Dugongs are marine mammals that are primarily found in warm coastal waters, and they are not a traditional food source for most Asian cultures. In some regions, particularly in parts of the Pacific and Indian Oceans, there may be instances of hunting dugongs for their meat, but this practice is increasingly rare and often regulated due to conservation efforts. Overall, dugongs are more commonly protected species rather than a staple in Asian diets.
