African fish eagles depend on productive freshwater lakes and rivers facing increasing pollution, overfishing, and wetland degradation across sub-Saharan Africa.
African fish eagles in degraded lake and river systems face food insecurity as prey fish become scarce and turbid water prevents the visual hunting they depend on. Eagles consuming fish poisoned by illegal fishing chemicals suffer poisoning with variable welfare impacts from sub-lethal effects to death. Territorial eagles defending depleted fishing areas have lower body condition and breeding success. Wetland protection and water quality improvement that restores prey fish populations directly improves eagle welfare.
