AGREED RECORD OF CONCLUSIONS OF FISHERIES
CONSULTATIONS BETWEEN THE EUROPEAN UNION AND
NORWAY ON THE REGULATION OF FISHERIES IN SKAGERRAK
AND KATTEGAT FOR 2013
The Delegations noted that catches of herring in ICES Division IlIa
consist of herring from several stocks and that the absence of a method
for establishing a TAC for herring in this area is not satisfactory. The
Delegations therefore agreed to establish a Working Group on
management measures for herring in ICES Division IlIa (Skagerrak).
This Working Group, the Terms of Reference for which are set out in
Annex V, shall develop and recommend alternative methods to set a
TAC for herring in this area that is consistent with maximum sustainable
yield.
Working Group I meeting, 19 February 2013, Amsterdam, The Netherlands
WBBS herring (IIIa and 22-24)
Preliminary conclusions/recommendations from the
benchmark
• New assessment model SAM
Stock dynamics perception remains unchanged with
comparable estimates of SSB and F especially since the mid
2000s
• Constant split of catch options (50:50) between IIIa and 22-24
should be continued
• Optional transfer of quota In case an optional transfer of quota between IIIa and the North Sea is agreed by
managers, the Pelagic RAC will provide HAWG with an estimate of the proportion of
the TAC for IIIa that will be fished in the North Sea in the assessment year. This
estimate will be put forward at least 2 weeks (?) before the working group meeting.
If this proportion is not available an average of the last 3 (?) years will be used to
estimate the proportion of the TAC not taken in the area.
North Sea herring
Revision of the LTMP, until then catches of no
more than 480 200 t (465 750 t for A-fleet).
STECF agrees with ICES.
With regards to the discard ban to be introduced in the Skagerrak STECF
notes that discards estimates are not available for the fisheries in the
Skagerrak and STECF is not in the position to advice if the discard ban is likely
to affect the herring fisheries.
Based on WKHELP: Current HCR with 50/50
stabilizing mechanism, Btrigger will be set to 1,3 Mio tons
and F to 0.24, banking or banking & borrowing of 10%
or any lower sustainable number will be applied.
478 000 tonnes (405 000 in 2012)

North Sea herring: new EU-Norway request
Working Group I meeting, 19 February 2013, Amsterdam, The Netherlands
ICES is requested to evaluate the following alternatives reflecting fishing mortality for 2 ringers and older in
the range between F 0.26-0.30 in steps of 0.01.
Alternative 1
1) Blim = 800 000 tonnes, Btrigger = 1,3 Mio tonnes
2) If SSB > Btrigger, then F = (0.26-0.3) for 2 ringers and older and 0.04 for 0-1 ringers
3) If SSB < Btrigger but > Blim, then:
• F-((F-0,1)*(1,300,000-SSB)/500,000) for 2 ringers and older,
• and no more than 0.04 for 0 - 1 ringers
4) If SSB < Blim, then F = less than 0.1 for 2 ringers and older and F = less than 0.04 for 0-1
ringers
5) If rules in 3 and 4 would lead to a TAC which deviates by more than 15% from the previous
TAC, the TAC shall be fixed to no more than 15% greater or 15% less than the TAC of the
preceding year.
6) If rule in 5 would lead to reference F which deviates by more than 15% from reference F
resulting from 3 and 4, reference F shall be fixed that is no more than 15% greater or 15% less
than reference F resulting from 3 and 4.
North Sea herring: new EU-Norway request
Working Group I meeting, 19 February 2013, Amsterdam, The Netherlands
Alternative 2
1) Blim = 800 000 tonnes, Btrigger = 1,5 Mio tonnes
2) If SSB > Btrigger, then F = (0.26-0.3) for 2 ringers and older and 0.05 for 0-1 ringers
3) If SSB < Btrigger but > Blim, then:
• F-((F-0,1)*(1,500,000-SSB)/700,000) for 2 ringers and older,
• and no more than 0.05 for 0 - 1 ringers
4) If SSB < Blim, then F = less than 0.1 for 2 ringers and older and F = less than 0.04 for 0-1
ringers
5) The TAC shall be set as the arithmetic mean of the quotas resulting from the application of the rules
set out in 2 and 3 and the TAC of the preceding year.
