  By a work of Thurston, it is known that if a hyperbolic fibred $3$-manifold
$M$ has Betti number greater than 1, then $M$ admits infinitely many distinct
fibrations. For any fibration $\omega$ on a hyperbolic $3$-manifold $M$, the
number of fibrations on $M$ that are commensurable in the sense of
Calegari-Sun-Wang to $\omega$ is known to be finite. In this paper, we prove
that the number can be arbitrarily large.
