					  MANAGEMENT AND
 CONSERVATION OF AN
OVER-EXPLOITED FISHERY
      RESOURCE
    THE CCSBT EXPERIENCE




                           1
CCSBT Position - 2007
   the fishery is badly depleted

   spawning stock biomass is most likely at around 10% of its pristine level and in a very
    vulnerable situation

   its management measures have not been effective in controlling the catch

   there is very little reliable data on which to make stock assessments to support
    management decisions

   a sum, by my estimate, exceeding $5 million has been spent on developing a management
    procedure, which is now moribund because of data problems

   its management plan to restore the spawning stock biomass to the 1980 level by 2020 is
    unattainable

   management solutions to these problems will be expensive and difficult for the CCSBT and
    its history would not give confidence that its structure and membership will be up to the
    task




                                                                                              2

                                       4
CCSBT Position - 2001
   a competent legal structure

   almost 90% of the reported catch was from members or cooperating non-members with the
    remaining 10% of the catch being competently monitored

   a single fish species

   a small number participants operating industrial fleets with well developed domestic
    fisheries management arrangements

   strong and independent scientific support available

   a central database managed by the CCSBT Secretariat

   catch being reported to CCSBT settings

   an effective trade document system/vessel register to regulate trade

   Agreement to a management procedure to set TAC

   a monopsonist buyer of SBT (Japan), which was a member, effectively militating against
    erosion of the effectiveness of CCSBT measures



                                                                                             5

RFMOs – Inherent Structural Problems
   member behaviour in placing national interests before good international
    governance

   consensus decision making, which leads to lowest common denominator
    outcomes

   the disconnect between the need for day-to-day management of a fishery and
    the use of a vehicle structured on diplomatic negotiation principles, which
    meets once a year

   unwillingness to meet the resource costs of managing the fishery
    internationally

   the propensity for decision making to always lag well behind the
    circumstances in the fishery until crisis emerges
