In this note, we consider the large time behavior of following chemotaxis-Navier-Stokes system$ \begin{equation*} \label{AH4} \left\{ \begin{split} n_t + {\bf u}\cdot\nabla n & = \Delta n^m - \nabla \cdot\big(n\nabla c\big), \qquad x\in\Omega ,\, t>0,\\ c_t c nc, &\qquad u}_t u} \Delta{\bf +\nabla P n\nabla \phi, \cdot{\bf 0, t>0 \end{split} \right. \end{equation*} $with $ m>1 ...
