| Abstract: | A microwave fat: water content meter designed for use on pelagic fish has been found to exhibit seasonal changes in calibration. This has been examined in detail for sprats ( Sprattus sprattus ) and herring ( Clupea harengus ) and is ascribed in part to the seasonal changes in these species of the protein content, which influences the rotational mobility of water in the tissue. Various solutions to the problems are proposed. |
