New ICES stock in 2022:  

Based on analyses carried out for WKELASMO and a genetic analysis, it was concluded that thornback ray in divisions 8.abd and thornback ray in Division 8.c (Cantabrian sea) are demographically independent, with only minor flow of individuals. There is further a meta-population structure within the assessment unit 8.abd but assessment at a higher spatial resolution is not practically achievable.
