I buy it fresh at the seafood counter...it doesn't come in any packaging. But I will look for some rainbow trout...or steelhead...I did find some of that before, but I haven't been able to find any recently. I don't know much about silversides...where can I buy safe silversides? I have often thought of trying them. I do see smelt at the seafood counter and know that some people use that...smelt is safe right? Any guidelines for buying that?
