Peel the skin off the smoked eel and mackerel. Cut the fish into bite-sized pieces. Wash the dill, dab dry and cut into small pieces, except for a few twigs for garnishing. Whisk eggs and five tablespoons of water with a fork.
Season with salt and pepper. Heat oil in a pan. Add the eggs. Add the smoked eel, mackerel, crab and dill and let everything simmer for five minutes at medium heat. Carefully pull the egg mixture from the edge of the pan to the middle with a spoon.
Serve garnished with remaining dill.
