BB fish suffer from rougher handling and long waits at the processor...
Copper River fish, especially early in the run, are babied to maintain the image as the best. They also mostly run farther and start with more good fat.
The difference is small, but Copper or Kenai (second run) are the best IMO.
The reds that we got from my wifes co-worker came straight from his boat and didn't go to a processor, if that makes any difference.
