From the Star K website:
“Some Gedolei Eretz Yisroel have ruled that these worms are halachically prohibited and, therefore, those species of fish must be inspected prior to use.
Since we at Star-K strive to have our kosher certified products accepted by all kosher consumers, Rabbi Moshe Heinemann has instructed Star-K establishments and mashgichim that only the non-problematic fish be used.”
Rav Heinemann is not saying at this time that the fish are assur, only that he wants his hashgacha to be accepted without qualification by everyone and therefore only permitted this list of fish in his food establishments.
