“…The heterozygosity values of from 0.043 to 0.066 in the A. antennatus samples obtained in the present study corroborate the low genetic variability already reported in penaeids (Lester, 1979;Nelson and Hedgecock, 1980;Tam and Chu, 1993). In addition, the very low values for F and ST genetic distance provide evidence about no population structure among the samples.…”

“…Functional morphometrics has been studied (Sarda et al, 1995) and has revealed the adaptive effects of certain body parts on the swimming and feeding behaviour of the different size groups and between the sexes, but no other studies on population differentiation have been carried out on the basis of morphometric changes. On the other hand, some biochemical genetic studies have been performed on penaeids (Lester, 1979;Hedgecock et al, 1982;Tam and Chu, 1993) but no electrophoretic data have been reported for the rose shrimp until now. This paper presents the first comparative morphometric and biochemical genetic study on A. antennatus in its distribution area in the Mediterranean Sea and the adjacent Atlantic Ocean region.…”

Eleven samples of rose shrimp (Aristeus antennatus) from different areas of the Mediterranean Sea and adjacent Atlantic waters were subjected to morphometric and electrophoretic analyses. The object was to characterize possible population differences that would account for previously reported differences in behavioural patterns observed in commercial fishing activity. Genetic analysis of 27 enzyme systems yielded only fifteen useful loci of which fibre had allele variants, but only two of them were polymorphic within 95%. Morphometric analysis of nine body and appendage measurements revealed significant differences between sampling sites in scaphocerite length, uropodal length, and the length of the articles on the third walking leg. The samples analysed genetically could not be differentiated, but morphological differences were compared between different hydrographic regions of the Mediterranean Basin.

“…The obtained F ST values was higher than those reported for P. setiferus (F ST =0.017) [25], P. duorarum (F ST =0.0175) [25], but lower than those reported for P. monodon(F ST =0.031) [26], P. kerathurus (F ST =0.040) [27]. Low levels of the coefficient of gene differentiation may due to high level of gene exchanges among the populations.…”

Genetic diversity was investigated using assay of vertical slab ployacrylamide gel electrophoresis for the nine populations of Fenneropenaeus penicillatus. The results showed high levels of genetic diversity in each of the nine F. penicillatus populations. The mean number of alleles per locus ranged from 1.3333 to 1.6667, with a average of 1.4148. And the mean effective number of alleles per locus ranged from 1.1447 to 1.2094, with a average of 1.1664. The average of percentage of polymorphic loci was 26.67%, ranging from 13.33% to 40.00%. The average of observed heterozygosity was 0.1380, ranging from 0.1311 to 0.1511, and the average of expected heterozygosity was 0.0866, ranging from 0.0720 to 0.1023. The coefficient of gene differentiation among populations is low, indicating that only 2.09% of the total genetic diversity comes from inter-population, while the remaining 97.91% comes from intra-population differences. The genetic distance among populations is 0.0002～ 0.0049 and gene flow among the populations is large. The results suggest that genetic structure is very similar among the nine F. penicillatus populations studied.

“…Biochemical approaches to the study of the systematics and population genetics of the Penaeidae, using allozymes, has previously led to the conclusion that the morphological similarity of the group is mirrored by a low level of genetic polymorphism (e.g., Lester, 1979;Redfield et al, 1980;Mulley and Latter, 1980;Sunden and Davis, 1991;Benzie et al, 1992;Tam and Chu, 1993). However, Palumbi and Benzie (1991) discovered high levels of molecular divergence between Penaeus stylirostris, P. vannamei, P. esculentus, and Metapenaeus endaevori, as revealed by partial sequencing of 12S and COI mtDNA regions.…”
