“…Although the genetic distances for the five L. vannamei broodstocks were close to zero (0.2 to 1%) the values were similar to those published by Gusmão et al (2000) for some penaeid species investigated using COI gene sequencing. In addition, in our study the mean genetic distance between L. vannamei and F. subtilis was 10.94%, which was close to the 8.1% genetic distance obtained by Gusmão et al (2000) for Farfantepenaeus paulensis and F. subtilis.…”

“…The COI region sequences exhibited sufficient nucleotide diversity to be able to determine the occurrence of one haplotype per broodstock and another for F. subtilis, with 8 divergent sites being detected among the five broodstocks and 70 between L. vannamei and F. subtilis. The substitution rate presented by the COI gene was somewhat higher, allowing the detection of genetic differences between different populations of the same species (Conn, 1998;Lee, 2000;Gusmão et al, 2000). Although the genetic distances for the five L. vannamei broodstocks were close to zero (0.2 to 1%) the values were similar to those published by Gusmão et al (2000) for some penaeid species investigated using COI gene sequencing.…”

“…In addition, microsatellites analyses have not been able to find isolation by distance in populations of Litopenaeus schmitti from eight different localities on the Brazilian coast (Maggioni et al, 2003). Similar results have been obtained by Gusmão et al (2000) for Farfantepenaeus brasiliensis populations using allozyme analysis.…”

“…Mitochondrial DNA (mtDNA) shows a high level of polymorphism and an evolutionary rate 10 times faster than nuclear genomes and is subject to maternal and asexual inheritance (Awadalla et al, 1999), characteristics which make mtDNA very useful for genetic studies in aquaculture (Allegrucci et al, 1998). Sequence analyses of mtDNA have been widely used in phylogenetic studies of natural shrimp populations (Bouchon et al, 1994;Baldwin et al, 1998;Klinbunga et al, 1999;Gusmão et al, 2000;Maggioni et al, 2001) and to evaluate genetic divergence between captive populations (Iguchi et al, 1999;Sekino et al, 2002). The 16S rRNA gene is found in the conserved portion of the mtDNA and has been extensively used in phylogenetic studies while the cytochrome oxidase I (COI) gene, which seems to be less conserved than the 16S rRNA gene, has been frequently used in evolutionary studies (Clary and Wolstenholme, 1985;Beard et al, 1993).…”

In the constantly growing Brazilian shrimp industry the evaluation of genetic relationships between broodstocks is an useful tool for shrimp culture management programs. We established the genetic relationships between five broodstocks of the white marine shrimp Litopenaeus vannamei (Penaeidae) based on the sequencing of the mtDNA 16S rRNA and cytochrome oxidase I (COI) regions. Although no divergence was found between the broodstocks for the highly conservative 16S rRNA gene, we did find an 8.2% distance between L. vannamei and the Farfantepenaeus subtilis. Analyses of the COI region showed genetic distances of only 0.2 to 1% between the broodstocks, which contrasted with the 10.9% mean distance found between L. vannamei and F. subtilis. The small genetic distance values obtained may be related to genetic drift or a founder effect that occurred during broodstocks establishment. The mtDNA analysis was able to characterize the genetic divergence between the broodstocks studied and could be helpful for defining better management strategies of these crustacea.

“…However, genetic studies of natural populations of Brazilian shrimps have been conducted only for the genera Farfantepenaeus and Litopenaeus (e.g., Gusmão et al, 2000;Maggioni et al, 2001;Gusmão et al, 2004). In addition, until now, despite its economic importance, the genetic structure of populations of X. kroyeri has never been studied.…”

Genetic structure of the sea-bob shrimp (Xiphopenaeus kroyeri Heller, 1862; Decapoda, Penaeidae) along the Brazilian southeastern coast

The sea-bob shrimp, Xiphopenaeus kroyeri, is one of the most important economic marine resources along the entire Brazilian coast. Nevertheless, despite its economic importance, no studies have examined the population genetics of this species. In this paper, we used ten allozyme loci to study the pattern of genetic structuring in X. kroyeri along the southeastern Brazilian coast. Seven of the ten analyzed loci were polymorphic, yielding observed heterozygosity values higher than those reported for other penaeid shrimps. The population from São Paulo was significantly different from the other two populations (Rio de Janeiro and Espírito Santo), which, in turn, seem to form a single panmitic unit. Therefore, our results clearly indicate that conservation policies for this species should consider the São Paulo population as an independent stock from those of Rio de Janeiro and Espírito Santo.

Splitting of the genus Penaeus sensu lato into six new genera based on morphological features alone has been controversial in penaeid shrimp taxonomy. Several studies focused on building phylogenetic relations among the genera of Penaeus sensu lato. However, they lack in utilizing full mitochondrial DNA genome of shrimp representing all the six controversial genera. For the first time, the present study targeted the testing of all the six genera of Penaeus sensu lato for phylogenetic relations utilizing complete mitochondrial genome sequence. In addition, the study reports for the first time about the complete mitochondrial DNA genome sequence of Fenneropenaeus indicus, an important candidate species in aquaculture and fisheries, and utilized it for phylogenomics. The maximum likelihood and Bayesian approaches were deployed to generate and comprehend the phylogenetic relationship among the shrimp in the suborder, Dendrobranchiata. The phylogenetic relations established with limited taxon sampling considered in the study pointed to the monophyly of Penaeus sensu lato and suggested collapsing of the new genera to a single genus. Further, trends in mitogenome‐wide estimates of average amino acid identity in the order Decapoda and the genus Penaeus sensu lato supported restoration of the old genus, Penaeus, rather promoting the creation of new genera.
