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

The lack of data and information concerning the scad fishing grounds in that area restricts the efficiency of fish capture. This research aims to estimate the CPUE of the scad, map the spatial-temporal dynamics of sea surface temperature (SST) and chlorophyll a (Chl-a), and evaluate the SST and Chl-a relationship to scad catch rates in the Banda Sea. The SST and chl-a were obtained from Aqua MODIS satellite imagery over three years (2020-2022), while scad catch data were obtained from the Kendari Fishing Port. Bivariate correlation analysis was used to assess the relationship between SST, Chl-a, and scad catch rates. The results show a fluctuation trend in CPUE (2020-2022), with CPUE values ranging from 53.41 to 354.65kg/trip. The temporal distribution of SST values ranged from 26.91 to 29.42°C, while the Chl-a concentration ranged from 0.20 to 4.8mg/m³. Spatially, it was higher near the shore and lower offshore. A moderate negative correlation (r = -0.464) was observed between Chl-a and CPUE, while SST showed a weak positive correlation (r = 0.101) with the CPUE. This study recommends integrating field data and satellite imagery to accurately estimate the fishing grounds to improve efficiency and sustainable fisheries management in the Banda Sea.

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 the Potential Fishing Zone (PFZ), 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 preliminary suitability mapping and hypothesisgenerating spatial guidance. 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.

Abstract

The invasive suckermouth catfish (Pterygoplichthys spp.), native to South America, poses ecological threats in non-native freshwater systems. However, effective natural baits for its control remain understudied. This study evaluated the behavioral responses of three size classes (<10 cm, 25 cm, >35 cm) to two baits—Lumbricus rubellus (earthworm) and Loligo sp. (squid) and assessed bait durability via protein and fat leaching over 15 hours. Using 32 CCTV-monitored trials, significant ontogenetic differences were observed (p < 0.05): juveniles responded most actively (10 and 9 approaches), adults avoided earthworms but approached squid moderately (5 times), and larvae showed intermediate responses. Though earthworms induced a faster mean response time (20:19 min), it was not statistically different from squid (p = 0.79). Biochemical analysis revealed superior nutrient retention in L. rubellus (protein: 10.78%, lipid: 9.90%) compared to rapid leaching in squid. The findings suggest that L. rubellus is a highly effective bait for catfish due to its strong chemosensory attraction and nutrient stability, supporting size-specific baiting strategies for targeted management of this invasive species.

Abstract

Crab gillnet is a fishing gear intended for catching crabs that have the potential to cause Abandoned, Lost, and Discarded Fishing Gear (ALDFG). This research aims to estimate the potential for ALDFG and waste supplies from crab gillnet fisheries and to identify the causes and mitigation efforts. Data collection was carried out using survey methods and field observations, then the data were analysed descriptively. The research results show that the estimated lost crab gillnets potential in 1 month was 16 units (320 pieces) with a total weight of 1,137 kg. Meanwhile, in 1 year it is estimated that there will be 166 units (3.320 pieces) with a total weight of 11.375 kg or with a total loss value of IDR 573,750,000. The estimated abandoned crab gillnets potential in 1 month was 0.3 units (6 pieces) with a total weight of 23 kg, while in 1 year it is estimated that there will be 3 units (60 pieces) with a total weight of 230 kg and a loss of IDR 14,500,000. This study proposes a mitigation efforts including dissemination of the negative impacts of ALDFG and ghost gear, reporting program of lost fishing gear, providing incentives and implementing gear marking.

