| Abstract: | In the study of fish population dynamics, it is a necessary tool to develop mathematical models. We have developed a new mathematical model in this paper, which is one order linear partial differential equation with variable coefficient. The new model is superior to the models obtained in the past, and can been used to estimate the numbers of different sizes in one species fish population. |

| Keywords: | Fish population dynamics Mathematical model One order linear partial differential equation |
