The biological reserve of Massa, situated in the National
Park of Souss Massa, certified Ramsar has a global interest
in birdlife. The functioning of the lagoon is affected by
the problems of eutrophication, declining water levels, lack
of communication with the sea. This work represents a first
contribution to the study of the plankton community living
in the lagoon of this reserve in connection with the
physical chemistry of water. The analysis of the
physico-chemical and biological state shows a very advanced
eutrophic water of the lagoon, characterized by high levels
of orthophosphate and chlorophyll a. The structure of
zooplankton populations is characterized by the dominance of
species of eutrophic environments and tolerates changes in
salinity.
Key words: Reserve of Massa, eutrophication, zooplankton, lagoon,
physico-chemical.
