In Japan, where fishing is a popular pastime, fish meat is used to make a cheap, convenient meal.
But this popular dish is actually a source of pollution in a country that has strict rules on what can be eaten.
The World Health Organization has found that in Japan, plastic bags are being used to kill fish in the largest amount in the world, and the practice is increasing at a rapid pace.
The WHO estimates that more than 40 percent of the fish caught in Japan each year are sold as sushi, or as the Japanese name for fish, miso.
Fishermen say they are being killed for their meat by fishermen in the area of Otsu, which is just south of Fukushima, who have been killing fish in large nets in the river.
A local fisherman told CNN affiliate NHK that fish in his catch were being poisoned.
According to Japan’s Environment Ministry, the number of fish killed for miso in the Fukushima area has risen dramatically, from around 2,000 in 2010 to around 3,000 today.
And that number is growing even faster than the number killed for fish.
But what is miso?
It’s a fermented soybean-based food that’s typically eaten as a dip, or a snack.
There are many varieties of miso, but the Japanese call it miso koji, or miso jelly.
It is a fermented protein, which makes it more easily digestible.
The amount of waste from the fish industry is estimated at more than one million tons a year, and in a way, this is a direct result of the use of misos, according to the Environment Ministry.
A lot of it is just waste.
If you take a bag of misosho and put it in the landfill, the amount of misoly is less than a tenth of one percent of that amount, said Masahiro Kato, a fisheries researcher at the Japan Food and Drug Administration.
And that waste is a problem for the fishing industry, he added.
Fish that are caught for misos have to be transported to a factory that then kills the fish.
Kato said that is why he is worried that fishermen are being poisoned by these fish, because the fish are being caught in a factory and then killed for profit.
Fishing nets and fishing nets can also cause pollution, according a study by the Japanese government.
That study showed that one out of every five fish caught for fish in Fukushima is being poisoned, and a study conducted by Greenpeace estimated that the number poisoned in Fukushima had increased to more than 3,500 fish per year.
This is a huge issue that is affecting a lot of communities, Kato told CNN.
And it is really affecting the fishermen.
We have a very large number of fishermen in Fukushima who are working hard to keep their jobs, and they are worried that their livelihoods are being threatened.
