Commercial fishery resources, as a research topic, encompass the biological stocks and populations of aquatic organisms (primarily finfish, shellfish, and other invertebrates) that are harvested for economic gain under regulated or unregulated fisheries. Study of these resources focuses on stock assessment, population dynamics, productivity, habitat dependencies, and responses to exploitation and environmental variability. It integrates fisheries biology, quantitative modeling, ecosystem-based management, and socio-economic analysis to determine sustainable yields, evaluate fishing impacts, and inform regulatory frameworks such as catch limits, gear restrictions, and spatial-temporal closures aimed at maintaining long-term viability of commercially targeted species and associated ecosystems.
More than 3,000 fish species have been caught in bottom trawls, with estimates suggesting the true number could be nearly double, according to the world's first global inventory.
