Logbook

Official record of catch and effort data made onboard by fishers during the fishing operations, which includes information on both target species and non‑target species. T‑RFMOs and flag states usually require that vessels complete logbooks, since they are an essential tool of data collection for stock assessment and further development of management measures. They can be traditional paper logbooks or electronic logbooks (e.g. e‑Tunalog).
