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

11What 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

13Phase 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?
14Stage 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
15Stage 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.
16Stage 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
17Stage 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
18Phase 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
19Stage 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.
20Stage 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)
Goals Objec-tives Management standards Management standards Management measures Management measures
Goals Objec-tives Indicators Reference points Management measures Decision control rules
Biological To maintain the ribbon fish stock at or above the levels necessary to ensure its continued productivity
Economic To maximise the net incomes of the participating fishers
Social To maximize employment opportunities for those dependent on the fishery for their livelihoods
21Stage 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
22Prioritising the objectives
Goals Objectives Management standards Management standards Management measures Management measures
Goals Objectives Indic-ators Reference points Management measures Decision control rules
Biological To maintain the ribbon fish stock at or above the levels necessary to ensure its continued productivity To maintain the ribbon fish stock at all times above 50 of its mean unexploited level
Economic To maximise the net incomes of the participating fishers To maintain net income per fisher at a level above the national minimum desired income
Social To maximize employment opportunities for those dependent on the fishery for their livelihoods To include as many of the existing participants in the fishery as is possible given the biological and economic objectives above
Constraint added here
23Stage 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.
24Indicators
- 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
25Long 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
26Reference 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
27Risk of alternative reference points
Maximum Catch at FMSY
Fcrash riskier Point at which species becomes
extinct
Size of
Catch
Amount of Fishing
28Using 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
29And 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
30Precautionary 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)
31Reference 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.
32Adding the Indicators and RPs to our example
Goals Objectives Management standards Management standards Management measures Management measures
Goals Objectives Indicators Reference points Management measures Decision control rules
Biological To maintain the ribbon fish stock at or above the levels necessary to ensure its continued productivity To maintain the ribbon fish stock at all times above 50 of its mean unexploited level Current stock size, Bnow, as estimated by the Schaefer production model using X data and Y fitting method 50 of the carrying capacity, K, as estimated by the Schaefer production model (i.e. above BMSY) using X data and Y fitting method
Economic To maximise the net incomes of the participating fishers To maintain net income per fisher at a level above the national minimum desired income Net income per fisher measured using A data and economic model B The national minimum desired income (e.g. US10/day)
Social To maximize employment opportunities for those dependent on the fishery for their livelihoods To include as many of the existing participants in the fishery as is possible given the biological and economic objectives above Number of fishers employed in the priority fishing fleets Number of fishers that would maintain biomass above BMSY (i.e. fMSY) and allow at least the minimum desired income per fisher
33Phase 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
34Stage 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
35Stage 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
36Decision 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
37And 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
38Allowing 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)

Biological To maintain the ribbon fish stock at or above the levels necessary to ensure its continued productivity To maintain the ribbon fish stock at all times above 50 of its mean unexploited level Current stock size, Bnow, as estimated by the Schaefer production model using X data and Y fitting method 50 of the carrying capacity, K, as estimated by the Schaefer production model (i.e. above BMSY) using X data and Y fitting method Catch controls and/or effort controls, set at levels estimated by the production model that would maintain biomass above BMSY. In combination with technical measures, e.g. gear controls, allowing only low powered fishing vessels thereby employing large numbers of fishers. If current stock size, Bnow is less than BMSY, then set next years catch or effort to zero. If Bnow is greater than BMSY, then set next years catch or effort to the level that should achieve the long term MSY. (See also alternative sliding scale options below)

41Stage 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!
42Phase 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
43Stage 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
44Stage 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
45Monitoring 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
46Stage 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
