Shipjacked tuna reducing the tuna population to half of 1970 levels and the finger points to…

Poached tunaThe next time you eat sushi, look carefully at the cuts of tuna you are about to eat. How do you know if the tuna hasn’t been poached or not? Out on the vastness of the Pacific Ocean, an estimated $520 to $740 million a year is being poached off the illegal catch of tuna and the finger is pointing at Japan being the largest consumers of raw tuna where it is immensely popular. Tuna fishing is carried out by registered fishing vessels, but when it comes time to report the number of tuna caught, the catches are apparently being under reported and the tuna are transferred to other ships to bring the poached tuna ashore for processing. As most would expect, Japan is not a member country of the Pacific Forum Fisheries Agency that does the monitoring. Who needs a pesky self-monitoring agency to report tuna catches to? Whale are already fair game for the Japanese so it shouldn’t come as no surprise tuna are next. Enjoy your sushi. (Note: this blogger doesn’t eat dead raw fish.)

Tuna poachers reap big profits

March 26, 2016

A new study has found that illegal tuna fishing in the Pacific Ocean is bringing in profits of $520 to $740 million a year.

The study, carried out by the Pacific Islands Forum Fisheries Agency, found that illegal fishing is typically carried out by licensed vessels that under-report their catches or transfer them to other ships at sea. That adds up to somewhere between 276,000 to 338,000 tons of illegally caught Pacific tuna every year.

The study did not name the specific nations where the poached fish end up, but Japan, which is the world’s largest consumer of tuna, clearly must be the market for much of it. Still, no one knows for sure because it is almost impossible to monitor. There are almost no international resources in place to check where fish come from, and even fewer resources to police the vast waters of the Pacific Ocean. Transferring tuna to other vessels or simply under-reporting what is caught is easily done.

If tuna populations were as viable now as nearly 50 years ago, illegal fishing might not be such a problem. However, many scientific studies have found that almost all populations of fish have halved since 1970. Overall, the Pacific supplies about 60 percent of the world’s tuna, but because of over-fishing its tuna populations are in danger of collapse.

The report found that one third of the illegally caught tuna was skipjack tuna (katsuo), followed by yellowfin tuna (kihada maguro) at 31 percent and bigeye tuna (mebachi maguro) at 19 percent. The International Union for the Conservation of Nature puts yellowfin’s status as near threatened, bigeye as vulnerable, or nearly endangered, while skipjack remains of less, though increasing, concern since stocks of the extremely popular Pacific Bluefin tuna (hon maguro) has been found to be depleted by up to 96 percent.

Sustainable, legal, regulated and enforced fishing of tuna in the Pacific is in everyone’s interests, especially countries like Japan where tuna is immensely popular. Such illegal fishing is a form of robbery and often fails to distinguish between juvenile and mature tuna, so that tuna populations are being depleted faster than they can be replaced. Distinguishing the catch is important because tuna is a fish that takes many years to reach maturity and begin to reproduce. Bluefin tuna can live 40 years and reproduce many times, if given the chance.

Japan should help to set up a system of monitoring, both financially and technologically, and push for international agreements on how to enforce the legal size of catches. Management of juvenile stocks of tuna has met with some success, but deserves greater support.

Conservation and sustainable fishing of tuna should become the norm, but the way must be led by one of the largest consumers of tuna in the world—Japan.
