Welcome to cheftalk.
Well my friend, I hope that your haddack does not have a smell other then the ocean. haddack, Like Cod,scrod and Hake should have a firm flesh,Very white, with no off oder.
If it does,Bring it back...If it's to late,pop it in the freezer and return it to where you found it
PS, There is no room for oFF seafood
