Frequency dependence of χ"(T), different position of a maximum in χ"(T) for different crystal orientations, hysteretic behavior between magnetization measurements in zero-field cooling and field coolding regime are attributed to strong magneto-crystalline anisotropy of PrNi ferromagnetic single crystal with T_C=20.5 K, which is driven by crystal field effect. Applied pressure shifts T_C to higher temperatures (dT_C/dp=1 K/GPa). Susceptibility follows the Curie-Weiss law except for b-axis, which is hard magnetic axis. An anisotropic behavior was seen in resistivity measurements with the largest difference between b-axis and c-axis. Resistivity below T_C can be described by power law with ρT^{2.24} and is field dependent with a positive magnetoresistance.
