  We propose a means to detect the nucleon strange quark-antiquark asymmetry,
which is predicted as a non-perturbative effect, but still unchecked directly
by available experiments. The difference for the $D(c\bar{q})$ and
$\bar{D}(\bar{c}q)$ meson production cross sections in neutrino and
antineutrino induced charged current deep inelastic scattering is illustrated
to be sensitive to the nucleon strange asymmetry. Prospect is given and the
effect due to the light quark fragmentation is also discussed for the
extraction of the strange asymmetry in future experiments.
