Marine Biodiversity in the Journal of Cadiz

How much biodiversity is in the Gulf of Cadiz ? To this question, scientists can not give a specific answer, or indeed, accurate. There have been some advances very substantial in various habitats and ecosystems, particularly those located in the coastal domain (inter-and subtidal) in the same way that we know enough about the species that live in the fishing grounds. However, this scientific information is quite biased because the method applied to obtain data. These data were obtained primarily demersal trawl gear (see photo attached) justified strategy for the operational context in which they have operated marine research campaigns that have provided the data.

The momentum that has been recently the Project INDEMARES , funded by the English Institute of Oceanography and the European Commission ( Project LIFE + ) and managed by the Biodiversity Foundation , the study of the Gulf of Cadiz, has helped increase our knowledge of particular habitats and the ecosystems that host related to the expulsion of hydrocarbon-laden fluids. The review of resource databases available on the IEO live and conduct further sampling benthic techniques have revealed the existence of a rich biodiversity that can determine a change in the management of applications being developed in some areas of the Gulf of Cadiz.

The difficulties passing the fishing industry in the Gulf, both in the fisheries of bivalves (as the case of venus, almost daily news in Diario de Cádiz) , as in crustaceans, as well as in the tuna and related species, show strong stress that the area is subjected. Not only the extraction activity the cause of this distress, as are many other activities which, presumably, are bidding farewell to biological diversity in the area, with obvious risk of destruction critical habitat. Ocean noise generated by intense vessel traffic affects many species of mammals and sea turtles, numerous submarine cables, pipes and all kinds of structures deposited on the seabed are a threat to the habitats that are extremely sensitive to these activities ... etc, are, together, a real pressure on ecosystems that degrade the marine environment.

say at this stage of life that the marine environment and biodiversity are essential to the development of life on Earth, is obvious, however, should remember from time to time this sort of platitudes and meditate for a while the such actions or attitudes we can take, individually or collectively, to facilitate the protection of marine ecosystems and species that live in them. We therefore ask our social role in safeguarding the species that usually do not see, simply because they inhabit the sea floor, and that when we are above the market stalls or in the seafood. So do not think the trail of destruction they have left behind and that we help to produce if we become responsible consumers.

These issues are those discussed succinctly, the researcher Dr. Díaz-del-Rio Gemar group, in the pages of Journal Cádiz.
