Morphometric variation in 15 characters of the red mullet Mullus barbatus samples from seven Greek localities was examined using multivariate analysis. 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.

    • "Morphometric and meristic morphological characters are used widely to identify fish stocks (Turan et al. 2004), and they remain the simplest, most direct methods of species identification. From previous studies (Creech 1992, Mamuris et al. 1998, Bronte et al. 1999, Hockaday et al. 2000), it is understood that the analysis of phenotypic variation in morphometric or meristic characters is the most commonly used method to delineate stocks of fish. It has often been used in discrimination and classification studies by statistical techniques (Agnew 1988, Avsar 1994). "

    ABSTRACT: This study was designed to evaluate morphological differences between cultured and wild African catfish, Clarias gariepinus (Burchell). Fish samples were collected from the lower Benue River (axis in Makurdi), while cultured fish were obtained from the University of Agriculture Makurdi research farm. The results revealed significant sex-related variation in the fish from different environments. Significant differences were observed in all morphometric parameters measured and in three of the five meristic counts recorded. Discriminant analysis and cluster analysis of morphometric parameters showed a high divergence among the populations, hence the tested fish samples were grouped into respective environments by sex. The meristic count, however, overlapped broadly showing no divergence among the populations. The morphometric differences between the cultured and wild African catfish could have been linked to genetic differences or environmental factors or a combination of both factors.

    • " the southern Aegean Sea (Bilge et al. 2014). Accordingly to previous papers the b value of E. klunzingeri species in the Turkey has been shown to range from 3 to 3.710. Differences in slopes might be a result of differences among the number and length range of specimens examined as well as the effect of area or season (Petrakis and Stergiou 1995).Mamuris et al. 1998)."

    • "Stripped red mullet (Mullus surmuletus, Linnaeus, 1758) and red mullet (Mullus barbatus, Linnaeus, 1758) are distributed in the Eastern Atlantic Sea from North Sea to Senegal as well as throughout the Mediterranean and Black seas (Whitehead et al., 1986). Both are demersal fishes and share very similar biological characteristics (Mamuris et al., 1998); both species spawn in spring, and their larvae and juveniles are pelagic. Notwithstanding, they differ in their habitat preference: while M. surmuletus is mostly found on rough bottoms, M. barbatus instead prefers sandy or/and muddy habitats (Tserpes et al., 2002). "

    ABSTRACT: Population connectivity scales are important tools to achieve a mechanistic understanding of the factors regulating the abundance and distribution of marine populations and therefore support conservation actions to manage fisheries and stocks. We used 10 microsatellites markers on mullets' samples across the Spanish coast to determine the spatial scale of gene flow as well as the origin of post-larvae caught inside two MPAs. Population structure varied from complete homogeneity for Mullus barbatus, to high spatial variability in Mullus surmuletus samples. Differential habitat utilization by species, geomorphological features and oceanographic patterns are discussed as potential causes of patterns observed. Although we were unable to verify the origin of most post-larvae caught inside MPAs we suggest that they may act as genetic reservoirs due to high heterozigosity levels found in adult specimens inside (M. surmuletus) and nearby (both) them. Our results indicate that early life history traits (i.e. larvae) may not be the only determinant on species dispersal capability, suggesting that other mechanisms such as fine scale adult or juvenile movement may have been underestimated as promoting population connectivity.
