for optimized fishing efforts, improved fuel efficiency, and more precise monitoring of fishing pressure.
