Inland fishery resources are freshwater and estuarine fish, invertebrate, and associated aquatic biotic stocks that inhabit rivers, lakes, reservoirs, floodplains, wetlands, and inland brackish systems and are exploited for capture fisheries. As a research topic, they encompass the assessment of species composition, population dynamics, recruitment, and productivity under varying hydrological and environmental regimes, as well as the impacts of habitat alteration, pollution, hydropower, climate variability, and fishing pressure on stock status.
