The dinoflagellate Pyrodinium bahamense var. compressum has been known to be the major cause of harmful algal blooms or H.A.B. recurring in Manila Bay and other bodies of water in the Philippines. This paper proposes a system of difference equations to describe the population dynamics of the diff.erent life cycle stages of this dinoflagellate. Initial numerical results show that the model reasonably captures the population dynamics shown in nature.
