1. Análise ecológica e econômica da pesca marinha por meio de indicadores multiespecíficos / Ecological-economics analysis of marine fishery with multispecies indicators
Changes in marine ecosystems and fisheries resources due to the fishing pressure can be detected by multispecies indicators. These are, usually, applied to catch or landing time series, jointly the resources bio-ecological data. However, there is an alternative approach, based on market data that could be used.

Many experimental studies contributed for the development of the theory of the lacustrine food web, disclosing the important paper of the fish, for decades ignored by the limnology. These studies, in its majority, had been developed in Europe and North America and the generality of the hypotheses supporting the theory was not tested yet in subtropical and tr
