Raja clavata and Scyliorhinus canicula abundance dataset supporting the 2024 Belgian MSFD assessment of D1C2

This dataset is part of the 2024 Belgian submission for the Marine Strategy Framework Directive (MSFD) linked to descriptor 1, criterion 2. It originates from the ICES DATRAS (Database of Trawl Surveys), which compiles standardised bottom trawl survey data collected from various European waters; for this indicator, the Belgian Beam Trawl Survey (BTS) data from the North Sea were used. The dataset includes species abundance, length and age distributions, catch per unit effort, and environmental parameters, providing key insights on the population abundance of thornback ray (Raja clavata) and lesser-spotted dogfish (Scyliorhinus canicula) for stock assessment and fisheries management.

Statement: Data are collected following ICES standardized protocols, including calibration of trawl gear, data validation, and quality control checks (ISO17025-based national QC standard). 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. Data is collected under national and international fisheries research programs coordinated by ICES member countries. The Belgian Beam Trawl Survey (BTS) is funded under the National Data Gathering Program. The BTS has been conducted annually since 1993 (continuous time series; the survey itself started in 1992). Bottom trawl (4m beam trawl, 40mm cod-end mesh). Measurement boards for fish length (in-house SmartFish measuring board), environmental sensors, data-entry systems (Smartfish database).
