A study of strange particle production in nu(mu) charged cur-rent interactions has been performed using the data from the NOMAD experiment. Yields of neutral strange particles (K-S(0), Lambda, (&ULambda;) over bar) have been measured. Mean multiplicities are reported as a function of the event kinematic variables E-nu W-2 and Q(2) as well as of the variables describing particle behaviour within a hadronic jet: x(F), z and p(T)(2). Decays of resonances and heavy hyperons with identified K, and A in the final state have been analyzed. Clear signals corresponding to K*+/-, Sigma(*+/-), Xi(-) and Sigma(0) have been observed.
