Summary: Understanding fishing effort allocation is crucial for spatial management planning in fisheries, particularly in small-scale fisheries with multi-specific contexts. Random Walk models prove to be useful for modeling small-scale fleets operating in southeast Mexico, with the Composite Correlated Model identified as the most suitable model for this fleet. Further studies should consider increasing the number of fishing trips and conducting specific studies by gear and fishing method, along with applying relative and absolute fit tests to compare the performance of RW models.

Summary: Tourism development has complex impacts on fisheries, leading to a decline in fishery participation but also an increase in fishing effort and improvements in fishing methods, resulting in increased fishing pressure. The impacts vary depending on contextual factors in the biophysical environment and socio-political systems, highlighting the importance of anticipating and planning for sustainable tourism development and fisheries management.

Summary: The Socotra Archipelago in Yemen heavily relies on small-scale fishing, but the reporting of fisheries catches has been incomplete. This study reconstructs the total catches and fishing effort in the region from 1950 to 2019, finding that the officially reported catch accounts for only 20% of the total reconstructed catch. The findings suggest overexploitation of resources and highlight the importance of sustainable management for the fish stocks in the Socotra Archipelago.

Summary: The volume and value of fish catches by Indonesia's small-scale fisheries declined significantly after the COVID-19 pandemic, with more than 90% of active fishers and traders reducing their activities. Despite a decrease in the average price per kilogram of fish, fishers who continued fishing had higher catches and maintained their daily catch value. High value fisheries for export were more negatively impacted compared to lower value species sold in local markets.

Summary: This study examined small-scale fisheries data from 27 points in Brazil's northeastern region over 3 years using Benford analysis. The results showed that 20% of the fish landing data were highly inaccurate, especially from non-motorized canoes. Data from harbors in remote locations, particularly monthly catch values reported by several boats, were of poorer quality. Monthly data was found to be less accessible through this method compared to daily data.

Summary: Is there a limit to the amount of fish that can be taken from the sea? This paper examines the shift in fisheries governance from regulating and establishing Maximum Sustainable Yields to collectively co-managing territories and ecosystems. The study highlights the challenges faced by fishers in defining the limits of their agency and argues for the adoption of an ethos of collective self-limitation in fisheries governance.

Summary: This study evaluated the socio-economic performance and evolution of two small-scale fishing communities in northern Peru using the Sustainable Livelihoods Approach. The results revealed that the fishers had low human and financial capital assets, strong social capital assets, and experienced improvements in physical capital assets while reporting declines in natural capital assets. The findings also indicated that the fishers' wellbeing was highly vulnerable to external environmental and economic drivers as well as poor governance. The study suggests potential avenues for escaping the social-ecological trap and improving their wellbeing based on commonly suggested livelihoods strategies found in the literature.

Summary: Small-scale fisheries in Indonesia, which involve 90% of the total number of fishers and provide significant employment for coastal communities, face challenges with catch reporting and monitoring due to the scattered nature of fishers across thousands of islands. Collaborative efforts between the Indonesian Ministry of Marine Affairs and Fisheries and the USAID Sustainable Ecosystems Advanced (SEA) Project have initiated the development of a fishing logbook system to address these challenges. The holistic intervention using sustainable livelihood approach aims to establish a systematic approach for catch monitoring in Indonesian small-scale fisheries, recognizing the tradeoff between an ideal logbook system and an applicable model for this context.

Summary: In small-scale fishing communities in the Myeik Archipelago in Myanmar, 49% of surveyed fishers were aware of the nationwide ban on shark fishing, while 24% of shark fishers tended to be younger individuals who did not own boats. Compliant fishers were motivated by fear of sharks and lack of capacity, while food and income were key motivations for non-compliance.

Summary: Addressing the various factors affecting small-scale fisheries requires collaboration across different regions, geographical scales, and administrative levels to ensure alignment between governance systems and the problems they aim to solve. This study explores the network configurations of the Galapagos small-scale fishery governance system through descriptive statistics, exponential random graph models (ERGMs), and qualitative data analysis, revealing key players and network structures that are crucial for collaboration and robustness.

Summary: This study investigated the trends in fishing effort and catch per unit effort of small-scale marine fisheries in the Mozambique Channel region in East Africa from 1950 to 2016. The study found that with an increase in fishing effort, there was a 91% decline in overall catch per unit effort, indicating a potential risk of overexploitation in small-scale fisheries.

Summary: This study aimed to understand the vulnerability of five diverse SSF communities in northern Peru amid COVID-19 and identify key sensitivity indicators that influence their response. The results showed that communities with high social capital responded better to COVID-19 impacts, while those with low social capital had a passive response. Adaptive strategies of SSF included diversification of fishing activities, selling marine products at local markets, establishing agreements with authorities, and utilizing technology to enhance local seafood value chains.

Summary: The study revealed fishing activities, primarily trawling, on high-seas seamounts of the Northwestern Hawaiian Ridge and Emperor Seamounts, with Japanese and Korean vessels predominately involved. Scientific surveys showed visible scars from bottom contact gear and provided data on areas with abundant megafauna, which could aid in VME management and further closures.

Summary: Estuaries and coastal areas are undergoing rapid changes due to climate change and sea level rise. This research presents a salinity transport model for Biscayne Bay and investigates the potential impacts of altered precipitation, increased salinity/temperature, and sea level rise on bay salinity. The findings suggest that current restoration plans may not be sufficient to maintain current salinity conditions, and management measures such as urban greening, artificial groundwater recharge, and water consumption reduction should be considered.

Summary: The study shows that spatiotemporal simulation modeling is an effective tool for investigating management options in ecosystem-based fisheries management. It demonstrates that fisheries restricted areas can help rebuild the biomass of exploited stocks, but their effectiveness depends on the size and location of the areas. The study also suggests that a parallel reduction in total fishing effort is necessary to achieve the highest benefits of protection.

Summary: This study addresses the storage space allocation problem of container yards based on the dual-cycle operation mode. A mixed integer programming model is established to optimize container transportation distance. The results show that dual-cycle operation can decrease transportation distance and the space allocation method based on it is more effective than traditional methods. The study also provides management insights for container ports and suggests effective solutions for bottleneck problems.

Summary: This study aims to identify and explore the information requirements at different stages of the decision-making process of coastal nature-based solutions (NbS). The study found substantial differences in information requirements across the decision-making stages, with values and indicators becoming more specific and concrete as the stages progressed. The study also suggests that future changes in the information required for decision-making on coastal NbS can be anticipated and prepared for.
