Logbook data submission is mandatory for all large purse-seine vessels under IATTC regulations and since the 2005 implementation of the HMS fisheries management plan, for small coastal purse-seine vessels targeting HMS. The data are used to monitor the fishery and contribute to stock assessments.

Logbooks are collected by the IATTC, SWFSC, WCRO or PIRO and are managed by IATTC staff.
