Very low risk
The status of the pollack stock in the Celtic Sea and West of Scotland (Sub-areas Vl and Vll) has been scored a high risk. This is because the species has moderate resilience to fishing exploitation (FishBase, 2015), but the population trend is unknown due to the limited information available for this data-limited stock. Available data are limited and additional information is required to evaluate the status of the stock with a high degree of confidence.
The management of pollack in the Celtic Sea and West of Scotland (Sub-areas Vl and Vll) has been scored a low risk. This is because management decisions are informed by an annual stock assessment, catches of pollack have been below the available TAC over the last decade, and a comprehensive regulatory framework has been put in place. Data-limited approaches are used for setting management controls, which are based on knowledge of the fisheries and the biology of the stock. However, the agreed TAC is substantially higher than the recommended catches and does not limit fishing opportunities.
The bycatch risk of this fishery has been scored a very low risk. This is because handlines and pole-lines are a highly selective form of fishing gear used to target particular species in areas where fish are known to congregate. In addition, discarding of pollack is considered to be negligible at 0.5% of total international catch weight in 2014 (ICES, 2015). Handlines are unlikely to take bycatches of non-target species and the incidental capture of protected, endangered and threatened (PET) species (e.g. sharks, rays and sea turtles) is rare.

The habitat risk of this fishery has been scored a very low risk. This is because handlines and pole-lines have no interaction with the seabed and some spatial management has been established to protect vulnerable marine habitats from fishing activities.
