A trophic web is a network of complex interactions and energy links between species. These can be simplified into trophodynamic models, such as Ecopath (EP) EcoTroph (ET), important tools providing the holistic view needed for ecosystem approach to fisheries. We described food structure by developing an EP model Santa Cruz Channel (SCC), large tropical estuarine system in northeastern Brazil, s...

The past decade has seen the implementation of conservation and fisheries management strategies to reduce the impact of the ECOTF on the seabed and improve biodiversity conservation.

VMSbase is an R package devised to manage, process and visualize information about fishing vessels activity (provided by the vessel monitoring system--VMS) and catches/landings (as reported in the logbooks). VMSbase is primarily conceived to be user-friendly; to this end, a suite of state-of-the-art analyses is accessible via a graphical interface. In addition, the package uses a database platf...
