  We demonstrate explicitly the correspondence between all protected operators
in a 2+1 dimensional non-supersymmetric bosonization duality in the
non-relativistic limit. Roughly speaking we consider $SU(N)$ Chern-Simons field
theory at level $k$ with $N_f$ flavours of fundamental boson, and match its
chiral sector to that of a $SU(k)$ theory at level $N$ with $N_f$ fundamental
fermions. We present the matching at the level of indices and individual
operators, seeing the mechanism of failure for $N_f > N$, and point out that
the non-relativistic setting is a particularly friendly setting for studying
interesting questions about such dualities.
