Russ,
That sounds like a great idea. We have some
Relative Weight Charts here in the archives. Chart 1 of 3 has black crappie. Unfortunately, I don't think it will do you any good for a little while. The charts are more for fish that people would be catching and not releasing.
Anyway, please keep us informed. I really like the approach. I've tried a number of different kinds of fish in cages that just weren't interested in pellets.
Regards,
Ken
