“…Rosenblatt & Waples (1986) and Rossi et al (1998) asotiropoulos et al, 2001), and between Liza affinis and M. cephalus (0.917; Lee et al, 1995). In contrast, comparison made between intergeneric species provided D values lower than those referred for congeneric species (0.523 for M. cephalus vs. L. subviridis; Menezes et al, 1992). Caldara et al (1996) found less interspecific differences in the mtDNA sequences between the genera Liza and Chelon than within the genus Liza.…”

“…Caldara et al (1996) used mtDNA sequence analysis and also found the lowest genetic distance between C. labrosus and L. saliens. Menezes et al (1992) also clustered two different genera (M. cephalus and L. subviridis) as closest taxa. Based on our data set, monophyly of the genus Liza was not supported, allowing room for the plea to get more data to resolve the systematics of mullets.…”

“…The separation of Liza, Chelon and Oedalechilus might be unnatural, and the monophyletic origin of the genus Liza is questionable. The existence of such disorder in phylogenetic studies of Mugilidae in the literature is not uncommon (Cataudella et al, 1974;Menezes et al, 1992;Caldara et al, 1996;Papasotiropoulos et al, 2002). The lack of congruence in the phylogenetic relationships of mullet species suggests that the present status of Mugil species requires additional molecular genetic analyses based on different parts of the genome.…”

Phylogenetic relationships among four genera and nine species (Mugil cephalus, Mugil soiuy, Liza ramada, Liza aurata, Liza abu, Liza saliens, Liza carinata, Chelon labrosus, Oedalechilus labeo) of the Mediterranean mullets (Mugilidae) were investigated by means of allozyme electrophoresis using a seven-enzyme system (CK*, GAPDH*, G3PDH*, IDHP*, ME*, MDH*, PGM*) comprising eleven putative loci. The highest genetic divergence was 1.299, detected between M. cephalus and L. aurata and the lowest (0.280) was found between L. carinata and L. saliens. The amount of genetic divergence between the genera Chelon and Oedalechilus did not appear to be high (0.285). In a UPGMA tree, all nine species were grouped in two main branchings. In the first branch, C. labrosus and O. labeo clustered as closest taxa and were sister group to L. ramada. The other four Liza species produced two sub-branching in this group; L. carinata branched together with L. saliens, and L. aurata branched together with L. abu. In the second branch the two species of the genus Mugil, M. cephalus and M. soiuy, clustered together and were clearly isolated from the other three genera.

High genetic diversity, large inter‐oceanic divergence and historical demography of the striped mullet

The striped mullet Mugil cephalus L. is a circumtropical species whose extreme conservative morphology stands in contrast with the degree of genetic differentiation at a global scale. One hundred and fourteen mitochondrial control region DNA sequences were analysed from four localities in the Gulf of Mexico (Texas, Louisiana, Mississippi, Florida), one on the U.S.A. east coast (N. Carolina), and one in Hawaii, giving very high levels of molecular diversity (h=1·0 every haplotype was unique in all samples, =1·1-2·0% in Gulf-Atlantic and =3·1% in Hawaii). With no genetic evidence of dramatic population expansions, mismatch distributions were still very different in each ocean. Stable population levels in Hawaii have fostered the generation and persistence of very high molecular diversity, but Gulf-Atlantic samples suggest a shorter span of population stability. Ninety-five per cent of the molecular variance was allocated between ocean basins and virtually none among Gulf-Atlantic samples. A neighbourjoining reconstruction revealed Atlantic-and Pacific-specific lineages separated by more than 24% uncorrected sequence divergence (d=0·49 Tamura-Nei Gamma-corrected). The lack of phylogeographic structure among Gulf-Atlantic samples corroborated the AMOVA results and supported the existence of a single population with high levels of gene flow along the Gulf of Mexico and north-west Atlantic coasts. The genetic differentiation between oceans points to the absence of gene flow and an accelerated rate of mitochondrial evolution in the genus Mugil. 2000 The Fisheries Society of the British Isles

“…It is considered an important source of animal protein for the peoples of the Pacific Basin, Southeast Asia, India, the Mediterranean, Eastern Europe and, many parts of central and South America (Lee and Tamaru, 1988). The identification of the fry to be used for stocking purposes is of practical interest and often causes problems for farmers who want to stock the ponds with specific species (Menezes et al, 1992). Different methods are used for identification but phenotype based on morphometric and meristic is considered as earliest and authentic methods for the identification of fish species in fish biology to measure discreteness and relationships among various taxonomic categories.…”

This study aimed to study the phenotype and genotype differentiation and to compare the amount of differences in phenotype based on morphometric character indices and meristic counts with the amount of differences in genotype based on random amplified polymorphic DNA (RAPD) fingerprinting between two Mugilidae, Flathead grey mullet (Mugil cephalus) and Thinlip grey mullet (Liza ramada). The results showed that there were significant differences in most of the morphometric character indices but no significant differences were detected in most of the meristic counts between M. cephalus and L. ramada. In addition, the euclidean distance between M. cephalus and L. ramada using hierarchical cluster analysis of quantitative phenotype based on morphometric character indices and meristic counts and condition factor was (0.421). Genotype analysis based on RAPD fingerprint showed highly genetic dissimilarity (0.437) between M. cephalus and L. ramada. These results confirmed that the amount of differences in genotype reflected the same amount of differences in phenotype between M. cephalus and L. ramada. Therefore, either phenotype analysis can be use based on a large number of morphometric character indices and meristic counts or genotype analysis based on RAPD fingerprinting to discriminate M. cephalus and L. ramada with the same results.
