Coral Reef Fisheries Management and Conservation

Coral reef fisheries constitute a critical component of tropical marine ecosystems, supporting food security, livelihoods and coastal resilience for hundreds of millions of people worldwide. The management and conservation of these fisheries hinge on balancing extraction with the maintenance of ecological integrity and ecosystem services. Core objectives include sustaining fish biomass and community structure, preserving functional diversity and safeguarding trophic interactions that underpin reef resilience. Strategies encompass the establishment of marine protected areas—including no-take zones—gear restrictions, adaptive catch limits and community-based governance frameworks. Recent advances have focused on multispecies reference points, spatial prioritisation of conservation actions and the integration of social and ecological data to enhance compliance and adaptive management. Climate change, habitat degradation and socio-economic drivers pose ongoing challenges, necessitating flexible, context-specific approaches that align local stewardship with national policy and global conservation targets. Emerging tools such as network-based social-ecological models, high-resolution biomass mapping and recovery-time projections are informing more precise, equitable and scalable management solutions across diverse reef seascapes.

Research from Nature Portfolio

Recent studies have developed multispecies sustainable reference points for coral reef fisheries by integrating global fish biomass and catch data, revealing widespread stock depletion and quantifying biodiversity–ecosystem function trade-offs under different management benchmarks. Interdisciplinary network modelling has demonstrated that positive ecological conditions—higher fish biomass and functional richness—are linked to cooperative social-ecological network closure among fishers, emphasising the role of community communication and collective governance in sustaining reef fish stocks. Comparative analyses of marine reserves against remote wilderness sites have established that remoteness and low human footprint serve as benchmarks for reserve effectiveness, suggesting that wilderness areas can guide reserve design and evaluate management outcomes.

The graph below shows the total number of articles in coral reef fisheries management and conservation across all publications each year (not limited to Nature Index journals).

Technical terms

Multispecies sustainable reference point: A biomass threshold derived from environmental conditions and catch rates for multiple fish species, used to assess and guide sustainable harvest levels.

Social-ecological network closure: A fully linked network structure among resource users and ecological resource nodes that fosters cooperative governance and positive ecological outcomes.

Marine reserve: A protected area of the sea established to limit or prohibit extractive activities, aiming to restore or maintain ecosystem functions and biodiversity.

No-take zone: A category of marine reserve where all forms of fishing and resource extraction are prohibited, designed to maximise conservation benefits.

Human-impact gravity: A metric quantifying the intensity of human influence on reefs based on population size and accessibility, used to predict the effectiveness of conservation measures.
