  The fragment production in collisions of $^{48,50}$Ca+$^{12}$C at 50
MeV/nucleon are simulated via the Isospin-Dependent Quantum Molecular Dynamics
(IQMD) model followed by the {GEMINI code}. {By changing the diffuseness
parameter of neutron density distribution to obtain different neutron skin
size, the effects of neutron skin thickness (${\delta}_{np}$) on
projectile-like fragments (PLF) are investigated. The sensitivity of isoscaling
behavior to neutron skin size is studied, from which it is found that the
isoscaling parameter $\alpha$ has a linear dependence on ${\delta}_{np}$. A
linear dependence between ${\delta}_{np}$ and the mean $N/Z$ [N(Z) is
neutron(proton) number] of PLF is obtained as well.} The results show that
thicker neutron skin will lead to smaller {isoscaling parameter} $\alpha$ and
N/Z. Therefore, it may be probable to extract information of neutron skin
thickness from {isoscaling parameter} $\alpha$ and N/Z.