Abstract

Blue swimming crab (Portunus pelagicus) is the dominant catch in Betahwalang, Demak, and the most important export fish commodity, particularly to USA. The high demand for this crab has been promoting an excessive fishing effort, causing a decrease in the crab's natural stock. This study aims to investigate the biological condition of P. pelagicus on the northern coast of Central Java and assess the crab stock exploitation status in this study area. Carapace width, body weight, Gonad Maturity Stages (GMS), and sex of crab samples were collected from the fishers and collectors landing sites or meeting points. This study employs a simple random sampling technique with no replacement. This study revealed that the maximum carapace width of female crabs was 56-164 mm, and the estimated carapace width at first maturity (Lm) was 98.2 mm. The relationships between carapace width and body weight between male and female crabs indicated positive and negative allometric growth patterns. During this assessment, the P. pelagicus stock indicated an 'over-exploited status, with an LB-SPR parameter of 19 percent and an exploitation rate (E) of 0.66. Management measures such as minimum legal size, reduced effort, and open-close areas and seasons should be implemented to achieve sustainable use of the crab fishery.Keywords:Blue swimming crabFishing gearDemak watersCarapace lengthSpawning potential ratio

Abstract

Sharks is the dominant bycatch of purse seine and bottom longline vessels that landed in Kutaraja ocean fishing port, particularly pelagic thresher shark species (Alopias pelagicus). The management of shark fisheries in Aceh water is not well implemented. According to the IUCN red list, the pelagic thresher shark has been classified as an endangered species. The capture and trade of pelagic thresher sharks are regulated by CITES (Appendix II). So that Indonesia has to comply with the procedures of CITES due to it has been adopted through the Decree of Minister of Marine Affairs and Fisheries of the Republic of Indonesia Number 61/PERMEN-KP/2018. However, the exploitation and trading of the A. pelagicus continues and is not properly managed. It will threaten the extinction of the pelagic thresher shark population and in terms of a negative image of fisheries management in Indonesia, in particular. Thus, integrated management such as the ecosystem approach to fisheries management (EAFM) is needed to solve this problem. This study aims to evaluate the fisheries management status of the pelagic thresher shark based on EAFM indicator of fish resources domain, focusing in the Kutaraja ocean fishing port. This research was conducted by field measurement and interviews with key stakeholders. Data were analyzed using a multi-criteria analysis (MCA) approach through development of a composite index. The results showed that the trend of CPUE tends to fluctuate in the last 5 years. The total length of the sharks was relatively constant. The proportion of juvenile pelagic thresher sharks was 16% male, and 28% (female), and the shark was bycatch (1%) of the purse seine fishery, the fishing ground was getting further away and seemed to go close to the shark habitat. Based on this assessment, one could conclude that shark's fishery resources were in 'good' category, however, some indicators need to improve through better fisheries management actions.Keywords: EAFM; Alopias pelagicus; pelagic thresher shark; Kutaraja ocean fishing port

Abstract

Taurusman AA (2010) Community structure of macrozoobenthic feeding guilds in responses to eutrophication in Jakarta Bay.Biodiversitas 11: 133-138. The group of benthic fauna which feed on the same food sources are classified as a feeding guild. The objective of the present study was to evaluate the distribution and composition of macrozoobenthic feeding guilds along gradient of organic enrichment (trophic states) in Jakarta Bay. The result of the present study was shown that at the hypertrophic stations of the bay dominated by species of surface deposit feeding polychaetes such as, Dodecaceria sp., Cirratulus sp., Capitella sp., and Spionidae. The eutrophic zone of the bay was dominated by suspension feeding bivalves Mactra sp., Chione sp. The offshore area (mesotrophic zone)showed a high diversity of species and feeding guilds compared to other areas. The patterns of feeding guilds in the mesotrophic zone indicated a higher stability of macrozoobenthos community, indicated by the presence of deep-deposit feeder (e.g. Acetes sp.), surface deposit feeders (e.g. Prionospio sp.), suspension feeders (e.g. Chione sp.), and carnivores (e.g. Nephthys sp.) in comparable proportions.The structure of macrozoobenthic feeding guilds in an eutrophic coastal water is positively related to the quantity and quality of organic matters (eutrophic states), and the capability of benthic species in adaptation to such environmental condition.Key words: macrozoobenthos, feeding guild, eutrophication, coastal water, Jakarta Bay.

