Studies have consistently shown that Stripers overwhelmingly prefer soft-finned baits (herring, shad, etc). That's not to say the occasional crappie or Bass or bream is not consumed by a big Striper, but realize it is rare. Stripers also help consume the larger herring and shad, which keeps the average bait fish size smaller, which usually makes them more useable by smaller game fishes (crappie, bass, etc). So in most cases Stripers are beneficial to the other popular game fish. I think the others hit the nail on the head with the White Perch. They essentially are direct competitors with the crappie. I know I catch many a white perch while crappie fishing on other lakes. I fished Murray last month in the big Striper tourney held out Dreher Island on 12/9. One thing many of the competitors commented on was the abundance of small white perch. Many times a bait ball looked like shad, but when a net was thrown on it, hundreds of small white perch were the culprit. My two cents.
