For any southern bluefin tuna fishing vessel that leaves a port, its captain shall daily report the length, weight, serial number of the tag of each southern bluefin tuna through the E-logbook system, and shall completely and accurately fill in the logbook designated by the competent authority, where there is any catch or not.
In the event that a southern bluefin tuna caught by the fishing vessel as referred to in the preceding paragraph is under any of the following circumstances, such catch shall be discarded immediately and the amount of discard shall be recorded in the logbook and the E-logbook system:
(1) The southern bluefin tuna is caught after the exhaustion of the southern bluefin tuna quota. In the case of a fishing vessel of both the seasonal targeting group and the bigeye tuna group in the Indian Ocean, such vessel shall also leave the fishing area.
(2) In the case of a fishing vessel of the seasonal targeting group, the southern bluefin tuna is caught after the vessel leaves the fishing area, regardless of exhausting the southern bluefin tuna quota of the current year or not.

During one fishing trip of any southern bluefin tuna fishing vessel, the discrepancy between the catch amount of the southern bluefin tuna recorded in the E-logbook and the actual landing amount shall not exceed 10% of the actual landing amount.
In case that the discrepancy exceeds the ratio as referred to in the preceding paragraph, whereas the following provisions are met, the competent authority, at its discretion, may deem that the discrepancy does not exceed 10%:
(1) For seasonal targeting group: the discrepancy is two metric tons or less.
(2) For bycatch group: the discrepancy is 300 kilograms or less.

Any of the following circumstance shall be defined as “seriously misreporting” as referred to subparagraph (12) of Article 13, paragraph 1 of the Act:
(1) For any fishing vessel of the seasonal targeting group, the discrepancy between the catch amount recorded in the E-logbook and the actual landing amount exceeds two metric tons as well as 20% of the actual landing amount.
(2) For any fishing vessel of the bycatch group, the discrepancy between the catch amount recorded in the E-logbook and the actual landing amount exceeds 300 kilograms as well as 30% of the actual landing amount.

Any southern bluefin tuna fishing vessel proceeds to operate in area south of 25°S shall employ at least two seabird mitigation measures, one of which shall be tori lines, the other shall be either the night setting with minimum deck lights or weighted branch lines. Specifications are as shown in Appendix 4.
The seabird mitigation measures taken during each fishing operation of fishing vessel shall be recorded in the E-logbook and logbook.
