摘要

Ensuring the sustainability of swimming crab (Portunus spp.) capture fisheries requires adaptive governance frameworks that are grounded in robust monitoring systems and inclusive co-management practices. This study comparatively examines crab fisheries in Japan and the Philippines using the Social-Ecological Systems framework, integrating field interviews, catch data, and policy reviews across six coastal communities: Taytay (Palawan), Batad (Iloilo), and Hadji Panglima Tahil (Jolo, Sulu) in the Philippines, and Ehime, Hiroshima, and Yamaguchi in Japan. Key governance contrasts emerge: Japan employs cooperative-based enforcement and longstanding stock enhancement programs but relies on species-aggregated monitoring amidst declining Gazami (P. trituberculatus) catches. The Philippines, meanwhile, demonstrates localized co-management success in Taytay yet struggles with weak enforcement and data gaps elsewhere. Monitoring capacity varies significantly—Taytay maintains detailed local records, while Japan lacks species-specific data despite formal systems. Stakeholder roles, gear types, and bait usage reflect ecological and institutional conditions, shaping fishing effort and compliance. Despite shared challenges—including the absence of Total Allowable Catch limits and fragmented data systems—both countries offer valuable lessons. Cross-country learning and adaptive, resilience-based governance models may enhance the sustainability of small-scale crab fisheries across tropical and temperate coastal contexts.
