  We construct the frame-like gauge-invariant Lagrangian formulation for
massive fermionic arbitrary spin fields in three-dimensional $AdS$ space. The
Lagrangian and complete set of gauge transformations are obtained. We also
develop the formalism of gauge-invariant curvatures for the massive theory
under consideration and show how the Lagrangian is formulated in their terms.
The massive spin-5/2 field is discussed as an example.
