During the s, it was revealed that the former Soviet Union had falsified its whaling data over the previous 30 years, in particular with respect to the size and number of sperm whales being hunted. Ignoring regulations set by the International Whaling Commission IWC , the Soviets regularly killed sperm whales that were below the minimum length, and misreported female whales as larger males in order to make their number tally with the amount of oil being produced from the hunts. Only when the Soviet Union collapsed did the truth come out, revealing that around , whales have been illegally killed. Now scientists have taken a look at figures submitted by Japanese whalers who were operating in the same areas as the Soviets and discovered that there is a large discrepancy between the two. By contrast, the Soviet fleets operating during this period killed 12, females, of which only 6.

  • The Japanese have been living with whales since ancient times.

Like fishermen, whale hunters sometimes alter the details of their catch. In the s, Soviet Union USSR whalers illegally killed almost , cetaceans, but reported taking far lower numbers. Now, it seems that Japanese whalers in the North Pacific also manipulated their numbers around this time, according to a new study. Both countries—along with all other whaling nations—began submitting catch statistics, including the sex and length of killed whales, to the International Whaling Commission IWC in The organization, which oversees the global conservation and management of whales, specified where each country could hunt and the number and species of whales that they could take.

Member nations also agreed to carry biologists on board whaling vessels to collect the catch data. But in the USSR went rogue and began hunting whales illegally. Over the next 30 years, its whaling industry killed an estimated , more cetaceans than it reported to IWC.

Fortunately, four Soviet biologists kept secret, correct records, which were declassified in the s. Because this species had been heavily hunted for its oil since the late s, IWC ruled that only sperm whales longer than Male sperm whales may reach 20 meters in length, and females attain a maximum size of only 14 meters.

But the USSR whalers brushed aside this regulation, falsifying female lengths or recording females as larger males. While interviewing the Russian scientists, Ivashchenko got a tip. So, come on! These numbers are just not real. Over those 2 years, the Japanese whaling fleets in the North Pacific reported harpooning females.

Of these, —or In contrast, the real Soviet data show that their whalers who were hunting in the same area as the Japanese killed 12, females—yet only or 6. The doctored Japanese records report that their fleet even managed to catch females in that were After , when IWC required whalers to have independent observers on board, the Japanese reported catching far fewer large female sperm whales or those of the minimum size , Ivashchenko and Clapham report today in Royal Society Open Science.

Discovering that the Japanese whaling data for sperm whales is likely fabricated opens a can of worms, says John Frizell, a spokesman with Greenpeace in the United Kingdom. How many studies are now invalid because of this?

So far, no one in Japan has stepped forward to help correct the data as the Russian biologists did. Frizell notes that the Japanese delegation gave similar responses at the recent IWC meeting in San Diego, California, where Ivashchenko presented an earlier version of the paper. Scott Baker, a conservation geneticist at Oregon State University, discovered in that the Japanese regularly underreport the number of whales killed as bycatch.

Japan falsified whale hunting data in s, according to study | Science | AAAS

During the s, it was revealed that the former Soviet Union had falsified its whaling data over the previous 30 years, in particular with respect to the size and number of sperm whales being hunted. Ignoring regulations set by the International Whaling Commission IWC , the Soviets regularly killed sperm whales that were below the minimum length, and misreported female whales as larger males in order to make their number tally with the amount of oil being produced from the hunts.

Only when the Soviet Union collapsed did the truth come out, revealing that around , whales have been illegally killed. Now scientists have taken a look at figures submitted by Japanese whalers who were operating in the same areas as the Soviets and discovered that there is a large discrepancy between the two.

By contrast, the Soviet fleets operating during this period killed 12, females, of which only 6. Once adjustments were made for the effort involved, the Japanese figures show they were somehow 9 times more successful at catching whales above the minimum length than their Soviet rivals, and there were considerable differences in the size of whales being taken by the two countries.

Further doubt on the validity of the Japanese figures is cast by the fact that once observers began being placed on whaling vessels in , the number of whales Japan killed that met the minimum length dropped significantly. These findings, along with those on the Soviet illegal catches, clearly emphasize that a proper monitoring and reporting of catch data is close to impossible as there will always be room and loopholes that people can use to cheat and so falsify reports.

As the report notes, this falsified data forms part of the IWC catch database; researchers use it. How many studies are now invalid because of this? If the Japanese whalers falsified their sperm whale catch data, then it is very possible that they submitted inaccurate reports on humpback and fin whale hunts too.