Abstract

Madduppa H, Taurusman AA, Subhan B, Anggraini NP, Fadillah R, Tarman K. 2017. DNA barcoding reveals vulnerable and not evaluated species of sea cucumbers (Holothuroidea and Stichopodidae) from Kepulauan Seribu reefs, Indonesia. Biodiversitas 18: 893-898. DNA Barcoding is a tool in the molecular taxonomy which allows a rapid and precise identification. This tool is needed to mitigate difficulties in identifying species of sea cucumbers in Indonesia. This study was conducted to reveal species diversity in sea cucumbers (Holothuridae and Stichopodidae), commonly harvested in the Kepulauan Seribu reefs, northern Jakarta, Indonesia, by using mitochondrial DNA. Neighbor-joining phylogenetic trees were reconstructed using the Kimura-2 parameter with 1000 of bootstrap values. The genetic distance within and between species was investigated. Conservation and trade status of the species were determined using IUCN and CITES, respectively. DNA barcoding using mitochondrial Cytochrome oxidase 1 (COI) revealed 7 species from 96 samples, of which 4 species belonged to the Stichopodidae (Stichopus herrmanni, Stichopus ocellatus, Stichopus horrens, Stichopus monotuberculatus), and 3 species to the Holothuridae (Bohadschia bivittata, Actinopyga lecanora and Holothuria leucospilota). Phylogenetic analysis showed that the two families were separated with a high bootstrap value. The neighbor-joining tree supported the result of identification of the sea cucumber species. The ingroup haplotypes were clustered into four main clades. Stichopus herrmanni and S. ocellatus were identified as closely related, which matches their morphological characteristics. Bohadschia bivittata is the most distinct species from other species due to the formation of a separate clade in the phylogenetic tree. Stichopus. horrens and S. monotuberculatus were also identified as very closely related, which might explain the frequent morphological misidentification of both types. The conservation status determined one of the investigated species was categorized as vulnerable, one as least concern, one as not evaluated, and four species in data deficient. The population trend of S.s herrmanni was recorded to be decreasing, whereas it remained unknown for the other 6 species. Surprisingly, all identified species in this study were not evaluated yet by CITES. This study suggests that a proper field monitoring and the establishment of a valid list of commercial and scientific names for the sea cucumbers harvested in Kepulauan Seribu is necessary. This would be valuable for keeping trade records and managing and conserving the targeted sea cucumber species in the region.

Abstract. Erizal A, Wiyono ES, Taurusman AA, Zulkarnain. 2025. Evaluating the utilization status of banana prawn (Penaeus merguiensis) in the Mukomuko Waters, Bengkulu, Indonesia. Biodiversitas 26: 1164-1170. Since the 1980s, the prawn resources in the Mukomuko Waters (Sumatra, Indonesia) have been subject to exploitation through shrimp mini-trawling, causing high levels of pressure due to the intensive trawling in a relatively small fishing area. It is essential to implement appropriate management measures to ensure the sustainability of the prawn resources. The objective of this study is to assess the exploitation status of banana prawn (Penaeus merguiensis) in order to provide the basis for sustainable prawn management. A simple random sampling technique was employed to obtain a representative sample of the prawn stock. The sampled catch of P. merguiensis in Mukomuko Waters was predominantly female. The result of the relationship between length and weight species analysis demonstrates a negative allometric growth pattern. The Gonad Maturity Level (GML) of P. merguiensis was found to be dominated by GML II and GML III categories, indicating fish catch was developing virgin and maturing. Fishing mortality (F) was found to be higher than the natural mortality (M), with an exploitation rate (E) of 0.69. The Spawning Potential Ratio (SPR) was determined to be 0.20, further indicating that P. merguiensis in Mukomuko Waters is currently overexploited. Based on these findings, two management strategies are proposed: regulating the operation of shrimp mini-trawls based on the time and place of fishing activities and replacing shrimp trawls with more environmentally friendly fishing gear.
