A gauge-invariant reformulation of QCD in three spacetime dimensions ispresented within a Hamiltonian formalism, extending previous work to includefermion fields in the adjoint and fundamental representations. A priori thereare several ways to define the gauge-invariant versions of the fermions; aconsistent prescription for choosing the fermionic variables is presented. Thefermionic contribution to the volume element of the gauge orbit space and thegluonic mass-gap is computed exactly and this contribution is shown to beclosely related to the mechanism for induction of Chern-Simons terms byparity-odd fermions. The consistency of the Hamiltonian scheme with knownresults on index theorems, Landau Levels and renormalization of Chern-Simonslevel numbers is shown in detail. We also comment on the fermionic contributionto the volume element in relation to issues of confinement and screening.
