Accounting for spatio-temporal distribution changes in size-structured abundance estimates for a data-limited stock of Raja clavata
DOI : https://doi.org/10.1093/icesjms/fsae106
Research-vessel catch data for the North Sea and Eastern English Channel was obtained from ICES database on trawl surveys (DATRAS) for Raja clavata (WoRMS AphiaID: 105883) and processed to create a final dataset for spatio-temporal analysis with integrated-nested laplace approximation (INLA). The final processed dataset consists of hauls and catches from the International Bottom Trawl Survey (NS-IBTS) for Quarter 1 and 3, the Beam Trawl Survey (NS-BTS) for Quarter 3, and the Channel Groundfish Survey (FR-CGFS) for Quarter 4. It further contains depth, substrate and habitat types associated with haul locations obtained from emodnet for the study area. The data and analyzes covers the period 1988-2023.
