Bob says there used to be crappie fish AN D bass in the lagoon near his house (south side Chicago, Illinois), and they asre definitely two different fish. The bass is nice and solid and cooks up nice; the crappie is softer and less pleasant. Bass are somewhast larger than crappies (which he promounced "crappie" but was not unfamiliar with the "croppie" pronounciation.
Said the city would stock the lagoon with these fish every spring, and what were not caught would die off during the cold of the winter.
