Data quality issues
• Landings:
– Mis-reporting (area / species)
It was not possible to include Spanish commercial data for 2011.
– Insufficient or unrepresentative biological sampling
Catch coverage

ICES’ MSY
Same principles, concept and framework:
 Maximize average long-term yield (setting FMSY)
 Safeguard against low SSB (setting MSY Btrigger)

ICES’ MSY ... continued
Transition to MSY HCR by 2015
Moving from F2010 to FMSY-HCR in 2015 in 5 steps
FMSY-HCR transition 2013 = 0.4 F(2010) + 0.6 FMSY-HCR
FMSY-HCR transition 2014 = 0.2 F(2010) + 0.8 FMSY-HCR
FMSY-HCR transition 2015 = 0.0 F(2010) + 1.0 FMSY-HCR = FMSY-HCR
(values of advised F capped at Fpa for consistency with PA)
Data-limited stocks (DLS)
Activity in 2012 - Enormous scientific / advisory effort!
WKLIFE (February), RGLIFE (May); development by
Cefas, ACOM Leadership, ICES’ Secretariat and
ICES’ community
Three basic principles:
1) Available information should be used.
2) Advice for DLS should, to the extent possible, follow
the same principles as for data-rich stocks; i.e. aiming
towards exploitation consistent with MSY.
3) The less data available, the more precaution should
be taken when establishing limits for fishing
opportunities.
Data-limited stocks (DLS) ... continued
• Categorisation of stocks (6 categories) from data-rich
towards situations of decreasing information.
• Methods proposed for different categories – further
developments, simulation testing ... on-going
Common DLS situations:
• stock abundance index and F relative to FMSY-proxy
(plaice in VIId)
• stock abundance index available
(megrim VIIb-k & VIIIabd) (anglerfish …)
• F in relation to FMSY-proxy available (sole VIIh-k)
• time-series available of landings only
(sole VIIbc) (whiting IIIa)
Data-limited stocks (DLS) ... continued
Advice starts from recent catch (for most stocks, average
landings of last 3 years) and modifies it as follows:
• If stock abundance index available:
modify according to index trend in last 5 years
(Average last 2 years)/(Average 3 previous years)
• If current F relative to FMSY-proxy known:
modify according to change required in current F to
reach FMSY-proxy (could be in steps until 2015)
• If time series available of landings only:
no modification (but precautionary margin always
applied)
Data-limited stocks (DLS) ... continued
After appropriate DLS method has been applied, two
subsequent sequential steps:
1. Uncertainty window:
limit result to 20% change (increase or decrease)
(because results more noisy than with standard stock
assessments)
2. Precautionary margin: 20% reduction if stock status
relative to (candidate) reference points unknown,
unless there is evidence that stock is strongly
increasing or that exploitation (F or effort) has
decreased substantially
Data-limited stocks (DLS) ... continued
• Advice applicable to time-frame compatible with
measurable response in metrics used as basis for advice
• The less data available, the more precaution should be
taken when establishing limits for fishing opportunities,
and when precautionary margin applied:
no expected change in advice for a number of years
(e.g. 3 years tbd) unless important new knowledge
emerges

Mixed fisheries options presented in advice for first time: TAC for cod is the
limiting one in the North Sea
Mixed fisheries scenarios for North Sea stocks
In 2012, for the North Sea, ICES presents for the first time
in its advice:
an analysis of the implications of mixed fisheries under
current TAC and effort regimes
• Catch advice for each stock on a single stock basis
(based on MP, MSY framework or PA)
• Are the TACs corresponding to this advice in
agreement with each other in mixed fisheries context?
• Or are TACs for some species likely to be exhausted
much sooner than for others? (in which case, some
species will be caught above or below the TAC)
Mixed fisheries scenarios for North Sea stocks ...
continued
Analysis assumes:
• same fleet behaviour in 2012 and 2013 as in 2011
(same fishing pattern and catchability)
Five example mixed fisheries scenarios explored:
min: fleets stop fishing when their first quota exhausted
max: fleets stop fishing when their last quota exhausted
cod: fleets stop fishing when their cod quota exhausted
Status quo effort: effort (E) equal to most recent year
Effort management: E reduced according to regulations
min and max not realistic, but provide boundaries
Mixed fisheries scenarios for North Sea stocks ...

Mixed fisheries scenarios for North Sea stocks ...
continued
Fleets will change behaviour in response to their catch
possibilities for different species – but difficult to predict
Full value of mixed fisheries models will be realized with
input from managers and stakeholders on trade-offs
between different species in catch; e.g.
• scenarios that take into account value of different
species or other aspects influencing fleets’ behaviour
• scenarios that consider changes in fleets’ selectivities
• incorporation of mixed-fishery effects in LTMP
Multi-species considerations
Biological interactions occur between fish from a
population, across populations and with other
components of the marine ecosystem.
Some aspects incorporated in ICES’ single-stock advice
(e.g. natural mortality values that reflect history of
predator populations) – but more progress is required
Density-dependent effects imply that all the expected
increases in stock abundance based on an MSY
approach on an individual stock basis are unlikely to
occur simultaneously
Multi-species considerations ... continued
Response of the stocks to changes in fishing pressure
will also be affected by biological interactions
In most regions, reliable predictive models accounting for
the effect of biological interactions on stocks’ response do
not exist at present. If that continues to be the case, a
stock-by-stock MSY approach will be used based on the
observed response of the stocks once they have been
fished at FMSY
When reliable predictive models are developed:
multispecies fishing strategies to be developed to achieve
MSY on multispecies basis - requires evaluating tradeoffs based on managers’ and stakeholders’ preferences
Multi-species considerations ... continued
In the 2012 advice, ICES presents an illustration
concerning multi-species management for cod, herring
and sprat fisheries in the Baltic:
•
•
•
•
•
At this stage, work is illustrative
Meant as starting point for dialogue
Need to agree on objectives and risk tolerance
Will need a transition period
Focuses on most obvious interactions between cod,
sprat and herring. Not a full ecosystem or food-web
model
ICES will pursue further development of multi-species
work with a view to integrate it into advice when ready
Multi-species considerations ... continued
• For cod, sprat and herring in the Central
Baltic Sea it could be possible:
– to increase the sum of the sustainable yield of the
3 species combined in tonnes
– to improve the growth of individual fish of the 3
species
• However,
– cod yields will remain about the same
– the probability of low cod SSB will increase
• Results assume full spatial overlap
– Spatial overlap currently limited, cod in 25, sprat
and herring in 28-29 and 32
