📄 Abstract（原文）
1. Context: The global imperative to decarbonize energy systems has accelerated hydropower expansion, yet reconciling energy generation with the mitigation of downstream fish mortality remains a critical environmental engineering challenge. 2. Field Gap: However, the application of fish-friendly technology remains fragmented and primarily salmonid-centric, resulting in a mitigation gap where high-maturity engineering solutions often fail to meet the biomechanical requirements of diverse global ichthyofauna. 3. Purpose: This paper reports on a global synthesis of fish-friendly technologies, evaluating their mechanical principles, Technology Readiness Levels (TRL), and reported biological efficacies. 4. Methodology: We employed a multi-tiered systematic scoping review and qualitative content analysis of 154 studies, integrating the TRL framework to map the transition from laboratory proof-of-concept to field-validated operation. 5. Results: These results demonstrate that while structural passage systems have achieved TRL 9, emerging digital avatars and site-specific behavioral deterrents remain at lower maturity stages (TRL 3-4). Furthermore, we identify a fundamental failure in the widely used 95g acceleration threshold as a proxy for mortality, noting that rigid sensors likely overestimate impact severity compared to flexible biological organisms. 6. Conclusion: We conclude that achieving sustainable hydropower requires a paradigm shift toward engineering by design, prioritizing multi-species calibration and the digitalization of dam operations to synchronize energy loads with biological migratory pulses.
