Description 
Summary

The objective of this project is to study the ecology of the planktonic phases of fishes, crustaceans and molluscs of Ria de Aveiro. Their temporal and spatial dynamics (e.g. abundance, distribution, tidal transport, retention areas, predation, food availability) were studied in detail with special attention on the study of the influence of tidal, diel and lunar cycles to the abundances and strategies of behaviour of zooplankton. The project was carried out in different phases. Firstly the planktonic phases of a certain number of target species of biological or economical importance were characterized. Secondly using different sampling designs, the ecological factors (biotic and abiotic) known to affect recruitment were studied in detail.
