Large-bodied animals, such as the Mekong giant catfish ( Pangasianodon gigas ), may modify prey communities and affect their potential competitors for food resources by consuming large quantities of prey. The Mekong giant catfish is a key representative of freshwater megafauna and is stocked in rese...
