“…The biggest management challenge is our inadequate understanding of the social dimensions of these interactions and the inevitable uncertainties concerning both animal and human behaviors (Panagopoulou et al, 2017;Whitty, 2018;Mendoza-Portillo et al, 2020). Human behavior and fishery socioeconomics, in particular, play a key role in effective management of interactions and very few studies address these limitations (Northridge et al, 2017;Lewison et al, 2018).…”

Marine mammal interactions with fisheries, such as bycatch and depredation, are a common occurrence across commercial and small-scale fisheries. We conducted a systematic review to assess the management responses to marine mammal interactions with fisheries. We analyzed literature between 1995 and 2021 to measure research trends in studies on direct and indirect interactions for: (i) high and low to middle-income countries, (ii) fishery operations (commercial and small-scale), and (iii) taxonomic groups. Management responses were categorized using the framework described previously in peer-reviewed studies. Marine mammal bycatch remains a major conservation concern, followed by marine mammal depredation of fishing gear. A high proportion of studies concentrated on commercial fisheries in high-income countries, with an increase in small-scale fisheries in low to middle-income countries between 1999 and 2020. The insufficient understanding of the social dimensions of interactions and the inevitable uncertainties concerning animal and human behaviors are major challenges to effective management. Despite the key role of human behavior and socioeconomics, we found only eight articles that incorporate human dimensions in the management context. Integrating social dimensions of marine mammal interactions with fisheries could help in setting pragmatic conservation priorities based on enhanced understanding of critical knowledge gaps. An area-specific adaptive management framework could be an effective tool in reducing the risk to marine mammals from fisheries by coupling technical solutions with socio-economic and political interventions. We conclude that despite the vast body of literature on this subject, a “silver bullet” management solution to marine mammal interactions with fisheries does not yet exist.

“…The wider implementation and effective enforcement of conservation measures can be severely limited by socialeconomic factors (Mendoza-Portillo et al, 2020). For example, small-scale fishers in the developing world are unlikely to have the financial resources to implement technological interventions.…”

“…There are five communities in which the majority of fishers are in patron-client arrangements, three urban and two rural (Cinti et al 2010b, Bennett and Basurto 2018, Manjarrez-Bringas et al 2018, Siegelman et al 2019. There are twelve communities in which the majority of fishers belong to cooperatives, ten rural and two urban (Jiménez-Badillo 2008, Hoffman 2014, Velez et al 2014, Méndez-Medina et al 2015, López Torres et al 2018, Torre et al 2019, Mendoza-Portillo et al 2020, Quintana et al 2020. In three communities, two urban and one rural, approximately one-half of all fishers belong to a cooperative, whereas the other half work for patrons (Jiménez-Badillo 2008, Barr andMourato 2009, Bennett andBasurto 2018).…”

Most small-scale fisheries (SSFs) in the developing world are exploited by rural communities, but global trends in coastal urbanization and development are rapidly transforming many SSF landscapes. The implications for livelihood resilience, or the capacity of a livelihood to overcome shocks and stresses, remain unknown. The environmental and economic shocks and stresses experienced by SSF communities are becoming more frequent and severe, highlighting the urgent need to understand how urban and rural SSF contexts influence how fishers build livelihood resilience. To shed light on this issue, we performed a systematic review of the Mexican SSF literature to compare constructions of livelihood resilience across urban and rural communities. Our findings suggest that attributes innate to urbanness and ruralness may influence how these communities and individuals build livelihood resilience. Specifically, our results suggest that population density, isolation, and the diversity of jobs available are associated with several indicator variables for livelihood resilience. Moreover, we find that the greatest threats to livelihood resilience in urban communities are weak incentives to cooperate and threats to ecosystems, while the greatest opportunities to achieve livelihood resilience are easier access to education and ample prospects for additional employment outside the fishing sector. In contrast, livelihood resilience in rural communities is most threatened by the relatively fewer opportunities for education and additional employment, but benefits from strong incentives to cooperate. Efforts to bolster livelihood resilience within SSF communities would benefit from considering these different opportunities and challenges presented by urban and rural contexts.

“…Small-scale fishing (SSF) contribute significantly to global and local food security, employment, and viable livelihoods (Stanford et al 2017). The importance of SSF also extends to culture and heritage, and in many instances, they offer a livelihood for many people besides employment (Chuenpagdee et al 2019, FAO 2020, Mendoza-Portillo et al 2020.…”

Small-scale fishing (SSF) is a relevant economic activity worldwide, so sustainable development will be essential to assure its contributions to food security, poverty alleviation, and healthy ecosystems. However, the wide diversity of fisheries, their complexity, and the lack of information limit the ability to propose/evaluate management measures and plans and their effects on communities and other productive activities. The state of Baja California Sur, Mexico, our study case, ranks as the third place in national fisheries production, possesses SSF fleets, has a wide variety of fisheries that share fishing areas, fishing seasons, and operating units. In this work, assuming SSF as a complex system were proposed deep learning models (DLM) to forecast the catch volumes, evaluate each input variable's importance, and find interactions. Environmental variables and catch fisheries were tested in the DLM to estimate their predictive power. Different DLM structures and parameters to find the optimal model was used. The variables that presented higher predictive power are the environmental variables with R = 0.90. Moreover, when used in combination with the catches from other areas, the performance of R = 0.95 is obtained. Using only the catches, the model has an R = 0.81. This model allows the use of variables that indirectly affect the system and demonstrates a useful tool to assess a complex system's state in the face of disturbances in its variables.
