Abstract
In a fish stock delineation study based on MANOVA/MANCOVA of a morphometric data set, use of measurements on many characters will result in a statisti cal artifact generating spurious significant differences between population s. A preliminary method is demonstrated for testing the presence of this ar tifact. Data analyzed for stock identification purposes should employ only a small number of morphometric characters, perhaps three or four. (C) 1999 Elsevier Science B.V. All rights reserved.
