Strange and charmed baryon productions from proton-antiproton collisions arestudied in the effective Lagrangian and Regge approaches. We include only the$t$-channel dynamics which is dominant for the diffractive region that isrelevant in the present discussions. For strangeness productions, the couplingconstants for $K$ meson are determined by $SU(3)$ relations while other unknownparameters for $K^{*}$ couplings and for form factors are fixed by existingobserved data for strangeness productions. By extrapolating the amplitudes forstrangeness productions to those for charm, we predict charm production crosssections. It turns out that the total cross sections are $10^{4}$ to $10^{5}$smaller than those of strangeness productions, depending on the final states.By using the known total cross sections for strangeness, $\sim 10^{2} \mu b$for $\Lambda \bar{\Lambda}$ and, $\sim 10^{1} \mu b$ for $\Sigma \bar{\Lambda}$the total cross sections for charm productions are predicted to be $\sim10^{-2} \mu b$ for $\Lambda_{c} \bar{\Lambda}_c$, $\sim 10^{-3} \mu b$ for$\Sigma_{c} \bar{\Lambda}_c$, and $\sim 10^{-4} \mu b$ for $\Sigma_{c}\bar{\Sigma}_c$. Our results can be tested in the future experiments at$\bar{\text{P}}$ANDA.
