Becasue the river carries nutrient-rich sediment downstream from its source. This produces a very fertile medium for plants to grow in. Fish and animals are attracted to the plants as a food source - and predators will prey on those creatures.

Some of the most fertile regions in the world include the Nile River Valley in Egypt, the Indo-Gangetic Plain in India, the Great Plains in the United States, and the Pampas in Argentina. These regions have nutrient-rich soil, adequate water supply, and favorable climate conditions for agriculture.
The most fertile soil is typically found in regions with a combination of factors, such as a temperate climate, abundant rainfall, and well-draining soil. Areas like the Midwest in the United States, the Nile Delta in Egypt, and the Ganges River plains in India are known for their highly fertile soil due to these favorable conditions.
Most delta regions consist primarily of fish and waterfowl.
Most of it seemed fertile, however, most will probably say the Mekong Delta. But that region is extremely wet (seemingly flooded).
