Editorial overview

The project studies a policy mechanism rather than offering a management recommendation. Read the complete bilingual research note, When Sustainable Harvesting Becomes a Trap, for the model, Monte Carlo uncertainty, four reviewed figures, and the route from a perfect state variable to a monitorable policy.

Key findings

  • Fixed quota 8 produced 28 collapses in 150 runs, compared with 1 at quota 7.
  • No collapse was observed across the tested threshold-adaptive grid; the finite-sample upper risk bound remains non-zero.

Limitations

  • The model is not calibrated to a species or fishery.
  • Observation error, delayed control, age structure, and spatial dynamics are omitted.

Technical record

Detailed source, calculations, generated figures, and reproduction instructions are maintained in a private technical workspace. Public articles contain only manually reviewed interpretation and approved figures.
