Location of the sampling stations considered in the analyzes from IPMA's Phytoplankton Laboratory included in the National Bivalve Molluscs Monitoring System.

Within Portugal's National Biological Sampling Project (PNAB) a set of activities are conducted in the collection, management and use of biological data, collected from the registered commercial fleet in mainland Portugal (fisheries-dependent data) and several research surveys (independent fisheries data). These activities allow the assessment of the state of fishery resources, population structure, distribution and abundance of resources, diversity and dynamics of biological communities associated with the fishery resources and biological studies (growth, reproduction).This resource shows the geographic distribution of blackbelly rosefish abundancy index (nr. individuals/hour) registered during the CRUSTACEOS2014 campaign in June 2014.

The current artificial reefs were deployed, starting with a pilot project in 1990, in order to serve as instrument for the revitalization of coastal ecosystems, planning of coastal fisheries and integrated coastal zone management. Each reef is composed by, at least, 2940 concrete modules with a weight of 3 tons and 36 large modules with more than 40 tons each. The reef complex groups 20,748 modules (with a total volume of over 100,000 m3), occupying discontinuously a total area of approximately 43.5 km2, with an area of influence greater than 67 km2.

The Nazaré Artificial Reef deployed in 2010, covering an area of apr. 3 Km2 was a public project commissioned by the Nazaré Council, with the technical and scientific support of the multidisplinary research team from IPMA.
