    Peter,

    I obtained the data from "Chemical Changes of Trimethylamine Oxide During
    Fresh and Frozen Storage of Fish" by Joe M. Regenstein, Mary Anne Schlosser,
    Allan Samson and Michael Fey in Chemistry & Biochemistry of Marine Food
    Products, 1982. Originally, the data was presented in parts per billion
    (ammonia - 110,000 ppb; TMA 600 ppb) but I have memorized it as ppms. The
    authors had cited after S. Ikeda and his presentation given at the Torry
    Conference in 1979 in Aberdeen, Scotland. The Ikeda's paper from the
    conference was published In Advances in Fish Science and Technology, J.J.
    Connell et al but I am not sure whether the publication would contain those
    particular references.

    Best regards,

    Andrew Strak
