Nothing wrong with them just paracites!
like already posted, cut them off and cook them up!
Took my brother out coddin last summer and because he had to get back home early , we were back at my dock by 11:00 am, so I fillet up about 20 lbs of fillets for him to take home , and headed back out with my son and got some more.
He calls me that night with the same question and I told him to cut them off, and he then tells me he allready tossed them out for the trash
Pissed me off big time!!! took he out and gave him all that fish and didn't take a dime for gas and I fed him while we were out fishing!
Haven't called him to go out since!!!
