During the secondment, we worked on the trophic structure of some estuarine and coastal ecosystems in Pernambuco (WP2). The main aims of the secondment were to analyse the results of stable isotopes analysis and to begin the building of trophic models and to write publications.

In details we worked on plankton size spectra and stable isotopes composition, on cross shelf connectivity of some major fish species (Eucinostomus argenteus, Caranx sp. and some Haemulide sp.) based on the trophic ecology of mesopelagic fishes, on bioaccumation of some contaminants through the food web, on the trophic modelling with EwE models of an estuary and finally on the shrimps fishery in Pernambuco and its impact on the food web. These activities contribute to Task 2.4.

During this secondment we drafted or finalised the following publications:

• Soares, A., Lira, A. S., Gonzalez, J. G., Eduardo, L. N., Lucena-Frédou, F., Le Loc’h, F., Padovani Ferreira B., Frédou, T. 2020. Feeding habits and population aspects of the spotted goatfish, Pseudupeneus maculatus (Perciformes: Mullidae), on the continental shelf of northeast Brazil. Scientia Marina, 84 : 119-131. DOI : 10.3989/scimar.04958.24A

• Gonzalez, J. G., Ménard, F., Le Loc'h, F., de Andrade, H. A., Viana, A. P., Ferreira, V., Lucena-Frédou F., Lira A.S, Munaron J.-M., Frédou, T. 2019.
