5. Length-based estimates of growth parameters and mortality rates of fish populations from a coastal zone in the Southeastern Brazil
ABSTRACT Small-scale fisheries in Brazil contribute to a significant share of total fish production, accessing a large variety of species. Life history parameters from these resources are important for their management and conservation, based on primary data. The objective of this article is to generate growth parameters and mortality rates of ten fish popul

8. 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. In this study, several multispecies indicators
