Statement

Data are collected following ICES standardized protocols, including calibration of trawl gear, data validation, and quality control checks. ICES applies consistency checks to ensure comparability across different surveys and years. Data undergoes post-survey validation to minimize errors in species identification, length measurements, and abundance estimates. Catch and biological data from the observer-at-sea programme are quality-checked and raised using integrated checks in the ILVO Smartfish database, PowerBI desktop and dedicated R scripts (incl. COST packages). Data is collected under national and international fisheries research programs coordinated by ICES member countries. The Belgian Beam Trawl Survey (BTS) and Demersal Young Fish Survey (DYFS) are funded under the National Data Gathering Program; the fisheries-dependent observer-at-sea sampling is carried out under the EU Common Fisheries Policy Data Collection Framework (DCF). Offshore Beam Trawl Survey: 4m beam trawl, 40mm cod-end mesh (RV Belgica); Demersal Young Fish Survey: 6m shrimp beam trawl, 22mm cod-end mesh, no tickler chains (RV Simon Stevin); observer-at-sea sampling aboard commercial beam trawlers (TBB_DEF fleet). Calculation of recruitment, fishing mortality, and spawning biomass (Rstudio); catch raising and QA in the ILVO Smartfish database and PowerBI desktop, using the in-house SmartFish electronic measuring board for biometric data capture.
