The choice of procedure for deciding when to close fisheries regulated by CCAMLR: a simulation model
between catches being reported to Member countries, those catches being reported to the Secretariat ... , and any notification of a closure decision being transmitted from the Secretariat to fishermen via ... . The types of predictive method outlined in conservation measures to date rely upon fishing effort being ... in catches being 4.3% less than the TAC. This paper describes a simulation model constructed in order ... periods, and closes the fishery if these rates indicate that the TAC will be taken before the next report ... reporting periods are small (five days) and the reporting delay is minimal. It is recommended that in future ...
