Precision measurements of hyperon-antihyperon production with antiprotons permit detailed tests of strange quark pair production and decay. Recent measurements at LEAR of lambda-antilambda production are compared with selected calculations. A recent search in the K/sub s/K/sub s/ channel for xi(2230) formation and possible future searches for CP nonconservation in the lambda-antilambda system are also discussed. 17 refs., 13 figs.
