fish migration

Fish migration is the seasonal movement of fish from one area to another, often for spawning, feeding, or habitat needs. Many fish travel upstream to freshwater rivers to reproduce or move to different environments that offer better conditions at certain times of the year. These migrations can cover long distances and are driven by environmental cues like water temperature, flow, and day length. Migration helps ensure fish access to ideal habitats for survival and reproduction, maintaining healthy populations and supporting ecosystems.
