We present the results of experimental work aimed at examining the feasibility of controlling the growth of desirable species on man-made coastal defense structures (CDS). We focused on important habitat forming macroalgae of the genus Cystoseira threatened by loss in the Mediterranean sea. We analyzed the role of grazing in influencing the survival and growth of Cystoseira on CDS, as pilot tests suggested herbivory has a potentially limiting role. Grazers impact on growth and survival of...

In this communication, the composition and structure of macrofaunal assemblages in sandy beaches of the SW Spanish coast is studied. Ten beaches along the western coast of Andalucía were sampled, from Isla Canela (Ayamonte-Huelva), near to the Portuguese border, to the Strait of Gibraltar.

With ca. 27.000m3 of submerged structures by 25-30m depth, the "PRADO REEFS" programme initiated in 2008 in the bay of Marseille, is one of the largest artificial reefs complex in Europe. Structures were established close to Posidonia oceanica meadows, a highly productive ecosystem, heavily impacted in this urban area. This 6M€ programme has emerged after concertation with all stakeholders.

Data gathered between 2001 and 2005 by the Instituto de Pesca de São Paulo show the main species captured in marine fisheries in the state of São Paulo. Based on this list, a survey was carried out regarding the vulnerability of these species using national and international databases, such as IUCN, Greenpeace, Instituto de Pesca de São Paulo, IBAMA and the state of São Paulo Decree No. 56,031, 20th July 2010.

Chlorophyll a. concentration, water temperature, photon in the water and other related parameters were observed every 10 minutes during 16 days in Yodo River estuary in Japan.  Cell density of each species of phytoplankton and nutrient concentrations were also observed every two or three days.
