The invention belongs to the technical field of 
fish processing, and particularly relates to a process for 
processing fishes cleanly, which comprises the following steps of: stunning the fishes instantly, namely stunning live fishes by using rated 
voltage so as to allow the fishes to have 
heartbeat but lose memory or stunning the live fishes in a closed bag by using 
carbon dioxide; 
cutting fish gills off, namely allowing a knife to extend into the fish gills from water outlet edges of the fish gills on sides of fish cheeks to 
cut the fish gills on both sides off; performing 
bloodletting, namely hanging the fishes of which the fish gills are 
cut off in a mode of allowing fishtails to be upward and fish heads to be downward for 
bloodletting, so that fish blood flows out of fish mouths until the fish blood is discharged completely from 
fish gill cavities; washing, namely washing blood in 
fish mouth cavities cleanly by using pressurized water conveyed from the fish mouths, and washing 
dirt and 
mucus on surfaces of fish bodies cleanly; and 
drying, namely 
drying the water on the surfaces of the fish bodies by using a water absorption material. The process has the advantages that the fishes are stunned instantly, so the slaughter effect is good; the 
bloodletting is complete in a mode of 
cutting the fish gills off, so fish 
flesh is not polluted; and the fish bodies are hung upside down, the bloodletting is complete, and time and labor are saved, so the process is suitable for 
processing various fishes, particularly globefishes cleanly.
