Background

• Funding from Fisheries Management Science
  Programme (FMSP)
• of the UK Department for International
  Development (DFID)
• New guides developed by FMSP Project R8468 to
  develop capacity for the use of existing FMSP
  stock assessment tools and management guidelines
  especially CEDA, LFDA, Yield and ParFish
• Developed as a collaboration between fisheries
  scientists (MRAG, Scales etc), educators (UK
  Field Studies Council, Indian Centre for
  Environmental Education), and with input from
  potential users in India and CRFM
• Guides build on discussions at 2005 CRFM Ad Hoc
  Methods Communications WG, re unpacking of
  management objectives
• Objective to develop a simple, clear process,
  promoting the adoption of a science-based
  framework for objectives-based management

What is a management plan?

• In simple terms, a document that
• Analyzes the current situation in a fishery
• Sets out some principles that should be followed
  in management
• Details goals and objectives for the fishery
• Says how they are to be achieved and
• Says how they are to be monitored.
• To monitor progress, objectives must be expressed
  in quantitative terms
• To achieve sustainable fisheries, the plan must
  have a base in stock assessment

13
Phase I. Preparing to write your management plan
Where are you now?

• Stage 1. Define the fishery. What is the
  fishery you are writing the management plan for?
• Stage 2. Stakeholder analysis. How are you
  going to involve the stakeholders?
• Stage 3. What is your fishery like now?
  Situation analysis.
• Stage 4. What is your management approach?

14
Stage 1. Define the fishery

• Decide on
• the species or type of fish
• the area of water or seabed
• the seasonality of fishing
• the method of fishing and class of boats and
• the people involved in the fishery.
• And the level of ecological complexity
• (a) Single species management
• (b) Multi species management
• (c) Ecosystem management

15
Stage 2. Stakeholder analysis

• Describe stakeholder numbers, and their
  importance and influence
• Decide approach for involving stakeholders in
  plan development (co-management). Effective
  participation is critically important.
• For guidance on stakeholder analyses, see
  Adaptive Learning Guidelines produced by FMSP
  Project R8292 (see www.adaptivelearning.info) and
  also in Tool 5 of the ParFish Guidelines.

16
Stage 3. Situation analysis What is your
fishery like now?

• Consider each dimension of the fishery
• Biological
• Ecological
• Social
• Economic
• Governance and others?
• For each dimension, describe
• the current situation and how it works
• how the situation is changing the trends over
  time
• Identify current problems and key management
  questions
• E.g. using Pressure-State-Response or SWOT
  frameworks

17
Stage 4. Management approach

• Two possible approaches to dealing with
  uncertainty
• The precautionary approach says lets be
  careful.
• Now required by UN Fish Stocks Agreement.
• The adaptive approach uses planned experiments to
  reduce uncertainty by learning from experience.
• Both approaches can be used together
• Management plan should be proactive more than
  reactive

18
Phase II. Developing the management plan Where
do you want to be?

• Stage 5. Overall purpose of your plan
• Stage 6. What are your goals?
• Stage 7. Developing your objectives
• Stage 8. Setting management standards
  indicators and reference points

19
Stage 5. Define the Purpose of the Plan

• A statement that summarises and combines all of
  the goals of the fishery into one single
  sentence.
• May be proactive, simply based on the stakeholder
  desires for the fishery, or also reactive if
  responding to some key perceived problems.
• Will usually emphasise sustainable development.

20
Stage 6. Setting the goals

• Define one or more goals for each dimension of
  the fishery biological, ecological, social,
  economic etc
• In an ideal world, we would like to maximise each
  of these goals (or minimise in some cases, such
  as bycatch)

21
Stage 7. Setting the Objectives

• Objectives are used to clarify the goals in
  quantitative terms, and to define the priorities
  between them
• Should be SMART and may follow the format
• a verb an indicator a relation and a
  reference point

To maintain the ribbon fish stock at all
times above 50 of its mean unexploited
level
22
Prioritising the objectives
Constraint added here
23
Stage 8. Setting Management Standards
Indicators and Reference Points

• Use indicators and reference points to help
  define the objectives
• Indicators show where you are at the moment, or
  where you might be in future
• Reference Points show where you would like to
  be.
• Indicators and RPs should be used in
  combination to express the objectives in ways
  that can be measured in quantitative fisheries
  assessments.

24
Indicators

• Key biological indicators fall into three
  categories
• The catch of fish (C)
• The size of the fish stock (the biomass, B)
• The amount of fishing (the pressure on the
  stock, F)
• In the short term, these are directly related to
  each other as .. C F x B

25
Long term (equilibrium) relationships between
Catch, Effort and Stock size Indicators(not
directly related!)
Catch
Catch
Stock size (biomass)
Fishing effort
Catch per unit effort (CPUE) or Stock size
(biomass)
Fishing effort
26
Reference points

• Give the point to aim at (target) or to avoid
  (limit) for each indicator and objective
• Can estimate using stock assessment tools (e.g.
  FMSY, F0.1) (or set as arbitrary, but agreed
  values, e.g. C450mt)
• Management advice is provided by comparing
  current values of indicators with the reference
  points, e.g.
• If Fnow gt FMSY Over-fishing
• If Fnow gt F0.1 Potential over-fishing
• If Fnow lt F2/3 MSY Assumed to be sustainable

27
Risk of alternative reference points
Maximum Catch at FMSY
Fcrash riskier Point at which species becomes
extinct
Size of
Catch
Amount of Fishing
28
Using reference points as targets or
limits(defining the objectives and control rules)

• Target RP - aim here, slightly above or below
  both OK

Indicator X
E.g. Catch rate E.g. spawning stock size
29
And precautionary reference points...
Limit RP
Precautionary RP
Take action at the Precautionary RP to avoid the
risk of getting to the Limit RP
Indicator X
30
Precautionary reference points

• Such points were adopted in response to the UN
  Fish Stocks Agreement (see point 5 of Annex II),
  to help make sure that the Limit RPs are avoided.
  
