Every fall when we do net samples we end up with both Black and white in several impoundments and after sorting many 1000's of both, it's easiest to say you just get an eye for it.
Most of what we sort are 100mm class and slightly larger and once in awhile we end up mixing a few blacks and whites but when sampling it's not a huge deal versus stocking them, but there is a distinct difference in crappie vs sunfish in body thickness. Directly behind the eye, the crappie are very thin compared to (other) sunfish.
