Prior state
Quota systems remained largely based on historical catch shares and single-species targets that no longer matched biological reality.
Material change
Regional management organizations revised allocation formulas and moved toward multi-species, ecosystem-based, and climate-adjusted quotas, including new mechanisms for stock-sharing among historical and newly accessible jurisdictions.
Why now
The cumulative displacement of major commercial stocks relative to historical fishing grounds produced both scientific clarity and political crises among fishing communities and states.
Mechanism and resistance
Resistance came from historical rights holders and from states losing access. Counter-pressure arose from scientific advisory bodies and from states gaining new access.
Consequences
Some historical fishing communities contracted; new regional participants expanded; overall biomass recovery improved modestly in better-managed systems.
End state
Climate-adjusted, ecosystem-based quota regimes operated in the majority of major regional fisheries management organizations.
Observable test
Official regional fisheries management decisions document climate-adjusted or ecosystem-based allocation formulas in force for the majority of key commercial stocks under their jurisdiction.
Disconfirming sign
Continued reliance on historical catch-share formulas despite documented stock redistribution.
