Title: Scientists say contamination of ocean fish minimal so far

The massive radioactive fallout from the Fukushima No. 1 nuclear plant has sparked fear in seafood lovers and commercial fishermen both at home and abroad, and some worry the contamination could pass through and even become more concentrated in the ocean food chain.

[…] experts stress that close monitoring of bottom fish off Fukushima should continue because there’s no telling when contamination levels will peak. […]

Takashi Ishimaru, professor of ocean science at Tokyo University of Marine Science and Technology

  • Contaminated plankton and waste from fish naturally sink to the seabed and are then eaten by miniscule benthos organisms, which bottom fish feed on
  • As a result, radioactive materials are passed up the food chain.
  • “Radioactive materials circulate at the bottom of the ocean. . . . It won’t be reduced easily”
  • Researchers have yet to obtain data on how contamination from the Fukushima No. 1 plant has spread along the sea floor, so consumers should keep a watchful eye on bottom fish
  • “There could be hot spots under the sea”
  • “If hot spots exist on the ocean floor, contamination levels of fish that inhabit such areas may spike”

Satoshi Katayama, professor of fisheries biology and ecology at Tohoku University

  • “(Contamination) levels of freshwater fish and seabed fish such as flounder haven’t declined”
  • “It’s hard to say the contamination peak among such fish has passed”

Ibaraki Prefecture

[…] beach seine fishing off northern Ibaraki Prefecture was halted late last month.

Gunma Prefecture

Meanwhile, samples of freshwater fish caught in Fukushima and Maebashi, Gunma Prefecture, have revealed high levels of contamination exceeding the government limit. Tests conducted between April 19 and Jan. 10 in Gunma on 34 freshwater fish showed that 11 caught in Lake Onuma exceeded the maximum level.

Tochigi Prefecture

In Tochigi Prefecture, meanwhile, “ayu” (sweet fish) caught in May in the Kinugawa River near the city of Utsunomiya and the Nakagawa River near the town of Motegi contained radioactive cesium above 400 becquerels per kilogram — less than the current provisional limit but four times higher than the new limit the government will introduce in April.

    Yes, just HOW did the contamination reach the ocean bed? Curious minds would like to know.

    Could it possibly be that all the reactors have hollow bottoms and those pesky isotopes have migrated to the ocean?

    China continues research on Fukushima radiation in Pacific Ocean

    “China conducts second radiation monitor in Pacific Ocean By Yu Jianbin (People’s Daily Overseas Edition), December 29, 2011 Edited and translated by People’s Daily Online A marine monitoring team dispatched by China’s State Oceanic Administration accomplished the mission of monitoring radiation in the western Pacific Ocean for the second time, and returned to Xiamen on Dec. 27 aboard the Xiangyanghong 09 scientific exploration ship.

    The monitoring team sailed about 6,100 nautical miles in 30 days, and monitored radiation in the air over and water in the western Pacific Ocean as well as radiation-sensitive sea creatures, chemistry and dynamic environments.

    This is the second time that China has monitored radiation in international waters in the western Pacific Ocean.”

    “inadequate monitoring of Fukushima radiation in ocean

    Buesseler has already reported some results from the 15-day cruise last May and June….. ”It implies the groundwater is contaminated or the facility is still leaking radiation.”

    ”There is no safe level of radiation. They should be making every effort to monitor food.”.

    wonder what this means? how is it used?

    “The intellectual properties have socio-economic as well as scientific value that should be transferred to society in an appropriate manner. ”

    from this

    “Handling of Data and Samples as Intellectual Property Some of the Data and Samples must be protected as intellectual properties, which will be identified by JAMSTEC whenever applicable.
    The intellectual properties have socio-economic as well as scientific value that should be transferred to society in an appropriate manner. In accordance with its “Basic idea for Intellectual Properties of JAMSTEC,” JAMSTEC will promote appropriate use and management of the Data and Samples identified as intellectual properties.”

      feckin jemstec link.. both browser keep crashing talking about a third party exception… when i try to down load the pacific reports.. the 2004 (latest on offer) merde! first the nrc now jamstec!! grr! hope someones backing this stuff up?? the nukies are getting desperate!!

  • Could be ?? To tell or not to tell the people the fish are subject to poison everyone eating from the Pacific Ocean period !
    Fishing Industry come to an abrupt halt, millions out of work, food supplies have to be harvested from other regions of the world to satisfy demand, what will China/Vietnam and other Asian countries do with already diminishing fish supplies in recent years having to go hundreds of miles off shore risking lives against typhoon’s to provide a staple food source to it’s people !

    Either the foodstuffs are contaminated or not. Whether it exceeds govt levels or not is irrelevant… the Govt has proven it does not care about its peoples. WHY would you trust your Govt with your health and safety anymore? HOW can we trust our Govts anymore?

    You would eat fish if it had a little shit on it would you? I’m thinking radiation is at least as bad as shit!

    WHY IS THERE NO REAL DATA ON THE BIGGEST CONTAMINATION EPISODE IN HUMAN HISTORY (not counting the “unknown gulf episode)

    oceanographical scientists are currently trying to get funding from the obominator to check the bit of the pacific that corresponds with oil drilling.. there is no guarantee they will get this research money.. they have to keep quite about the nuclear stuff because it falls under the military domain.. not even the obominator is going to mess with that “mother….” !

    so to recap.. military say no testing for isotopes.. we get no testing for isotopes… and i cant imagine that many oceanographical scientist are too happy about that! but what can they do with so little funding on offer? they could go to… Oh!! 🙁 poop!!

    It galls me that the fish tested and claimed as safe, representing the general fish population off Fukushima, are all migratory fish that just entered the region.

    And remember, the safe levels are due to drop in April to 100 Bq/kg, rendering the 500 Bq/kg limit used in this study as dangerous.

    Sleight of tongue……

    • Pallas89juno Pallas89juno

      Dosdos, and as you know, chances are that none of the fish tests were actually either properly tested, were inaccurate, or the results are total lies. I vote for the total lies knowing well how government and corporate systems work. Why would we ever believe anything the Japanese government, corporations or U.S. same, every say? lol
