Stock Name: Beaked redfish in ICES subareas 1 and 2 (Northeast Arctic)

 

Advice on fishing opportunities

The Joint Russian-Norwegian Working Group on Arctic Fisheries (JRN-AFWG) advises that when the MSY approach is applied, catches in 2025 should be no more than 67 191 tonnes, and catches in 2026 should be no more than 69 177 tonnes.

Stock development over time

Fishing pressure on the stock is below FMSY19+ and spawning-stock biomass is above Bpa and Blim.

***F=0 in 2025 and 2026

The advice for 2025 is 0.6% higher than the advice for 2023 due to increasing stock size and status quo advice, but 4.4% lower than the advice for 2024.

Basis of the advice

Advice basis Status quo F.
Management plan There is no agreed management plan for this stock. Long-term management plan options have been evaluated by ICES (ICES, 2018a).

Quality of the assessment

The stock was benchmarked in 2018. The choice of a scaling coefficient for the Norwegian–Russian ecosystem survey is a source of potential bias, but the advice is robust to this uncertainty.

Data from the pelagic survey in the Norwegian Sea (WGIDEEPS) was reviewed in the recent benchmark assessment and the survey is now included in the assessment model as age compositions. However, the survey series still does not appropriately cover the geographical distribution of the adult population.

Age determination is lacking for some surveys and catches in recent years. To account for the lack of catch-at-age data in some years a procedure using length distribution and a time-averaged age-length key was applied.

To smooth out spurious variations in SSB, caused by limited sample size in the weight-at-age of the 19+ group, a fixed weight-at-age function (i.e. common across years) was adopted for the assessment model during the Arctic Fisheries Working Group (AFWG) meeting in 2018 (ICES 2018b). In the 2024 assessment the maturity ogive was changed to fixed across time in a similar manner.

The SSB development over time is smoother than in previous assessments due to the change to a time-invariant maturity ogive. The upward revision of SSB in the 2024 assessment was driven by the addition of data from the 2022 WGIDEEPS survey, which is carried out every three years.

Issues relevant for the advice

Due to the suspension of Russian scientists from ICES, the assessment was conducted by a Joint Russian-Norwegian working group on Arctic Fisheries (JRN-AFWG) consisting of scientists from VNIRO (Russia) and IMR (Norway) (Howell et al., 202 4 ).

This advice has been conducted outside ICES and should not be considered as ICES advice. However, the assessment has been conducted following the previous procedures and based on the methodology agreed at the ICES benchmark in 2018 (ICES, 2018c).

There has been a significant change in the selectivity in the fisheries, with the fraction of the catch in the 19+ age class increasing in recent years (since 2017). Any evaluation of a FMSY or Fpa value is conditional on the Fbar and selectivities used in the evaluation. As a result of the changing selectivity, applying the same target Fbar will result in a reduction of the catch as a fraction of the fishable stock. Given that the catch is close to advice, and the SSB is relatively stable, we therefore propose F19+ status quo as an approximation to maintain the same overall fraction of the stock being caught. We note that this stock is due for a method revision in 2026 prior to the next release of advice, and the advice basis should be revised at that time.

Long-term management plan options have been proposed by Norway and Russia and evaluated by ICES (ICES, 2018a). In the absence of an agreed management plan, the MSY approach is used. The advice has been based on F19+ = 0.077. The highest fishing mortality of those tested during the MSE evaluations (ICES, 2018a) that was found to be precautionary is 0.06. The present advice is above F19+ = 0.06.

Bycatch of the endangered golden redfish ( Sebastes norvegicus ) should be kept at a minimum to allow for rebuilding of that stock.

Basis of the assessment

ICES stock data category 1
Assessment type Statistical catch-at-age model .
Input data Commercial catches: international landings (tonnes), age frequencies and weight-at-age from catch sampling of the pelagic and demersal fisheries and from the survey; survey indices: numbers-at-age from BS-NoRu-Q1-Btr, Eco-NoRu-Q3-Btr, Ru-Q4-Btr; proportion-at-age from deep pelagic ecosystem survey ; maturity data from BS-NoRu-Q1-Btr, Eco-NoRu-Q3-Btr, and commercial catch sampling; natural mortalities were fixed at 0.05.
Discards and bycatch Discarding and bycatch are assumed negligible.
Other information Last benchmark was in January 2018 (WKREDFISH; ICES, 2018c). Proposed management plans were evaluated in 2018 (WKREBMSE; ICES, 2018a). The JRN-AFWG 2024 changed maturity ogive from time-varying to time-invariant. A method revision is planned for 2026.
