Abstract : In this paper it is proved that on an almost coK\"ahler $3$-manifold $M$, (i) $M$ is $h$-semisymmetric, (ii) the curvature condition $Q\cdot R=0$ and (iii) $M$ is coK\"ahler are equivalent.
Keywords : almost coK\"ahler manifold, coK\"ahler manifold, $h$-semisymmetric manifold, $\phi$-symmetric manifold, semisymmetric manifold
