Sashimi, also known as sashimi, raw fish and sashimi, refers to a dish in which fresh fish and shellfish are sliced and dipped in seasonings for direct consumption. Originated in China, it is a common fish dish in ancient China, and now it is popular in Japan, Korean Peninsula and other places. The gradual decline of raw fish in ancient China may be due to freshwater fish as the main ingredient. Generally, freshwater fish have more parasites than marine fish.
