The Tuna Commission is unlikely to back calls by Greenpeace for a 50 percent reduction in the levels of tuna catch by fishing fleets in the region.
Greenpeace says it is concerned that bigeye and yellowfin tuna are being overfished with current catch levels of all tuna at over 2 million tonnes.
The executive director of the Western and Central Pacific Ocean Fisheries Commission, Andrew Wright, says the problem is that bigeye and yellowfin are caught with skipjack tuna which is being fished at sustainable levels.
He says skipjack represents a vital resource for Pacific Island countries, so the challenge is to come up with measures that ensure the other two species are protected.
"It's unlikely that the Commission will support a 50 percent reduction in catch levels. But, the commission is looking at means to try and reduce the incidence of yellowfin and bigeye catch. The scientific committee recommended that it was required to reduce the catch of bigeye tuna by 25 percent."
Mr Wright says its also been recommended that the take on yellowfin be reduced by 10 percent.
He says the Commission is working on a series of measures, including vessel monitoring, observer programmes and the means to inspect vessels.
