Inland water fisheries in India play a crucial role in providing nutrition, employment, and livelihoods for millions of people, particularly in rural areas. They include rivers, lakes, reservoirs, ponds, and wetlands, each offering distinct ecological niches and productivity potential. Despite their importance, the development of inland fisheries in India faces multiple challenges that are both ecological and socio-economic in nature. One of the primary challenges is overexploitation of fish resources. With a growing population and increasing demand for fish as a protein source, traditional fishing practices have intensified. Many fishing communities rely on methods such as gill netting, drag netting, and poisoning, which are often unsustainable and reduce fish stocks over time. Overfishing not only diminishes the availability of commercially important species but also disrupts the ecological balance of aquatic systems. Pollution is another major issue affecting inland fisheries. Industrial effluents, agricultural runoff, and domestic sewage contribute to the deterioration of water quality in rivers and lakes. High levels of nutrients from fertilizers lead to eutrophication, causing algal blooms that deplete dissolved oxygen in water and result in fish mortality. Heavy metals and toxic chemicals from industrial discharge accumulate in fish tissues, rendering them unsafe for human consumption and affecting the health of both humans and aquatic fauna. Furthermore, sedimentation caused by deforestation, soil erosion, and unplanned urban development reduces the depth and productivity of water bodies, negatively affecting fish breeding and growth. Hydrological alterations, such as the construction of dams, barrages, and irrigation canals, also pose significant challenges to inland fisheries. Dams regulate water flow for irrigation and hydroelectric purposes but disrupt natural river ecosystems and fish migration routes. Many indigenous fish species rely on seasonal floods and riverine connectivity for spawning. The obstruction of migratory pathways leads to population decline of these species and favors more resilient but less commercially valuable species.
