I made carp caviar (AKA tarama) from silver carp roe one time. I think mine was as good as the common carp tarama I tried years later. A flavor that kind of sticks with you, though. The canned common carp roe was really fishy, I thought. Not terrible, but I wouldn't pay money for it. I used a common carp tarama recipe from the web on silver carp, and it was not nearly as salty and fishy as the canned stuff, but I would not pay money for that, either. I'd eat either if I was hungry and there was nothing else really yummy around, though.
