Data Collection Reference Framework (DCRF)

The Data Collection Reference Framework (DCRF) is the first comprehensive GFCM framework for the collection and transmission of fisheries-related data in the GFCM area of application (Me​dit​erranean and Black Sea). It is the result of a series of coordinated actions focused on fisheries data collection which were launched in 2013 under the umbrella of GFCM Scientific Advisory Committee (SAC) and taking into account the inputs o​f the GFCM Working Group on the Bla​ck Sea (WGBS).

The DCRF is an instrument supporting the implementation of the mid-term strategy (2017–2020) towards the sustainability of Mediterranean and Black Sea fisheries through the identification and collection of fisheries-related data necessary to improve the formulation of sound scientific advice by relevant GFCM subsidiary bodies.

The DCRF aims to be instrumental in achieving an efficient data collection programme throughout the entire region and better integrating data collection and subregional multiannual management plans. The is regular​ly reviewed by relevant GFCM subsidiary bodies in light of possible requirements emanating from the GFCM Commission, including through new recommendations.

The DCRF manual outlines the DCRF principles by encompassing all the necessary indications for the collection of fisheries data by GFCM Members and its submission to the GFCM in a standardized way, in order to empower the relevant GFCM subsidiary bodies with information needed for the formulation of advice.

The manual is composed of two main parts: Structure of data collection and Common practices in data collection. The first one was adopted by the sixteenth session of the Scientific Advisory Committee (SAC) in March 2014 and was enriched with a practical section (second part) upon the request of the thirty-eighth session of the Commission (GFCM, 2014a).

1. Structure of data collection

  • T1 - Global figures of national fisheries
  • T2 - Catch
  • T3 - Incidental catch of vulnerable species
  • T4 - Fleet
  • T5 - Effort
  • T6 - Socio-economics
  • T7 - Biological information

2. Common practices in data collection

  • Sampling overview
  • Acquisition of landing and effort data 
  • Acquisition of socio-economic data
  • Acquisition of biological data 
  • Shared stocks
  • Data quality
  • Data confidentiality and access policy
  • Data submissions

Main characteristics of the DCRF

The DCRF aims at optimizing the GFCM fisheries data collection through: 

  • clear identification of the main thematic areas of the data collection (defined as “tasks”) together with the definition of their purposes in line with the objective of the GFCM ;
  • detailed description of all the data variables;
  • simplified level of data aggregation for requested variables (in this regard, the concept of “operational units” has been superseded);
  • more flexible and easier fleet segmentation scheme; 
  • simpler measures of fishing effort;
  • new concept of priority species group whereby species are identified at the level of the five GFCM subregions (Western Mediterranean Sea, Ionian Sea, Adriatic Sea, Eastern Mediterranean Sea and Black Sea);
  • well-defined data collection practices;
  • improved online data submission procedures.
