> From a fisheries industry perspective, fishermen are forced to get rid of hybrids, because you're not allowed to sell these fish to consumers. I believe they're seeing big losses. From the biodiversity impurely scientific stand point, if these two species continue to mix, and leads to just one large group of hybrids, that means a loss of bad diversit, so that is problematic.
If they aren't removed in the right way the toxins can kill a person, in just 20 minutes. Death by fugu is extremely rare. That taste of danger though means the fish can sell for more than $200 per kilogram at markets like this.>>
But lately, warming waters have changed the fugu as Reuters' Mari Saito explains.>> There's been an increase in hybrid pufferfish in waters around Japan. This is because warming waters is changing the natural habitat of this fish. Where they use to normally swim around sea of Japan, they're moving more north, some of them are shifting to the Pacific Ocean side of the country and intermixing with other sub species of the same fish.
>> The hybrids are sometimes very hard to tell apart from their pure breed cousins.>> The government here bans the sale and distribution of hybrids, because the poison, the poisonous parts of the fish can come from different parts.>> While the freaky fugu used to be red, experts say hybrid fish are now much more common.
They're going from one in a 1,000 to more than 20% of some catches today.>>
>> Japan's Health Ministry says it's still collecting information about the hybrids. But so far there's no official word on exactly what to do about the changing nature of one of Japan's culinary traditions in the face of a changing climate.
