Abstract: 

 

In this paper, the model deals with competition in populations which diffuse in a circular bounded area. Migration of interacting marine animal species in ocean is considered. Pseudo Analytic Finite Partition Method (PAFPM) has been employed to find out the approximate solution of the dispersion problem in the non-homogeneous region. A two dimensional circular region is considered. For angular direction the Fourier series has been used assuming angular uniformity in each part. After numerical verification graphs are plotted between  the angle  and population density of species for constant time.
