Abstract

Zooplankton (> 300 μm) was sampled along a large scale sampling grid off the northeast Brazilian coast from Pernambuco co Ceara State, during the dry season, from February to March, 1995. Additionally, the Iramaraca Estuarine System (IES) (near Recife, Pernambuco Seate) was chosen for a mesoscale investigation. Export of water masses from the IES was restricted to the reef line, about 6 km from the coast. In spite of chis geomorphological and hydrographical barrier, estuarine decapod larne were exported to about 15 km offshore. On the inshore shelf off Pernambuco State (6 to 15 km offshore), decapod larvae dominated in abundance and biomass. Here, the dominant decapod groups were Brachyura (lace-stage unidentified zoeae of type A, and Xamhidae), Caridea, Porcellanidae, Anomura, and Callianassidae. In the IES, the most abundant decapod taxa were: first-stage zoeae of Brachyura ( Uca spp., Ucides cordatus, Grapsidae, Xanthidae, and unidentified zoeae of type "A"), Lucifer faxoni, Upogebiidae, Caridea, Acetes americanus, and Anomura. At distances of more than 20 km off Pernambuco and at most stations off Ceara State, the zoo plankton was characterized by an oceanic copepod community. The present study confirms the importance of estuarine mangrove ecosystems as sources of food for marine food webs.
