DATRAS Netherlands Industry Survey on Turbot and Brill (NL-BSAS)
The flatfish species turbot (Scophthalmus maximus) and brill (Scophthalmus rhombus) in the North Sea are important commercial bycatches for the Dutch commercial fleet. Brill is currently a data-limited species, which is why ICES for its stock assessment uses a method based on trends in the commercial landings per unit of effort. For turbot more data are available and the advice for turbot is currently based on a full analytical assessment. Nevertheless, there is still considerable uncertainty in the input data which undermines the overall quality of the assessment. A new standardized survey with higher catch rates for large flatfish is developed to improve assessments for these species. For this reason a dedicated industry survey for turbot and brill was designed and implemented.
