The Scoop Light Fishing (SLF) gear is an innovative fishing technology capable of producing catches exceeding one ton per trip. Despite its high productivity and ability to operate during all lunar phases, including bright-moon periods, its construction and effective fishing time have not been scientifically assessed. The purpose of this study is to examine the construction of the SLF and identify its effective fishing period in the waters of Bero Village, Pulau Tiga, West Muna Regency. The research employed a survey method, with data collected through direct observation and interviews, and analyzed using qualitative and quantitative approaches. Quantitative analysis included a normality test and a one-way ANOVA at the 0.05 significance level, followed by an LSD post hoc test. The results show that the SLF consists of two main components: an elongated scoop-net bag directly connected to the fish hold and a square lighting system comprising four panels equipped with white and yellow lights, producing a total output of 4,765 watts. The SLF operates effectively during all lunar phases; however, fishing effectiveness is highest during the full moon phase (Q.III), as indicated by a significance value of less than 0.05. Keywords: Effectiveness; moon phases; scoop light fishing

The utilization of shark species in Indonesia still encounters legal violations, thus necessitating an effective surveillance system. This study aims to identify the issues within the surveillance systemregarding the utilization of shark species at the Cilacap Ocean Fishing Port (PPS Cilacap). The studyuses a system approach, limited to the system analysis stage. The results showed that there are stillproblems in the shark species utilization monitoring system at PPS Cilacap. These problems resultin violations that continue to occur, especially concerning the legal regime of Regional FisheriesManagement Organizations (RFMOs). The problems identified in the conclusions of this study coverseveral aspects. Regarding regulations and institutions, the mandate holders lack synergy, lawenforcement remains weak, and support from management institutions for surveillance agencies isinsufficient. Regarding surveillance procedures and budget, the existing standard operatingprocedures (SOPs) do not represent surveillance needs in accordance with legal regulations onshark management, and the available budget is inadequate. Regarding facilities and infrastructure,surveillance facilities for shark species have not been utilized at PPS Cilacap, and unreported fishingstill occurs. Regarding human resources, the number of fisheries inspectors does not meet actualneeds, while vessel captains and owners' knowledge and legal awareness remain limited. Toaddress these issues, the recommended strategies include the maintenance and development ofport facilities at PPS Cilacap, the integration of information systems among institutions, thedissemination of shark governance, the recruitment, education, and training of fisheries inspectors,the revision of SOPs, and comprehensive law enforcement. Keywords: PPS Cilacap; shark; surveillance system

The behavior of the giant freshwater prawn (Macrobrachium rosenbergii) towards folding traps is significant to identify, given its complex movement patterns and dependence on the fishing gear. This study aimed to investigate the behavioral responses of M. rosenbergii to folding traps by examining spatial movement patterns and assessing trap effectiveness across three time periods (morning, noon, and night). To achieve this, an experiment using a behavioral event analysis approach was employed to reconstruct movement trajectories, X–Y coordinates, and behavioral phases. Furthermore, the Mann–Whitney U test was utilized to compare the distributions of entry and exit frequencies as an indicator of trap retention efficiency. The results showed that prawns exhibited adaptive, stepwise spatial behavior, beginning with external exploration characterized by zigzag paths, circular movements, and approach–retract cycles, before entering the trap with an average latency of 8–10 minutes. Furthermore, 95 of 160 individuals (59.38%) successfully entered the trap, whereas 65 (40.62%) exited after initial contact. The Mann–Whitney test confirmed a significant difference between entry and escape numbers (U=63;p<0.05), with the number of successful entries being significantly higher than the number of escapes, thereby validating the structural effectiveness of the folding trap. The temporal distribution indicated that nighttime was the most effective period, with 60 individuals entering, substantially more than in the morning (28) or at noon (7). These findings highlight that the effectiveness of folding traps is closely linked to the nocturnal behavioral patterns of M. rosenbergii. Keywords: Behavioral event analysis; folding trap; Macrobrachium rosenbergii; movement pattern; trap retention effectiveness

Issues surrounding the implementation of the Post-Production Non-Tax State Revenue (PNBP) program in Indonesia, particularly at the Nizam Zachman Marine Fisheries Port, center on a lack of accountability in catch reporting, which serves as the primary basis for calculating levies. The accuracy of this data is severely compromised by inconsistencies in the competencies of enumerators; however, the Directorate General has not yet established quantitative and operational standards for these competencies. This study aims to address this gap by developing a robust competency framework for post-production PNBP enumerators using a Design Science Research (DSR) approach. This framework was developed through a systematic content analysis of scientific literature and PNBP regulations, followed by two stages of expert validation. The resulting framework categorizes three fundamental dimensions—knowledge, skills, and attitudes—into 22 specific indicators. This study reveals that the framework consists of knowledge (38%), skills (32%), and attitudes (30%). The dominance of the knowledge dimension underscores that a deep understanding of regulations and technical fish identification is crucial for ensuring data integrity. Ultimately, this framework provides a structured foundation for improving recruitment, training, and performance evaluation to enhance the accountability of the PNBP system.

The Flores Sea is a tuna fishing area with limited data on the fishery, including vessels, fishing gear, fishing grounds, seasonality, fuel consumption, catch volume, and the size of tuna caught. This study examined and analyzed the fishing grounds of small-scale hand-line tuna fishermen and the size of tuna caught in the Flores Sea following the research methodology described by Ebata. The results showed that the fishing vessels were suitable for catching tuna with hand-line fishing gear and operated throughout the year. The fishing grounds were in tuna habitat and migration routes in the Flores Sea and were influenced by the fishing season. The composition and production volume of the sampled catch (n = 1,210) was dominated by yellowfin tuna (Thunnus albacares) in the length/weight range 34-46.2 cm/1.5-3.9 kg (84.5%, 1,023 fish), followed by larger yellowfin tuna (local name opo') in the length/weight range 61-211 cm/10.5-80 kg (183 fish 15.1%), with big eye tuna (Thunnus obesus) contributing just four fish (0.33%) in the length/weight range 110-189 cm/38.5-58 kg. The catch composition indicates that the yellowfin tuna fishery is likely to be unsustainable, marked by range collapse with a southwards shift towards fishing grounds further from the base in the Flores Sea. Keywords: Fishing season; Flores sea; length-frequency distribution; small-scale handline; Thunnus albacares.

Yellowfin tuna (Thunnus albacares) is a high-value fishery commodity. Many yellowfin tuna are caught in the waters of the Makassar Strait using purse seines and longlines targeting juvenile-sized fish. This study aimed to compare the length-frequency distribution and the estimated length at first capture (Lc) of Yellowfin tuna (Thunnus albacares) caught by purse seine and handline fisheries. The study was conducted in Majene and Polewali Mandar Regencies from August to November 2022. Sampling was performed randomly at fish collectors, with fork length measured using a tape measure with a precision of 0.1 cm. The data analyzed consisted of 479 individuals from purse seine catches and 1,620 individuals from longline catches. The results showed that the size structure of the purse seine catch ranged from 14 to 49.5 cm and was dominated by the 22.5 cm size class, while the handline catch ranged from 15.5 to 165 cm and was dominated by the 55 cm size class. The first-catch size (Lc) for the purse seine was 23 cm and for the longline was 63.9 cm. Differences in size distribution and Lc between the two fishing gear types indicate distinct catch characteristics that can provide information regarding the utilization of yellowfin tuna resources. This information can be used to support the sustainable management of yellowfin tuna fisheries in the waters of the Makassar Strait. Keywords: Catch size; distribution; first capture size; handline; purse seine; yellowfin tuna
