The yields of heavy hyperons and antihyperons have been studied in deep inelastic scattering at the COMPASS experiment at CERN. The data were collected in 2003-2004 using a 160 GeV polarised muon beam scattered off a large polarised 6LiD target. Signals from Σ+(1385), Σ−(1385), Ξ−(1321) and their antiparticles were reconstructed. The ratios of Σ±/Λ, Σ±/ Λ, Ξ−/Λ and Ξ+/ Λ were determined. These ratios were used to tune parameters of the LEPTO generator. Comparison with the yields of the heavy hyperons at low Q2 - region was done.
