In large bowl, mix shredded Bangus with celery, onion, carrot, parsley and singkamas.
Season with salt and pepper. Then mix well.
Scoop 1 to 2 tablespoons of the fish mixture and arrange on the lower part of the wrapper. Mold using your hands to form a long cylinder and partially press to compress the mixture. Secure the filling by folding both sides of the wrapper inwards until the mixture is covered.
Roll the wrapper starting from the bottom to the top. Dip your finger in egg and rub it over the tip of the wrapper to make it sticky. Set aside.
Heat oil in a pan. Once the oil gets hot enough, start to fry the fish lumpia for 2 to 3 minutes or until golden brown. Turn over to cook the other side.
Transfer to a cooling rack. Let the oil drip.
Serve with your favorite dipping sauce. Enjoy!
