Association president Sylvester Pokajam, who's the former managing director of the National Fisheries Authority, said shifting climatic conditions in the western Pacific were pushing certain fish species away from PNG, The National newspaper reports.
The sector was struggling for revenue as a result, Pokajam said, adding that on the bright side, more fishing vessels were flying the PNG flag.
Pokajam also praised fishing companies who had established canneries in PNG, providing employment for local people. PNG-based operations were processing nearly half of the fish caught in the country's waters, a large portion of which was tuna, he said.
The association recently applied to have its purse seine skipjack and yellowfin tuna fishery assessed for certification by the Marine Stewardship Council. The fishery includes onshore processing plants supported by PNG-flagged vessels and locally based foreign fishing vessels, The National reported.
