Content descriptions

Bibliography, etc. Note: Includes bibliographical references.
Summary, etc.: Fish production assessment and life history studies frequently use preserved specimens of fish to provide morphometric information when fresh samples are not available. Measurement errors associated with preservation techniques can be corrected if a factor specific to the preservation method is available. The purpose of this report is to develop a correction factor that can be used to obtain an approximation of the pre-preservation length of juvenile sockeye salmon that have been preserved in isopropyl alcohol after a period of fixation in formalin. The report describes the methodology used to determine the length reduction in samples of preserved juvenile sockeye and presents a correction factor recommended for use when examining lengths of sockeye fry (24-40 millimetres only) from the Stuart Lake stock in British Columbia.
