Fish are heavily influenced by the nature of the flood regimes of the rivers in which they live. These fluctuate naturally from year to year but recently increasing pressure on water for a wide range of uses other than fisheries has led to human activities that have substantially altered the flood regimes of many rivers throughout the world. This has resulted in the loss of fish production and biodiversity. There are now efforts to mitigate for these changes that include release of artificial floods from dams or polder sluices. The typical flood curve contains several characteristics that may influence the survival and growth of the individual fish species. Understanding of these characteristics will help design appropriate flood curves and maximize benefits from the water available.
