1.   the fishery for tunas by purse-seine vessels in the EPO shall be closed from either (1) 1 August to 11 September; or (2) 20 November to 31 December.

2.   each IATTC Party, cooperating non-party, fishing entity or regional economic integration organization (“CPC”) shall prohibit fishing by all of its purse-seine vessels during one of the two periods.

3.   landings, transshipments and commercial transactions in tuna or tuna products originating from fishing activities that contravene this resolution are prohibited. 

For 2004, the following closures are in effect:

Weekly reports are sent to the governments, informing them of possible illegal fishing activity during the closure.
