1. Description of the fishery 1.1 Description of fishing vessels and fishing gear

Fishing for Patagonian toothfish in the SEAFO Convention Area (CA) started around 2002. Japan is the main fishing country that fished continuously for 17 years (2003-2019), while Republic of Korea, Spain and South Africa fished for some years (1-4 years). Table 1 shows the list of Patagonian toothfish bottom longline vessels and their specifications. Historically a maximum of three vessels per year fished in the SEAFO CA. The Spanish longline system and the trotline used by Japan (Fig. 1) are the fishing gears commonly used.

1.3 Reported retained catches and discards

Table 3A presents data on Patagonian toothfish catches and discards (2002-2019) listed by country, as well as fishing gear used and the management area from which catches were taken. Annual catches varied between 12t (2017) and 393t (2003). Table3B show Atlantic toothfish (Dissostichus mawsoni) catch and discards

Discards were mainly due to parasite infection of fish. In the last three years with complete data (2016, 2017 and 2018) retained catches were 60, 12 and 57t respectively and the annual weight of discarded specimens was less than 2 t in the three years period.

Retained and discarded bycatch from the Patagonian toothfish fishery are presented in Annex A. The two most important species (in terms of weight) are (GRV) and blue antimora (ANT).

1.4 IUU

IUU fishing activity in the SEAFO CA has been reported to the Secretariat in 2012 and 2015-2016. In 2015-2016 it was reported that one IUU vessel caught 92 tonnes of Patagonian toothfish.

2. Stock distribution and identity

Patagonian toothfish is a southern circumpolar, eurybathic species (70-1,600m), associated with shelves of the sub- islands usually north of 55ºS. Young stages are pelagic (North, 2002). The species occurs in the Kerguelen-Heard Ridge, islands of the Scotia Arc and the northern part of the (Hureau, 1985; DeWitt et al., 1990). This species is also known from the southern coast of Chile northward to Peru and the coast of Argentina, especially in the Patagonian area (DeWitt, 1990), and also present in Discovery and Meteor seamounts in the SE Atlantic (Figure 3) and El Cano Ridge in the South (López-Abellán and Gonzalez, 1999, López-Abellán, 2005).

In SEAFO CA the stock structure of the species is unknown. The CCAMLR Scientific Committee in 2009 noted that in most years (since 2003) the main species caught in CCAMLR sub-area 48.6 (adjacent to and directly south of SEAFO Division D) is D. eleginoides. The distribution of the species appears to be driven by the sub-Antarctic front which extends into the SEAFO CA.

3. Data available for assessments, life history parameters and other population information

3.1 Samplings

The number of fishing sets sampled from 2009 onwards (including all bottom longliners) indicates a good sampling level in line with the SEAFO preliminary guidelines for data collection (Table 4). On average, samplings were conducted in 98% of the total sets and 19 specimens were measured per sampled fishing set, which is considered acceptable given the length range of the exploited population. In future it will be necessary to apply this sampling effort of 20 individuals in all sampled fishing sets.

3.7 Feeding and trophic relationships (including species interaction) There is no available information for this species in SEAFO CA.

3.8 Tagging and migration

Eleven specimens were tagged in Subarea D in 2006 and fourteen in 2010 (Spanish flagged Viking Bay vessel). However, there is no available information on recoveries of tagged specimens or on tagged specimens tagged at adjacent areas of CCAMLR.

4. Stock assessment status There were preliminary stock assessments trials conducted during the 9th Scientific Committee meeting in 2014 (SC9 (2014) ) using assessment models such as Y/R analysis, length cohort analysis and ASPIC (production model). However, there was no consensus of agreement on results because the time series were too short and r2 (correlation coefficient) of standardized CPUE was too low (r2 < 30%). However, SC9 (2014) suggested that all results provided the perception that current harvesting rate (F) is below Fmsy in 2014 (SC9, 2014 report). After 2015, annual average catches decreased from 171 t (2002-2014) to 47 t (2015-2019) (73% reduction), annual average number of boats operated (fishing efforts) decreased from 2.2 to 1.0 (46% reduction) and nominal CPUE show no decrease trends.

5. Incidental catch

In this section, incidental catch (VME species, seabird, mammals and turtles) are reported.

5.2 Incidental mortality (seabirds, mammals and turtles)

In the SEAFO database there are records of three seabirds (2 species) having been caught during Japanese longline daytime fishing in 2014. The seabirds caught were recorded by the ID codes “PUG” – Puffinus gravis (Great shearwater) & “DIM” – Thalassarche melanophris (Southern black-browed albatross).

5.4 Bycatch mitigation methods (Sea birds)

No offal dumping during hauling, deployment of bird scaring devices (Tori lines) and bottle test are mandated to mitigate seabird bycatch.

6. Current conservation measures and management advice

In 2015, the Commission adopted Harvest Control Rule (HCR) to decide TAC if no agreed stock assessments are available. This HCR had been applied in NAFO (Greenland halibut during 2011- 2017) and CCSBT (southern bluefin tuna), which uses average of slopes of CPUE in recent 5 years (Fig. 7).

Fig. 7 HCR for Patagonian toothfish adopted by the Commission in 2015

In the HCR, standardized CPUE is preferable to apply. Although SC estimated standardized CPUE using generalised linear models (GLM) five times in the past (2014, 2015, 2016-twice and 2018), all results indicated that correlation coefficients (goodness of fitness) were too low (r2 < 30%) to provide the plausible standardized CPUE for the HCR and SC did not agreed to use standardized CPUE for HCR.

Then SC12 (2016) agreed to apply nominal CPUE for the HCR. As nominal Japanese CPUE in the Meteor and Discovery seamounts areas are continuously available (2003-2018), SC12 (2016) agreed to use the slope of average of two nominal CPUE and applied in 2016.

Using the same method, TAC for 2019-2020 is computed as 275 t for Sub-Area D (Box 1) in SC (2018). Then SC (2018) recommends TAC for Sub-Area D of 275 t and a zero TAC for the remainder of the SEAFO CA for the years 2019 and 2020.

Box 1 Computation of TAC (2019-2020) using HCR

Slope (2014-2018) (Discovery) = -0.527 Slope (2014-2018) (Meteor) = +0.495 Slope (2014-2018) (based on average N_CPUE in 2 areas) = +0.0341

TAC (2019-20) = TAC (2017-2018) * (1+0.0341) =266(ton)*1.0341=275(ton) Difference (%) = (275-266)/266=0.034(3.4%) < 5% Hence TAC (2019-2020) = 275 tons
