The elemental chemical composition of salmon vertebrae has been measured by X-ray spectroscopy for two mixtures of stocks. Classification of fish to stock based on this composition has an accuracy in the range of 80–95%. Information on the techniques used, X-ray fluorescence spectroscopy and pattern recognition analysis, is presented for a reader with no background in these areas. The advantages and limitations of this method of stock identification are discussed.Key words: X-ray spectroscopy, pattern recognition analysis, stocks, salmon, management

Elemental Data

X-ray fluorescence spectroscopy is being used to measure the elemental composition of fish tissues. The elemental data are then subjected to pattern recognition procedures in an attempt to discriminate fish stocks.

t was known that historical objects were highly heterogeneous. Due to the complex nature of materials and objects, extremely sensitive, spatially resolved, multi-elemental and versatile analytical instruments were needed. The techniques employed should be as a noninvasive as possible and able to give complementary information from macroscopic to nanometer scales. In this work, X-ray based spectroscopy including energy dispersive X-ray fluorescence spectroscopy (EDS), Proton-induced X-ray emission spectroscopy (PIXE), and micro-beam X-ray fluorescence spectroscopy (µ-XRF) were used to analyze chemical composition of the Lanna-style glass. Microstructure was also studied. It can be concluded that these techniques in combination are powerful for the investigation of heterogeneous glassy materials.
