Abstract

Stock differentiation studies of sprat (Sprattus sprattus phalericus Risso) from the Black Sea coast of Turkey have been carried out morphometrically and meristically applying the generalised distance of Mahalanobis (GDM) and also physiologically using three-level nested ANOVA (TLNA). Fifteen morphometric measurements, together with nine meristic counts and fat concentration of wet tissues of sprat have been used in the analyses of GDM and TLNA, respectively. Insufficient differences in general phenotypic, genotypic (P>0.01) and physiological (P>0.05) characteristics implied the existence of a single unit stock. Samples collected in the same period showed greater similarity than those taken from the same areas in different periods.
