In case that the quota has been granted, the competent authority shall retrieve the quota of the current year in accordance with the percentage that the number of month(s) for fisheries cooperation accounts for the whole year. In case that the quota of the current year is unable to be retrieved, the competent authority shall deduct the allowed annual of such vessel in the following year.

The targeting of bigeye tuna as referred to in the preceding paragraph means that the bigeye tuna catch amount of the fishing vessel during six months exceeds 50% and above of its total catch amount of the same period.
Any small scale longliner fishing in the area north of the equator shall not target albacore tuna.
