Demersal Species

The accurate identification of genetic partitioning is of primarily importance when devising conservation management strategies for today’s marine resources. The great variety of genetic structure displayed by demersal species underscores the need for the identification of common patterns that can be found across species. Here, we analyse allele frequency variation at 10 microsatellite loci of two congener demersal fish, the red mullet ( Mullus barbatus ) and the striped red mullet ( Mullus surmuletus ), from the Atlantic Ocean and the Mediterranean Sea. The results indicate that two different gene flow patterns exist between these species. The red mullet’s genetic distribution was found to be highly structured, resembling that of a metapopulation composed by independent, self-recruiting subpopulations with some connections between them. The striped red mullet displayed less genetic heterogeneity within the Mediterranean Sea and a substantial gene flow reduction between the Atlantic Ocean and Mediterranean Sea. Our results indicate that gene flow patterns in the demersal environment can be substantially different between closely related species with highly comparable biology, suggesting that biogeographic boundaries can affect demersal species in a different way despite common ecological features and spatial overlap. We conclude that the delimitation of such boundaries could be determined by the fine differences in life history traits between species.

Abstract Maggio, T., Lo Brutto, S., Garoia, F., Tinti, F., and Arculeo, M. 2009. Microsatellite analysis of red mullet Mullus barbatus (Perciformes, Mullidae) reveals the isolation of the Adriatic Basin in the Mediterranean Sea. – ICES Journal of Marine Science, 66: 1883–1891. The red mullet Mullus barbatus is commercially one of the most important demersal fish resources in the Mediterranean. Molecular data on its genetic population structure throughout the Mediterranean are reported. Six microsatellite loci displayed a high degree of expected heterozygosity and a high allele number per locus. The Hardy–Weinberg equilibrium test revealed an overall tendency towards heterozygote deficiency, probably caused by the admixture of various demes. Population differentiation was assessed by analysis of molecular variance (AMOVA) and Bayesian analysis. AMOVA showed that most of the variation was within the population, but the mean value of FST was significant, indicating genetic differentiation among the samples analysed. This differentiation is primarily attributable to the isolation of the Adriatic samples and partly to a weaker substructuring of the populations in the Gulf of Lions, Tyrrhenian Sea, Strait of Sicily, and Ionian Sea. Bayesian analysis also revealed genetic differentiation among the samples analysed, identifying two genetic clusters. The restricted gene flow from and to the Adriatic, also recorded for other fish species, most likely reflects the environmental separation of the Adriatic and suggests that management protocols for the red mullet in the Mediterranean should be revisited.

Abstract Helminthological examinations of the red mullet Mullus barbatus (Linnaeus) (Mullidae) from the Gulf of Hammamet, off Tunisia, revealed the presence of one undescribed gonad-infecting nematode species, Philometra barbata n. sp. (Philometridae). The new species as other congeneric species is mainly characterized by the shape of the caudal mound, the distribution of the caudal papillae and the shape of the gubernaculum with the presence of a dorsal protuberance consisting of two dorsolateral lamellar parts separated from each other by a smooth median field in the male. The new species differs from its gonadinfecting congeners in the body length of male, the length of spicules and gubernaculum. This is the second nominal species of Philometra reported from fishes of the family Mullidae and the 14th from the Mediterranean Sea.

The uncertainty in age estimation by otolith reading may be at the root of the large variability in red mullet (Mullus barbatus) growth models in the Mediterranean. In the MEDITS survey, red mullet age data are produced following the same sampling protocol and otolith reading methodology. However, ageing is assigned using different interpretation schemes, including variations in theoretical birthdate and number of false rings considered, in addition to differences in the experience level of readers. The present work analysed the influence of these variations and the geographical location of sampling on red mullet ageing using a multivariate approach (principal component analysis). Reader experience was the most important parameter correlated with the variability. The number of rings considered false showed a significant effect on the variability in the first age groups but had less influence on the older ones. The effect of the theoretical birthdate was low in all age groups. Geographical location had a significant influence, with longitude showing greater effects than latitude. In light of these results, workshops, exchanges and the adoption of a common ageing protocol based on age validation studies are considered fundamental tools for improving precision in red mullet ageing.
