spent-nuclear-fuel reprocessing plant was constructed in Rokkasho in 2008, the site of the underground nuclear-waste repository for the HLW and LLW has not yet been decided. Some local cities announced a plan to conduct an environmental study at the disposal site, but citizens' groups strongly oppose the plan. Fishery and whaling In Japanese diets, fish and its products are more prominent than other types of meat, so much so that fish consumption in Japan has been noted to be the highest in the world at times. In a fact sheet released by the FAO in 2010, it highlighted that with the exception of 2007, Japan has been the leading importer of fish and fishery products since 1970s. Even in today's market, Japan, is the third largest single market in the world for fish and fish products. It is estimated that in 2008 that Japan eat 81 percent of the worlds fresh tuna. These reasons are why Japan has one of the most overfished waters in the world. By 2004, the number of adult Atlantic Bluefin Tuna capable of spawning had plummeted to roughly 19 percent of the 1975 level in the western half of the ocean. Japan has a quarter of the world supply of the five big species: bluefin, southern bluefin, bigeye, yellowfin and albacore. As of 2005, more than ten species faced serious stock depletion. Moreover, the authorities has started to implement stock rebuilding plans for mackerel, snow crab, sailfin sandfish, Japanese anchovy, tiger puffer, and several other species, as stock diminished to depletive measures. These stock rebuilding plans were essential, because data shown by Japan's Ministry of Agriculture, Forestry and Fisheries highlights that mackerel stocks in the northern Sea of Japan were around 85,000 tonnes compared to 800,000 tonnes or so in the 1990s. However, because of the depletion of ocean stocks in the late 20th century and government intervention, Japan's total annual fish catch has been diminishing rapidly. Government policy that has been implemented include The Total Allowable Catch System (TACs). This was ratified by the Japanese government and a law simply known as the TAC law came into place on the 14th June 1996, which essentially sets quotas on the amount that fisheries are allowed to catch, together this coupled with the stock rebuilding plans is slowly reversing years of overfishing that has happened in Japanese waters. Whaling for research purposes continued even after the
