Why is the southern bluefin tuna endangered

With low numbers of spawning adults, natural variation means there is a high risk of further declines. Several years of low juvenile survival, even with little or no change in fishing, can result in rapid decline.

There is no buffer of long-lived adults that exists when populations are higher. Management of Southern Bluefin is via international agreements on quotas, which can often lead to decision paralysis and status quo management. This management system can be slow to respond to problem signals such as low numbers, leaving the population ill-equipped to deal with the vagaries of juvenile survival.

In , the revelation of significant under-reporting of catches from the long-line vessels further increased the uncertainty in stock status and the risk of future tuna declines. An international body of major fishing nations, the CCSBT renewed its commitment to developing a formal rebuilding plan for the Southern Bluefin. Monitoring of the population has shown that the initial quota reductions have stopped the overfishing. Member scientists of CCSBT instigated a process of developing a robust rebuilding strategy in the early s.

These fish would eventually be sold to the food industry, making fishing in the wild less necessary, as these farms could supply the industry year round.

Technically, this catch should be included in the total amount of fish the whole of Australia is allowed to extract by CCSBT.

However, it remains to be seen how Australia will justify catching over its allocation. This app and online guide helps you make ethical and sustainable choices when it comes to seafood. If ever there was a fish that best represented all that is wrong with the way we fish, the Southern Bluefin Tuna would win the dubious award.
