Assessment Model
Methodology
Scientific basisData and methods Information on landings by Division or Subarea (Figure 9.4.14.1) and sporadic cpue information is available (see Figures 9.4.14.2 and 9.4.14.3), though not from the major fishing grounds. No analytical assessment was carried out. Provisional biomass estimates were derived from an acoustic survey in Subarea VII. However, the precision of these estimates was low.
Summaries of the total landings for all areas are given in Table 9.4.14.2. Landings by Subarea and by nation are given in Table 9.4.14.1.
Information from the fishing industry Results from a cooperative project between the French industry and IFREMER indicate that there is no discarding of orange roughy by French deep-sea trawlers in Subareas VI and VII.
Comparison with previous assessment and adviceThe perception of the state of orange roughy spawning aggregations in Subarea VI and VII as depleted and vulnerable remains unchanged since 2006. The 2008 advice remains unchanged from 2006.
Overall Assessment Results

Figure 9.4.14.1. ICES estimates of international catch of orange roughy. a) areas cumulative, b) per area separately.  |
 |
Figure 9.4.14.2. Cpue from French trawlers in Subarea VIa for 400–600 kW power vessels (open triangles) and for 1400–1600 kW vessels (solid squares). The line is a smooth curve through the latter series.  |

Figure 9.4.14.3. Cpue from French trawlers in Subarea VII. Cpue series for 400–600 kW power vessels (open triangles) and for 1400–1600 kW vessels (solid squares). The line is a smooth curve through the latter series, excluding the high 1997 point.  |

Scientific Advice
Single-stock exploitation boundariesDue to its very low productivity, orange roughy can only sustain very low rates of exploitation. Currently, it is not possible to manage a sustainable fishery for this species. ICES recommends no directed fisheries for this species. Bycatches in mixed fisheries should be as low as possible.