• The distance by which the precautionary point is
  removed from the LRP is usually set according to
• the uncertainty in the data
• and the risk tolerance of the manager (and/or
  other stakeholders)
• (see later)

31
Reference points andAnnex II of the UN Fish
Stocks Agreement

• Management strategies shall seek to maintain or
  restore populations of harvested stocks, and
  where necessary associated or dependent species,
  at levels consistent with previously agreed
  precautionary reference points. Such reference
  points shall be used to trigger pre-agreed
  conservation and management action. Management
  strategies shall include measures which can be
  implemented when precautionary reference points
  are approached.
• Fishery management strategies shall ensure that
  the risk of exceeding limit reference points is
  very low. If a stock falls below a limit
  reference point or is at risk of falling below
  such a reference point, conservation and
  management action should be initiated to
  facilitate stock recovery. Fishery management
  strategies shall ensure that target reference
  points are not exceeded on average.

32
Adding the Indicators and RPs to our example
33
Phase III. Developing the management plan How
are you going to get there?

• Stage 9. Action Management measures
• Stage 10. Decision control rules
• Stage 11. Finding the resources for your
  management plan

34
Stage 9. Management measures

• Input controls (fishing effort restrictions)
• Output controls (catch limits)
• Technical measures (size limits, closed seasons,
  closed areas etc)
• Input and output controls often vary between
  years, depending on the harvesting strategy and
  the state of the stock (as measured by the
  indicators)
• Technical measures control where, when and how
  fish are caught, and are usually fixed, or only
  updated every few years based on long-term
  assessments

35
Stage 10. Decision control rules

• Decision control rules define which measures or
  levels of controls will be used depending on the
  state of the fishery (as measured by the position
  of the indicators relative to the reference
  points).
• of immature Management measures
• fish in the catch
• --------------------------------------------------
  ----------------------------------------
• 20 or less Management measure is working
• Up to 30 Introduce a mesh size limit of X cm
• 30 - 40 Increase the mesh size limit to X5
  cm
• More than 40 Introduce a closed area or closed
  season to protect the nursery grounds or the
  seasons in which juvenile fish are caught

36
Decision control rules for setting level of
fishing effort a simple on-off example
FMSY
If Bnow lt BMSY, no fishing allowed next year
(danger zone)
Fishing mortality rate to be allowed next year
If Bnow gt BMSY, fishing allowed at rate of FMSY
next year
BMSY
Stock size this year
37
And a more precautionary sliding scale example
If Blim lt Bnow lt Bpa, fishing allowed next year
at a rate below Fpa, as set by the sliding scale
Flim
Fpa
If Bnow gt Bpa, fishing allowed at rate of Fpa
next year
If Bnow lt Blim, no fishing allowed next year
(danger zone)
Fishing mortality rate to be allowed next year
Blim
Bpa
Stock size this year
38
Allowing for uncertainty and risk in the RPs
Low risk Bpa at 90th percentile of Blim
distribution
Blim (BMSY)
Bpa (ileBMSY)
39
and for a higher risk threshold
Higher risk Bpa at 75th percentile of Blim
distribution
Blim (BMSY)
Bpa (ileBMSY)

Completing our example Management Plan summary
41
Stage 11. Finding the resources for the plan

• Budget Have you got enough money?
• Staff Have you got enough staff in the
  right places and with the right skills and
  qualifications?
• Facilities Have you got the right technical
  resources and equipment?
• Systems Have you got the right management
  structure and systems in place?
• Note you would need to have thought about this
  before now!

42
Phase IV. Planning to implement, evaluate and
review the management plan How will you know
you are there?

• Stage 12. Planning for implementation
• Stage 13. Planning to monitor your plan!
• Stage 14. Planning the review process

43
Stage 12. Implementation of the plan

• Publish the plan and consult with stakeholders
  (again)
• Develop detailed action plans with specific
  tasks
• Who should do each task
• When should it be done by
• Who should check it has been done, etc
• See e.g. in Table 12 of Managers Guide

44
Stage 13. Planning to monitor the plan!

• Monitoring the indicators provides feedback on
  the state of the fishery for management by
  decision control rules (see next slide)

Also monitoring other factors may help to explain
the results observed
45
Monitoring fishery indicators against limit and
precautionary reference points

• The precautionary plot used by ICES (North
  Atlantic)
• Note axes reversed
• X-axis fishing
• Y-axis stock size

46
Stage 14. Reviewing the plan

• Monitor the fishery and adjust input/output
  controls or other management measures as required
  say every 1-2 years
• Review and update the plan say every 3-5 years,
  or when circumstances or policy priorities change
