African penguins are Endangered and declining rapidly as industrial fishing has depleted anchovy and sardine stocks in their foraging range, forcing longer, more energetically costly foraging trips.
African penguins are experiencing chronic nutritional stress as prey fish are depleted from their historical foraging grounds. Longer foraging trips mean adults spend more time at sea and less time warming and protecting chicks, increasing chick starvation and predation. Adults returning from extended foraging trips show measurable body condition declines. Chicks that are food-deprived grow slowly, are less able to thermoregulate, and face higher mortality. Oil spills periodically cause acute mass mortality and welfare crises requiring intensive rehabilitation. Rescued and rehabilitated penguins experience handling stress during cleaning and veterinary treatment, though their welfare outcomes are generally good. The overarching welfare crisis is starvation-driven collapse, which requires addressing industrial fishing pressure at the policy level.
