Abstract

Podamo, J. (1975). Ecometabolism of a shallow marine lagoon at Ostend (Belgium) : 2. Zooplankton dynamics. 10th Europ. Symp. Mar. Biol. 2: 501-515

The food chain of plankton at the Sluice-Dock is reduced to the simple system "producers-primary consumers". The role of zooplankton is most important only for a short time, namely in May, when it restricts the development of phytoplankton by its grazing activity, and becomes the main source of nutrients due to its excretory activity. After the disappearance of most of the zooplankton biomasses, caused by a mortality that is not due to predation, the phytoplankton can again develop. At other times of the year, the zooplankton activities such as production, grazing, excretion, and respiration only represent 1% of the total plankton activity.
