Abstract: This paper studies the dynamics of a plankton‐fish system with three delays. First, we prove the positivity and boundedness of solutions. Then, under three cases: one delay, two delays, and three delays, we discuss the influence of multiple delays on the dynamics by theoretical analysis and simulation. At last, in absence and presence of delays, we give the influence of fear effect on the dynamics by simulations. Our results reveal that both delays and fear effect bring rich dynamics for plankton‐fish system, such as periodic oscillation and chaos. [ABSTRACT FROM AUTHOR]
