Af hensyn til effektiviteten og accepten af kontrolsystemet er det vigtigt, at organisationerne inddrages, at der i tilfælde af mistanke er adgang til de enkelte staters data, at der er effektive forbindelser mellem medlemsstaternes kontrolorganer, og at der frem for alt er ligebehandling.
Factors which are important in ensuring the effectiveness and acceptance of the monitoring system include: involvement of fishermen's associations, access to national data in suspicious cases, effective networking of monitoring agencies in the various Member States, and, in particular, equal treatment.
