Let’s get to the root of what is going on.The Mechaber in Shulchan Oruch Yoreh Deah 84/16 States that “all” worms found in fish; in the stomach are ossur, and in the flesh or between the skin and the flesh are mutar. It is accepted since the gemoras time(that means from Kabolas Hatorah)That the worms in the fish flesh is kosher.
Look in Rav Moshe Vai’s sefer and you will see the impressive list of Poskim that ruled that the worms are kosher.
