Nauru is expecting to have to ban purse seine fishing from its waters again for the remainder of the year.
The Nauru Fisheries and Marine Resources Authority's chief executive says Nauru has almost used up its allocated fishing days for this year, as it did last year.
Charlestone Deiye says it's estimated the country will have run out of fishing days by next month.
Nauru is one of eight countries that are parties to the Nauru Agreement, which involves a commitment to limiting fishing days to sustainably manage Pacific tuna stocks.
Nauru's closure of its exclusive economic zone to purse seiners won't affect its small-scale and subsistence fishing boats, and doesn't apply to fishing within the Nauru Territorial Sea, which is reserved for locals.
The Solomon Islands closed its waters to purse seiners in May.
