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).The spring acoustic surveys are usually held in April/May with the ship "Noruega" and cover the Portuguese continental waters and the Spanish waters of the Gulf of Cadiz, between 20 and 200m deep.

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.

Marine biotoxins monitoring of bivalve molluscs in classified production areas in mainland Portugal, since 2014, at intervals defined in the respective sampling plan, through the detection and quantification of the various groups of marine biotoxins laid down in Regulation (EC) 853 / 2004 in live bivalve tissues. These analyzes are part of the national monitoring of bivalve molluscs production areas and are considered in the official control system for decision-making concerning health rules applicable to bivalve in the various production areas. The data is collected according to the requirements of Regulation (EC) No 854/2004 of the European Parliament and of the Council of 29 April 2004 and the rules set out in Decree No. 1421/2006 of the Ministries of Economy and Innovation and Agriculture, Rural Development and Fisheries of 21 December 2006.
