Subsistence fishery resources are aquatic biological stocks—typically fish and invertebrates—harvested primarily to meet the nutritional, cultural, and basic material needs of local or Indigenous communities rather than for commercial sale. As a research topic, they encompass assessment of stock availability, seasonal and spatial patterns of use, food security contributions, and vulnerability to environmental change and management regimes. Studies often integrate ecological monitoring with socio-economic and ethnographic methods to quantify harvest levels, document traditional ecological knowledge, evaluate co-management arrangements, and analyze how regulatory frameworks, climate variability, and habitat degradation affect the sustainability and accessibility of these resources.
