As the question?

How do you clean monkfish? Fresh monkfish is simply gutted and gilled (leaving the swim bladder and liver) and cleaned.

Chop into large pieces, blanch in boiling water to remove surface mucus and fishy smell, brown and fish out, drain and set aside. (Be sure to blanch before stewing so as to completely remove the slime and fishy.)
