This bibliographical study falls under the context of researching financial autonomy for durable management of South countries' wastewater ponds (WSP), and growing interest on shellfish zooplanktons that contribute to water treatment and can be recovered in aquaculture and many industrial applications. Our project will start by gathering available data aiming at the development of a mathematical model of the contribution of zooplankton in pond ecosystems. This model would include the effect of most driving factors on the growth of shellfish zooplankton in WSP combined with water treatment efficiency and biomass productivities. After a description of various types of WSP and their corresponding zooplanktons, emphasis is put on the shellfish cladocerans, especially Daphnia. The range of growth rates in various conditions is provided and expressions of growth kinetic, merging the effect of most important factors identified. These expressions of kinetic and the corresponding stoichiometry will serve as a first approach in our model. We hope that this type of research will help in the development of sustainable sanitation systems in developing counties.
