Abstract We review a numerical method of associating fish of unknown stock affiliation with their respective spawning stocks on the basis of differences in quantified scale shape. Magnified images of fish scales are digitized and the shapes of the scales are transformed into a mathematical relationship (Fourier series), from which the original shape can be regenerated with little loss of resolution. A multiple, stepwise discriminant analysis is used to characterize each putative stock within a… CONTINUE READING
