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.

Nosologic map of the Pacific Cupped Oyster in mainland Portugal. The health screening of the species population aims the identification and characterization of diseases affecting the Pacific Cupped Oyster and their characterization both as to its epidemiology (incidence, prevalence and intensity of the disease), as to their impact on production. This information is intended to characterize the different production areas of the species from the health point of view.

Delimitation and classification of coastal and estuarine-lagoon areas of molluscs and bivalve production located in the mainland published by Diário da República (the Portuguese Official Gazette) Nº. 78/2015, 2nd series of 2015-04-22, Order Nº. 4022/2015. To check the status of classification and / or the most current bans associated with the areas it is recommended to consult the IPMA page dedicated to the matter from 'http://www.ipma.pt/en/pescas/bivalves'.

Microbiological monitoring of bivalve mollusc production areas in mainland Portugal, since the year 2014, performed by quantification of Escherichia coli in meat and liquid intravalvular live bivalve, according to the sample planning. These analyzes are part of the National monitoring system of bivalve mollusc production areas and are considered in the classification of these areas and in the decision-making relative to their status. The data is collected according to the 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.

Identification and enumeration of harmful and potentially toxic phytoplankton species from water samples collected weekly in shellfish production areas, coastal and transition in mainland Portugal since the year 2014. These analyzes are part of the national system of monitoring bivalve mollusc production areas of IPMA and are considered in the zoning and in making decisions regarding their status. The data is collected for the requirements of Regulation (EC) No 854/2004 of the European Parliament and of the Council of 29 April 2004.
