dynamics, also it should facilitate the disclosure of new insights into the systems
functioning. If the lack of precise information about the artisanal fishery landings
keeps its present course, the incompatibility with the sustainability paradigm will
continuous to compromise the myriad of ecological services and living resources in
the Western Atlantic estuarine complexes.
The historical negligence of authorities in building reliable datasets for the fishery statistics in Brazil is denounced in studies regarding global (Worm et al. 2009)
and South American fisheries (Barletta et al. 2010; Reis et al. 2016). In half of all
studied ecosystems, the average exploitation of marine resources has declined globally (Worm et al. 2009). Now, figures are near or below the rate of maximum sustainable yield (Worm et al. 2009). However, the global scenario lack the input of
information on the Western South Atlantic fishery. The absence of data for Brazilian
coastal ecosystems in global compilations and analysis points to two main concerns
in national politics. The first is that, apparently, the fast growing stack of papers
containing scientific information is only a short-term tactics to provide numbers in
United Nation conferences and agreements. The second is that it reveals the inefficient communication between the academy and institutions responsible for structuring the fisheries and environmental conservation in Brazil, especially the
development of strategies to better use of estuarine and coastal marine resources.
20.6 Conclusion
Estuaries and other coastal environment of the Western Atlantic are extremely
important for providing living and non-living resources, as well as numerous ecological services, as livelihood for traditional communities. Although these services
and resources are collapsing through the years, there is strong expectations aiming
at the recovery of fish stocks and habitat restoration, especially by the scientific
community and governmental sectors. However, the majority of fishery studies
point the lack of communication between managers, governmental agencies and
scientists for building models for the management of fisheries and enviornmental
conservation as their main concerns. It is agreed that urgent attention needs to be
payed to estuaries. They provide large amounts of fishery resources (e.g. dog snapper, acoupa weakfish, mullets) to adjacent coasts and high seas in addition to their
own internal fisheries production. The semi closed characteristic of estuaries, guarantee access to high densities and biomass of important subsistence species (e.g.
prawns) and migratory fishes of commercial importance (e.g. common snook),
which are easily captured. Still, most tropical estuaries are surrounded by mangrove
forests with a diversity of habitats, and less privileged local communities target the
capture of the flooded forest fauna (e.g. uçá-crab).
Therefore, there are two main points for Western Atlantic coastal wetlands managements to take into consideration. The first is to guarantee the sustainable use of