Both alternatives shall be evaluated with and without inter annual quota flexibility of
+/- 10% when the SSB is above Btrigger
Herring West of Scotland (VIa North)
27 480 tonnes
In agreement with the ICES advice
27 480 tonnes
27 480 tonnes (22 900 in 2012)
Herring in VIaSouth and VIIbc
No catches unless rebuilding plan is
implemented
No catches unless rebuilding is implemented Proposed rebuilding plan from the Pelagic RAC could not be considered
precautionary because it lacked provisions for closing the fishery if the stock
fell very low. In addition, the assessment results from ICES are too unreliable
to be used as a basis for a catch forecast. As a result STECF is unable to
provide the forecast catches corresponding to a value for F of F=0.2 prescribed
in the proposed management plan
Not referring to PRAC’s revised rebuilding plan
• Proposed revised rebuilding plan evaluated by
ICES/STECF
• TAC 2013 calculated by ICES/STECF based on rebuilding
plan
1 500 tonnes, based on clause 3 in proposed
revised rebuilding plan (4 247 tonnes in 2012)
Working Group I meeting, 19 February 2013, Amsterdam, The Netherlands
Herring in VIaSouth and VIIbc
Working Group I meeting, 19 February 2013, Amsterdam, The Netherlands
STECF 41st Plenary meeting report, 5-9 November 2012, referring to
revised rebuilding plan:
• STECF would like to thank the PRAC for recognizing the issues raised and
appreciates the efforts made to improve the plan. Although there remain some issues
of clarity which are noted below overall STECF considers that this plan is a good
attempt at drafting a management plan for this stock and is grateful to the PRAC for
following this initiative.
• In the current situation the plan has at least two interpretations. The PRAC should be
encouraged to work with an individual who is to carry out the evaluation to ensure
that each clause has its intended changes described as an algorithm so it can be
tested and then PRAC should arrange for a full evaluation to be carried out during
2013.
Celtic Sea herring (VIIghjk and VIIaS)
19 000 tonnes (MSY framework)
In agreement with the ICES advice
• 17 200 tonnes (proposed LTMP)
• 19 000 tonnes (MSY) if ICES rejects LTMP
17 200 tonnes (21 100 tonnes in 2012)
Working Group I meeting, 13 September 2011, Leiden, The Netherlands
Celtic Sea herring (VIIghjk and VIIaS)
Outcome ICES evaluation of proposed LTMP:
ICES advises that the proposed LTMP for Celtic Sea herring is in
accordance with the precautionary approach and leads to sustainable
yield. The plan provides stability in catches over time, at the expense of
maximizing yield.
Irish Sea herring (VIIaNorth)
5 100 tonnes (MSY)
In agreement with the ICES advice, but: STECF advises that if the agreed TAC for herring in VIIa for 2012 (4,752 t) is
increased to 5,280 t, and if caught but not exceeded, F in 2012 is predicted to
be F=0.23 which is below FMSY. Fishing at FMSY (F=0.26) in 2013 is
predicted to give rise to landings in 2013 of 4,993 t. Under the above
assumptions SSB in 2013 and 2014 is predicted to remain well above
established spawning stock biomass reference points.
• TAC in 2012 is increased to 5 280 tonnes
• TAC in 2013 is set to 4 993 tonnes (MSY)
4 993 tonnes (4 752 tonnes in 2012)
Irish Sea herring (VIIaNorth)
• Workshop under the auspices of GAP2 in July 2012 on
developing LTMP
• Minutes have been distributed previously
• Points to be explored for a LTMP: • Harvest rates and trigger points (MSYBtrigger, Fmsy)
• 15% TAC constraint
• Fixing TAC for 2-3 years at current level
• Leave out 1970’s data in simulation due to high uncertainty
• Assess effects of reducing Douglas Bank closure
• No further progress so far due to time and other
resource constraints of scientists

North East Atlantic herring
619 000 tonnes (LTM plan)
In agreement with ICES advice
• 619 000 tonnes
• International inspection team to ensure true and
reliable recordings of landings
619 000 tonnes (833 000 tonnes in 2012)
North East Atlantic mackerel
Between 497 000 and 542 000 tonnes
(LTMP)
In agreement with the ICES advice
• Urged the Commission to come to an acceptable
agreement with the Coastal States
• International inspection team to ensure true recording of
landings
• Improve data collection to overcome stock assessment
uncertainties
