Data collection is a fundamental aspect of the Common Fisheries Policy (CFP). It provides the information required to develop scientific guidance on how to manage the fishery resources exploited by European fleets. The European framework that regulates this data collection is called the DCMAP- Data Collection Multi-Annual Plan (Executive Decision 2016/1251 of the Commission and Regulation 2017/1004 of the European Parliament and of the Council).

AZTI is responsible for collecting data on the status of marine resource exploitation and the marine ecosystem in relation to Basque fleets and fish landings made at Basque ports. In order to respond to the obligations set out by the DCMAP, AZTI’s programme of work includes:

  • Sampling variables at ports and offshore (catches, effort, etc.) for commercial fishing, including the information collected by the fisheries sector (fishing logbooks, first sale notes, etc.).
  • Sampling of biological parameters of species (size, weight, age, sex, maturity).
  • Carrying out scientific campaigns at sea.
  • Sampling recreational fishing.
  • Analysing all the information collected and setting out annual sampling plans.
  • Sampling coordination nationally and internationally.
  • Preparing basic information for international stock assessment working groups (catch matrices by size, age, etc.).
