This is that streamer fly. Have caught salmon, steelhead, trout, serf perch, sea bass, ling cod, green ling, cabezon and some other salt fish on it that I never identified. I imagine if it was down sized it would catch Bass, crappie and maybe gills and perch. Looks like a minnow but the colors are reverse, the dark runs on the bottom and point down.

If it catches crappie, bass and other panfish like it does other fish I would be simply over run with them. Put 37 salmon and 102 sea bass on the bank in one day using this thing; on different days of course.
