  We extend to the strange quarks and antiquarks, the statistical approach of
parton distributions and we calculate the strange quark asymmetry $s-\bar s$.
We find that the asymmetry is small, positive in the low $x$ region and
negative in the high $x$ region. In this framework, the polarized strange
quarks and antiquarks distributions, which are obtained simultaneously, are
found to be both negative for all $x$ values.
