The production at central rapidity of KS0, Lambda, Teta and Omega particles in Pb-Pb collisions at 158 AGeV has been measured by the NA57 experiment over a centrality range corresponding to the most central 53% of the inelastic Pb-Pb cross section. We present the rapidity distribution of each particle in the central rapidity unit. The distributions are analysed based on hydrodynamical models of the collisions.
