Data and code underlying the publication: Accounting for spatio-temporal distribution changes in size-structured abundance estimates for a data-limited stock of Raja clavata

This Repository consists of processed data and code to reproduce the analyses (model fitting, prediction and sampling from the posterior of the best model) for the associated article: 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.
