What is raw fish?
Fish originated in China with a long history and rich contents, and then spread to Japan, Korean Peninsula and other places. It is a very popular food in Japan and is called sashimi in Japan.
All fish with scales can be used as raw fish, such as herring, silver carp, grass carp and bighead carp. But don't use fish without scales because they contain mucus and are difficult to handle.
Raw fish should not be kept in sewage ponds. It is best to use spring fish, Qingshuihe fish and reservoir fish, and they must be live fish. Dead fish can't be raw fish.
