Effect of algal blooms due to trophic interaction: A qualitative study

In this paper, we consider a mathematical model of an outbreaks that links the trophic structure of primary and secondary producer in the estuary. Although the environmental and meteorological factors are cosidered to be exogenously induced physical factors that unleashed the bloom, but ensuing duration and severity of an outbreak are largely due to the subsequent biological interplay between organisms. We give results that are qualitatively resemble with those observed in the estuary and thereby offers an insight for the factors that sustain a bloom.
