Abstract

The usefulness of multivariate morphometrics to distinguish between fed and starved fish larvae was tested on laboratory reared herring larvae (Clupea harengus ). Linear Discriminant Analysis was used to obtain a linear function which separates the two groups of larvae maximally. The calculations were based on twelve morphometric characters, taken individually by means of an image analysing system. A statistically significant separation of fed and starved larvae was obtained. The most important characters and the number of characters necessary for separation are outlined.
