  The effects of the anisotropy on the fluid pulsation modes adopting the
so-called Cowling approximation and tidal deformability of strange quark stars
are investigated by using the numerical integration of the hydrostatic
equilibrium, nonradial oscillations, and tidal deformability equations, being
these equations modified from their standard form to include the anisotropic
effects. The fluid matter inside the compact stars is described by the MIT bag
model equation of state. For the anisotropy profile, we consider a local
anisotropy that is both regular at the center and null at the star's surface.
We find that the effect of the anisotropy is reflected in the fluid pulsation
modes and tidal deformability. Finally, we analyze the correlation between the
tidal deformability of the GW$170817$ event with the anisotropy.
