The object was to characterize possible population differences that would account for previously reported differences in behavioural patterns observed in commercial fishing activity.
Genetic analysis of 27 enzyme systems yielded only fifteen useful loci of which fibre had allele variants, but only two of them were polymorphic within 95%.
Morphometric analysis of nine body and appendage measurements revealed significant differences between sampling sites in scaphocerite length, uropodal length, and the length of the articles on the third walking leg.
The samples analysed genetically could not be differentiated, but morphological differences were compared between different hydrographic regions of the Mediterranean Basin.

Introduction Aristeus antennatus (rose shrimp) is an important crustacean resource in the fisheries ` 1987; Cartes and Sarda, ` 1993; and ecology of the Mediterranean Sea (Tobar and Sarda, Demestre and Lleonart, 1993; Cartes, 1994).
This species ranges from the adjacent Atlantic waters off Morocco and Portugal to Israel at depths between 300 and 2200 m *Corresponding autho...
