The gorgònies, the corals and the sponges at shrinking owed at the ploriferació of algae filamentoses
The last years is observing a proliferation of algae filamentoses, increasingly durable, affecting at marine communities sèssils like the gorgònies, coral, sponges and briozous. However, the presence of the algae recobrint the seabed and his marine communities, makes that it lessen the tourist appeal of the seabed and that the rank of indulgence was not the expected. Besides, everything seems to signify that the massive presence of these algae filamentoses can affect of negative form at the activity pesquera traditional that develops at the zone.
These trainings of algae take the common name of llepó and, generally, are formed by species of dark-haired algae and can being Acinetospora crinita, Nematochrysopsis marine, Zosterocarpus oedogonium and Chrysonephos lewisii.
At general lines, these algae proliferate at the beginning of the spring, when the water of the sea commences at increasing his temperature and the storms of wind and of sea are less frequent, but with the climatic change these masters are viewing altered. Besides, determinate scientific surveys signify that these proliferations algals can view favoured by the eutrophication of the water as a consequence of determinate acts of anthropic origin like the agricultural activities.
How it influences the quality of the water at this proliferation?
For everything this, this year will induct a pilot project of control of algae filamentoses at the islands Medes, furthered by the Natural Park of the Montgrí, the islands Medes and the Low Ter and Girona's University, with the collaboration of the centres of dip of the Estartit, with the aim to study at depth this problematic.
At the frame of the project Life eCOadapt50 has decided collaborate at this survey leaning at the analysis of the quality of the seawater of the bay of Masts and the Islands Medes, fundamental to be able to establish an account with the ploriferació of the algae filamentoses. However, the collaboration also includes the realisation of several communicative campaigns focused at conscienciar and sensitise on this problematic.
