Handy updates on Asia-Pacific tuna stock status

 

Fisheries and aquaculture are confronted with continuing problems such as climate change, growing human populations, low income of small scale fishers and fish farmers, and competitive production and trading conditions. People should be confronting and discussing the challenges in order to come up with solutions on how we can respond; and the community should be resilient and adaptive in combatting the challenges. We cannot immediately solve some problems, such as overfishing, illegal fishing, depletion of marine resources, as they have deep root causes, but we are learning how to address them. Governments do their best to manage fishery resources to meet these challenges. Decision makers and the public also need to continually listen to new information so that they are equipped with knowledge for sustaining marine and aquaculture resources and protecting people who depend on them for nutrition, livelihood and business. Research is an important information gathering tool that contributes to policy and decision-making. The Asian Fisheries Society and its partners are taking a lead in making new information accessible through its platform AsiaPacific-FishWatch providing essential information on fish harvested or farmed for food in Asia-Pacific. I am pleased that AsiaPacific-FishWatch gives attention in its profiles and posts to the critical social, economic and market character of the value chains. The Asian Fisheries Society emphasises equally social and economic knowledge and biological, physical and technical knowledge.

Handy updates on Asia-Pacific tuna stock status

Written by Meryl J Williams

The biennial INFOFISH World Tuna Trade Conference and Exhibition in Bangkok (21-23 May 2014) is a good time to check the most up-to-date information on the status of tuna stocks, including those of the Western and Central Pacific and Indian oceans.

Tuna Trade 2012The International Seafood Sustainability Foundation makes this check easier for us. It commissions its Scientific Advisory Committee to overview analyses of the status of status of stocksin all regional fisheries management bodies, and other experts to check stocks against the Marine Stewardship Council (MSC) standards.

Status of Stocks

For the Western and Central Pacific Ocean (WCPO), skipjack, yellowfin, bigeye and albacore tuna, the status of the stocks are unchanged since the last major update in 2012. Although none of the stocks are currently overfished, concern is expressed for bycatch in certain types of fishing (longline and certain sections of the purse seine fisheries) and the lack of management controls in the equatorial area of the yellowfin fishery and in the bigeye fishery.

In the Indian Ocean, skipack and bigeye status did not change since the last assessments; the yellowfin stock needs reassessment because of recent higher fishing levels; and for albacore the abundance has changed from yellow to green despite that fishing mortality went from yellow to orange. For all stocks, bycatch in purse seine, longline and the large and growing gillnet fisheries is of concern.

Assessment against MSC Standards

The assessments against MSC standards (by experienced assessors) covered the sustainable fish stocks principle (P1) and the effective management principle (P3), but did not do the minimising environmental impact principle (P2). Of the 8 Western and Central Pacific and Indian Ocean stocks assessed, 3 received a passing score on P1, namely WCPO skipjack and Indian Ocean skipjack and yellowfin. Among the regional management organisations, the Western and Central Pacific Fisheries Commission was the most highly rated globally, just ahead of Inter-American Tropical Tuna Commission.
