definitions and measurement
Definitions and measurement
  • OVERCAPACITY is, for a given resource condition, the situation where the amount of fish that can be caught over a period of time by the fully utilised (unconstrained) fleet is greater than required to ensure a target level of sustainable exploitation.
  • Ct = q.E.Bt
  • Bt+1 = p(Bt) + Rt - Ct
    • using CPUE, E, B characterise q for fleets
    • Estimate maximum possible Cmax
    • Cmax should be <= YMAX
causes of overcapacity
Causes of overcapacity
  • Non-maleable capital
  • Open access creates individual incentives
  • Government intervention (subsidies) – in and out
  • Overseas subsidies – export of capital in access agreements
  • Technology developments – effort creep
  • Management systems
    • That encourage capital stuffing/race to fish
    • With intrinsic boom/bust cycle mismatches
  • Unstable management reference points – MSY
example north sea cod
Example – North sea cod

Subsidised building

unstable management systems

Arctic cod

Unstable management systems
  • Management by output control (TAC) assumes full knowledge and compliance
  • Output management does not usually track capacity (or q)
  • YMAX should be limit not target reference point
consequences
Consequences
  • Economic waste
  • Resource overexploitation
  • Capital transfer – exporting the problem
  • IUU
  • Discarding, highgrading, blackfish
  • Overcapacity problems often negate all other management attempts, eg ecosystem based management
management of capacity
Management of capacity
  • IPOA
    • Efficient transparent and equitable management of capacity by 2003 (!) or 2005
incentive blocking
Incentive blocking
  • Limited entry
  • Non-domestic capacity
  • Buy back
  • Gear and vessel restrictions, catch limits
  • TACs
  • Easy to implement, particularly suited to mixed developing country fisheries
  • Combinations of limited entry & TAC work but require monitoring
  • Encourage competition and race to fish – likely to end up here again!
incentive adjusting
Incentive adjusting
  • ITQs
  • ITEQ individually transferable effort quotas
  • Taxes & royalties
  • Territorial user rights to fish (TURF)
  • Saving (rather than recapitalising) supra-normal profits
  • Inspire responsibility/ stewardship
  • Remove incentives to overcapitalise
  • Complex to implement
conclusions
Conclusions
  • Monitor and continually adjust capacity
  • Move away from YMAX brinkmanship
  • Change management approaches to deal with boom-bust
  • Subsidies ….
