abstract = {Fish migration is a crucial ecological process that supports fish reproduction, population stability, and fisheries productivity. In India, the migration of fish species is closely regulated by environmental cues such as monsoon rainfall, river discharge, water temperature, and coastal productivity. Climate change is increasingly disturbing these natural cues through rising temperatures, altered monsoon patterns, changing river flow regimes, and warming coastal waters. As a result, changes are being observed in the timing, routes, and success of fish migration in both freshwater and marine ecosystems. Migratory species such as Indian major carps, catfishes, hilsa, sardines, and mackerel are particularly affected. These changes have direct implications for fish production, aquatic biodiversity, and the livelihoods of fishing communities. This overview paper examines the major climate-related drivers influencing fish migration in India, discusses observed changes in freshwater and marine systems, and highlights management and adaptation measures required to sustain fisheries under a changing climate.},
