The cpue series that is used as the basis for advice is derived from trips where blue ling accounts for more than 10% of the total catch (Figure 22.214.171.124.1).
Two trawl surveys are available (Figure 126.96.36.199.3). The spring survey does not cover the full depth range of blue ling and is considered inappropriate. The autumn survey does cover the full depth range, but the time-series is too short to contain a useful signal and available information indicated stability in recent years.
Landings dataseries have been extended back in time to include data not previously presented (Figure 188.8.131.52.2 and Table 184.108.40.206.1).Comparison with previous assessment and advice
There are no changes to the perception of the status of blue ling in Subdivisions Va and XIV. The current advice is in line with previous advice.
