N1 - Funding Information:
We acknowledge all of the involved fishers and community members and those that led the revitalization of Hawaiian Moon Calendars, in particular Uncle Mac Poepoe, Kalei Nu'uhiwa, and the Hanalei Watershed Hui. Community support and guidance was provided by Hui Aloha Kīholo, Polanui Hui, Wailuku Community Managed Makai Area, Kailapa Community Association, and Hā'ena and Hana community members. Many collaborations were formed and relationships built with the help of Matt Ramsey, NOAA Fisheries Extension Agent. Special thanks to Lauren Mathews and Kanani Frazer for their assistance in the design of the moon calendars. Funding and support was provided by Conservation International Hawai'i and NOAA coral Reef Conservation Program award to the State of Hawaiʻi Department of Land & Natural Resources, Division of Aquatic Resources Award Number NA13NOS 44820014. Conservation International staff that worked diligently along with us on this research includes Luka Mossman and Kehau Springer. Support was also provided by The Nature Conservancy of Hawai'i. Finally, support and guidance from the Fisheries Ecology Research Lab at the University of Hawai'i at Mānoa members: Mary Donovan, Alex Filous, Jonatha Giddens, Whitney Goodell, Ily Iglesias, Haruko Muro-Koike, Keith Kamikawa, Kaylyn McCoy, Kosta Stamoulis, and Paolo Usseglio. We would also like to thank Keoki Stender for his contribution of marine life photos to the moon calendars. Approval of University of Hawai'i Animal Care and Use Committee was through protocol #13-1710 and formal exemption approval for gonad samples donated by fishermen. Use of human studies in this research was approved through IRB exemption #22394.

N2 - Small-scale fisheries across the globe provide critical food security, livelihoods, and human well-being, but are threatened by a combination of local and global stressors, including overexploitation, pollution, and climate change. Participatory approaches to management, especially those that incorporate local communities and customary knowledge can provide meaningful biological information that supports sustainable fisheries management and builds local adaptive capacity to changing ocean conditions. Through a collaboration between fishers, scientists, NGOs, and regulating agencies, we developed a low-cost, low-tech method to assess the seasonal spawning peaks, lunar spawning cycles, and size at maturity (L50) for key targeted reef fish, combining traditional knowledge and practice with modern scientific approaches, including gonadosomatic index (GSI) and histology. Two years of community-based monitoring resulted in data from 57 species and 15 families of reef and nearshore fishes (n = 2595), with detailed information for 10 species at 4 locations across the Hawaiian Islands. Comparisons between community-collected GSI data and scientifically (histologically) assessed spawning cycles and size at reproductive maturity produced similar results suggesting that these approaches can be applied in data-poor fisheries to assess spawning seasons and size at maturity (L50), both of which are critical needs for effective fisheries management. Semistructured surveys revealed a large body of local knowledge on spawning times and harvest practices based on allowing spawning to occur before harvesting and protecting small and large size classes, but little evidence that fishers understand temporal patterns of spawning. This suggests that monitoring methods that fill key gaps such as this and are congruent with these local knowledge systems and customary harvest practices may be key for local stewardship and adaptive management.
