Summaries of the total landings for all areas and by Subarea are given in Table 184.108.40.206 and Figure 220.127.116.11. Landings by Subarea and by nation are given in Tables 18.104.22.168 and 22.214.171.124.
French trawl cpue and Portuguese longline cpue data series are presented in Figures 126.96.36.199 and 188.8.131.52.
The abundance index from the commercial fishery is derived from directed lpues of a French reference fleet in a reference area from trips where black scabbardfish comprises more than 10% of the total landings. The reference consists of large high-sea trawlers (>45 m overall length) that were already fishing in the early 1990s. The number of vessels in the reference fleet have declined over the years and the mean age of the vessels has increased. Several factors (month, depth, rectangle, vessel, skipper) are shown to have explanatory power on cpue, but they are not included in the calculation of the cpue.
Black scabbardfish is not known to be discarded; this implies that lpues are equivalent to cpues for this species.Information from the fishing industry
In collaboration with the French industry, IFREMER has carried out investigations to refine the cpue series for French trawlers. A new time-series based on haul-by-haul data was initiated by the French industry, but this series only goes back to 2000. It shows that 72% of the hauls dedicated to deep-sea fisheries catch black scabbardfish at depths between 700 and 1300 m. The ‘deep-sea’ hauls (28%) where no black scabbardfish are reported are at lower (500–800 m) or deeper depths (1300–1400 m).
Information collected under the French deep-water sampling programme indicates that there are no discards of this species in the French trawl fishery. Comparison with previous assessment and advice
There is no change in the perception of black scabbardfish. Due to the persistent decline in cpue in Areas Vb, VI, VII, and XII, ICES recommends further reduction in catches compared to the previous advice.
