Species has a combination of problems such as overfishing, high bycatch, and poor management.
Tuna, Yellowfin – Indonesia Longline These fish contain levels of mercury or PCBs that may pose a health risk to adults and children.

Yellowfin Tuna are found and caught in tropical and subtropical waters worldwide with a variety of fishing gears. This report evaluates Yellowfin Tuna caught in the Indonesia longline fishery in the Western Central Pacific Ocean.

Yellowfin Tuna in the Western Central Pacific are at a healthy abundance level and are currently being fished at the maximum sustainable level in the tropical equatorial region where the Indonesia fishery takes place. The longline fishery for Yellowfin Tuna also targets bigeye tuna and catches some swordfish, marlins, sharks, and sea turtles. Because several of these species are overfished, threatened, or endangered, the fishery is considered to have a high impact on other species.

Several management regulations have been established to manage these species at the regional level, through the Western and Central Pacific Fisheries Commission, but management in Indonesia is currently poor. Indonesia is working to improve management of their tuna fisheries. The surface longline gear used to catch Yellowfin Tuna causes no damage to bottom habitats, but since tuna fisheries catch several top predator species, there is some concern that these fisheries may affect ocean food webs and ecosystems.
