About $10^{6}$--$10^8$ hyperons, i.e., $\\Lambda$, $\\Sigma$, $\\Xi$, and $\\Omega$, will be produced in the $J/\\psi$ and $\\psi(2S)$ decays with the proposed data samples at BESIII. Based on these samples, the measurement sensitivity of the branching fractions of the hyperon decays is in the range of $10^{-5}$--$10^{-8}$.
