Abstract

Here I want to focus on the environmental management of coastal shallow water, eutrophic areas, such as lagoons, estuaries and brackish lakes. It is now about fifty years that, everywhere in the world, these coastal areas are strongly eutrophic or hypertrophic. They are subject to microorganisms and/or macroalgal blooms, and, periodically, to dystrophic crises, which destroy the benthos communities and can penalize the fishing and tourism economies with die-off of commercial fish species, and stench.
