摘要:In this paper, by applying Mawhin’s continuation theorem of coincidence degree theory, we consider the following fishing model with harvesting term and obtain some new sufficient conditions for the existence of at least two positive almost periodic solutions for the model. In addition, the local asymptotical stability of the model is also discussed. An example is employed to illustrate the result in this paper.
