    Notes: 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.

    Parental effects on size variation in fish larvae (1992)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 41 (1992), S. 0 
    Details

    Notes: The growth and changes in the standard deviation about mean length were measured for sole, Solea solea L., and herring, Clupea harengus L., larvae from crosses of one or two males with one or two females. The sizes of sole larvae did not differ between crosses but the size variation increased faster with age when two females were used. Both maternal and paternal effects were detected for size at hatching in herring, but there was no parental influence on size variation. Size variation in herring larvae declined or was stable during the yolk sac stage and was not affected by the number of parents used for fertilizations.
