Pangasius, also known as Pangas or Swai, is a freshwater fish, primarily found in Southeast Asia, particularly in the Mekong River basin. It's a popular choice in aquaculture due to its rapid growth, tolerance of various water conditions, and relatively low production cost. Pangasius is an omnivore, feeding on algae, zooplankton, and insects in its early stages, and later consuming fruits, crustaceans, and other fish. It's known for its adaptability, even tolerating low oxygen levels.
