ANOVA, stepwise discriminant analysis and cluster analysis revealed a rather high morphological variability between the populations studied. The discriminant analysis revealed that about 80% of the examined fish could be correctly classified into the seven areas. This variability could be explained in terms of genetic structuring of the populations and/or environmental conditions prevailing in each geographic area in combination with fish migration and egg/larvae transportation from one area to another. The results suggest that multivariate analysis when combined with other important biological parameters of red mullet may have important implications for the management of the Greek demersal fish resources.10aGreek marine waters10amorphometrics10aMullus barbatus10amultivariate analysis10aPisces1 aMamuris, Z.1 aApostolidis, A.P.1 aPanagiotaki, P.1 aTheodorou, A.J.1 aTriantaphyllidis, C.  uhttps://icgf.myspecies.info/content/morphological-variation-between-red-mullet-populations-greece02079nas a2200241   4500008004100000245013700041210006900178260001200247300001200259490000700271520123800278653001501516653002001531653002201551653001101573653001901584653002601603653002201629653002101651100002001672700002001692856012501712       1997                        eng d00aThe foraging ecology of two pairs of congeneric demersal fish species: Importance of morphological characteristics in prey selection0 aforaging ecology of two pairs of congeneric demersal fish specie  c1997///  a324-3400 v503 aThe feeding habits of two sympatric species pairs of demersal fish (Mullus barbatus Mullus surmuletus. Serranus cabrilla Serranus hepatus) which occupy the shallow coastal area (25 30 m) in Iraklion Bay were investigated from samples collected on a monthly basis (August 1990 to August 1992). Stomach content analyses revealed that all of them were carnivores, feeding mainly on benthic invertebrates, and that each species consumed a narrow range of prey species with no significant dietary overlap. The morphology of their feeding apparatus was compared to examine the effect of any morphological differences on food selection and resource partitioning between the fish species. The species could be distinguished on the basis of the size of their mouth gape, the number of gill rakers and the length of their intestine. This study shows that each species pair follows a different strategy segregating along food niche dimensions. In particular, M. barbattus and M. surmuletus segregate their feeding niche consuming different prey taxa with similar sizes whereas S. cabrilla and S. hepatus differ considerably with respect to the degrees to which prey species contribute to their diets coupled with differences in mean prey sizes.10amorphology10aMullus barbatus10aMullus surmuletus10aPisces10aprey selection10aresource partitioning10aSerranus cabrilla10aSerranus hepatus1 aLabropoulou, M.1 aEleftheriou, A.  uhttps://icgf.myspecies.info/content/foraging-ecology-two-pairs-congeneric-demersal-fish-species-importance-morphological
