Abstract There is growing recognition that fisheries should be managed for all three pillars of sustainability: economic, social and environmental sustainability. Limited quantitative evidence exists on factors supporting sustainability, much less contribute to multiple dimensions To develop a broader understanding the influence performance fishery management systems in environmental, economic pillars, we examine 11 input conjectured successful using global dataset 145 case studies. The analysis indicates approaches are cross‐cutting sustainability varying extents. Importantly, exogenous can as important management, suggesting collaboration institutions with other public private sustainable development.

Abstract Despite improved knowledge and stricter regulations, numerous fish stocks remain overharvested. Previous research has shown that fisheries management may fail when the models assessments used to inform are based on unrealistic assumptions regarding fishers' decision‐making responses policies. Improving understanding of fisher behaviour requires addressing its diversity complexity through integration social science into modelling. In our paper, we review synthesize state‐of‐the‐art both science's representation in scientific models. We then develop experiment with an agent‐based social–ecological model formalizes three different fishing styles. Thereby reflect implications incorporation behavioural contrast it predominant assumption fishery models: practices being driven by rational profit maximizing. envision a next generation account for individual collective human behaviours. Through model, demonstrate how such is possible propose approach reducing uncertainty fisheries. This study serves lay foundations ecological relevant realistic assessment sustainability problems.

The sustainable governance and management of small-scale fisheries (SSF) is challenging, largely due to their dynamic complex nature. Agent-based modeling (ABM) a computational approach that can account for the dynamism complexity in SSF by entities as individual agents with different characteristics behavior, simulate how interactions give rise emergent phenomena, such over-fishing social inequalities. structurally realistic design agent-based models allow stakeholder, experts scientists across disciplines sectors reconcile knowledge bases, assumptions, goals. ABMs also be designed using any combination theory, quantitative data, or qualitative data. In this publication we elaborate on untapped potential ABM tackle challenges SSF, discuss limitations ABM, review its application published models. Our shows that, although few exist date, has been used diverse purposes, including research tool understanding cooperation over-harvesting, decision-support tool, participatory case-specific fisheries. Even though development often time- resource intensive, it only represent types, heterogeneity, actions interactions, thus doing justice nature which, if ignored lead unintended policy outcomes less SSF.

Bycatch poses a significant threat to marine megafauna, such as elasmobranchs. India has one of the highest elasmobranch landings globally, through both targeted catch and bycatch. As elasmobranchs contribute food livelihood security, there is need for holistic approaches bycatch mitigation. We adopt an interdisciplinary approach critically assess range hypothetical measures reducing capture in trawler fishery on India's west coast, using risk-based mitigation hierarchy framework. Data were collected landing surveys, interviews literature review, following potential management options their technical effectiveness socio-economic feasibility: (1) Spatio-temporal closures; (2) Net restrictions; (3) reduction devices (BRDs) (4) Live onboard release. Our study provides first evidence-based nuanced understanding this fishery, suggestions future conservation research efforts. Onboard release may be viable species like guitarfish, with moderate chances survival, was favored option among interview respondents due minimal impact earnings. While closures, net restrictions BRDs reduce capture, implementation will challenging under present circumstances potentially high fisher income. Interventions live can therefore used step towards ameliorating bycatch, while initiating longer-term engagement fishing community. Participatory monitoring help address critical knowledge gaps ecology. closures gear restriction then developed bottom-up long term. Overall, framework facilitated assessment guide decision-making. Scaling-up integrating case studies across different species, fisheries sites would support formulation meaningful plan India.

Abstract Meeting the objectives of sustainable fisheries management requires attention to complex interactions between humans, institutions and ecosystems that give rise fishery outcomes. Traditional approaches studying often do not fully capture, nor focus on these people ecosystems. Despite advances in scope scale encompassed by more holistic methods, for example ecosystem‐based approaches, no single method can adequately capture complexity human–nature interactions. Approaches combine quantitative qualitative analytical are necessary generate a deeper understanding illuminate pathways address sustainability challenges. However, combining methods is inherently challenging multiple from different, disciplinarily distinct origins, demanding reflexivity researchers involved. Social–ecological systems’ research has history utilising combinations across social ecological realms account spatial temporal dynamics, uncertainty feedbacks key components fisheries. We describe several categories (statistical modelling, network analysis, dynamic analysis controlled behavioural experiments) highlight their applications research, strengths limitations, data needs overall objectives. then discuss important considerations portfolio development process, including reflexivity, epistemological ontological concerns illustrate via three case studies. show that, expanding portfolios, will be better equipped study shaping contribute solutions management.

For future sustainable management of fisheries, we anticipate deeper and more diverse information will be needed. Future needs include not only biological data, but also that can come from fishers, such as real-time ‘early warning’ indicators changes at sea, socio-economic data fishing strategies. The industry, in our experience, shows clear willingness to voluntarily contribute experiential knowledge, there is little evidence current institutional frameworks for science are receptive equipped accommodate contributions. Current approaches producing knowledge support fisheries need critical re-evaluation, including the contributions industry make. Using examples well-developed advisory systems Europe, United States, Canada, Australia New Zealand, investigate three interrelated issues inhibiting systematic integration voluntary science: (1) concerns about quality; (2) beliefs limitations useability unique fishers’ knowledge; (3) perceptions impact on integrity science. We show whilst these real, they addressed. Entrenching effective science-industry research collaboration (SIRC) calls action specific areas; (i) a move towards alternative modes production; (ii) establishing appropriate quality assurance frameworks; (iii) transitioning facilitating governance structures. Attention must paid science-policy-stakeholder interface. Better definition industry’s role contributing improve credibility legitimacy scientific process, resulting management.

Among the various challenges facing tropical tuna purse seine fleet are need to reduce fuel consumption and carbon footprint, as well minimising bycatch of vulnerable species. Tools designed for forecasting optimum fishing grounds can contribute adapting changes in fish distribution due climate change, by identifying location new suitable grounds, thus reducing search time. While information about high probability find species could result a reduction. The present study aims at contributing more sustainable cleaner fishing, i.e. catching same amount target with less consumption/emissions lower bycatch.

Indeed, studies aid resilient setting taking into account climate‐driven effects on community size‐structure.
