The present study addresses the crucial sustainability concerns in small-scale fisheries (SSF) against the backdrop of escalating anthropogenic activities and climate change impacts on marine fishery and ecosystems. Our study focused on a traditional fishery exploitation area spanning 12,646.12 km along the Southwestern Coast of Kerala, India, and explored four widely used fishing gears. We established an integrated decision-making VIKOR framework, and preferential modelling by incorporating techno-economic and environmental aspects to draw the optimal solutions. Leveraging 10 sustainability indicators, the boat seine emerged as the most sustainable gear, showcasing significant profitability (US$ 16,126/year net profit) and remarkable energy efficiency, surpassing gillnetters, longliners, and shore seiners by 8.4, 4.9, and 3.0 times, respectively. The Fuel Use Intensity (FUI) and CO emissions analysis (F value = 58.37, P < 0.0001) emphasizes the ecological implications. The developed VIKOR sustainability index, introduced in this study, effectively assesses gear efficiency and sustainability. Further, the study revealed that gear selectivity, technical specifications, and operational trajectories considerably influence the index dynamics. This research aligns with the global commitment to the Voluntary Guidelines for Securing Sustainable Small-Scale Fisheries (SSF Guidelines) and contributes scientifically to Sustainable Development Goals (SDGs). By bridging empirical rigor with international frameworks, the study could aid in sustainable fisheries management and environmental stewardship, deemed essential for the global pursuit of ecological, economic, and social sustainability in small-scale fisheries.

印度小型渔业 (SSF) 的能源效率和经济：基于 VIKOR 的可持续渔业管理多标准决策模型

本研究解决了在人类活动不断升级以及气候变化对海洋渔业和生态系统影响的背景下小型渔业（SSF）的关键可持续性问题。我们的研究重点是印度喀拉拉邦西南海岸绵延 12,646.12 公里的传统渔业开发区，探索了四种广泛使用的渔具。我们建立了综合决策VIKOR框架，并结合技术经济和环境因素进行优先建模，得出最优解决方案。凭借 10 项可持续性指标，船围网成为最具可持续性的渔具，展现出显着的盈利能力（净利润 16,126 美元/年）和卓越的能源效率，分别超过刺网渔船、延绳钓渔船和岸围网渔船的 8.4 倍、4.9 倍和 3.0 倍。燃料使用强度 (FUI) 和 CO 排放分析（F 值 = 58.37，P < 0.0001）强调了生态影响。本研究中引入的 VIKOR 可持续性指数可有效评估齿轮效率和可持续性。此外，研究表明，齿轮选择性、技术规格和运行轨迹对指数动态有很大影响。这项研究符合全球对《保障可持续小规模渔业自愿准则》（SSF准则）的承诺，并为可持续发展目标（SDG）做出了科学贡献。通过将严谨的实证研究与国际框架相结合，该研究可以帮助可持续渔业管理和环境管理，这对于全球追求小规模渔业的生态、经济和社会可持续性至关重要。
