“…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 study of the genetic characteristics of shrimp species and the analysis of genetic relationships between broodstocks can be an useful tool for their management because genetic identification and discrimination of broodstocks are essential to successful rearing programs (Allegrucci et al, 1998;Sekino et al, 2002).

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.

“…Studying the genetic characteristics of shrimp samples and analyzing the genetic relationships between the breeders can be a suitable tool for managing gene-tic identification and genetic differences in breeding programs (Allegrucci et al 1998, Sekino et al 2002. Maintaining genetic diversity in shrimp populations requires the presence of genetic diversity in stocks in hatchery centers, similar biological patterns, and the use of wild and natural genetic resources (Williams & Johnson 2013).…”

The aim of this study was a detection of different populations of Pacific white shrimp (Penaeus vannamei Boone, 1931) farmed broodstocks and to determine their genetic indexes in hatchery centers of Bushehr province. DNA was extracted from the muscle tissue of 30 broodstocks of 11 stocks using a commercial kit. The repeated sequences were amplified using ten specific primers by PCR in the Iranian Shrimp Center. The results showed that the number of alleles was 4.5-5.5 in the studied stocks. The most allele frequency was observed in the farmed broad stocks of the third stock in the H2 hatchery center, 5.2 ± 0/359. Also, the average of observed heterozygosity in the farmed broad stocks of the second stock in the H5 hatchery center obtained 0.669 ± 0.152, more than other stocks in all centers. Genetics indexes of the farmed broad stocks of the third stock in the H2 hatchery center were increased compared with other stocks in Bucher province. The inbreeding coefficients of the first stocks in the H1 and H3 hatchery centers were significantly more than others, respectively, 0.595 ± 0.105 and 0.547 ± 0.145. The increased inbreeding coefficients of the farmed broad stocks in these stocks can be referred to due to the small size of the founder population and biased selection programs. However, this amount is acceptable according to the information of the other hatchery centers in Bushehr province and other countries. Moreover, it was concluded that broodstock with higher diversity should be used to increase the genetic indicators in the hatchery centers.

Morphometrics and Mitochondrial DNA Genes Analysis Suggest a New Species of Penaeus (Crustacea: Penaeidae) from the Persian Gulf

There are two morphotypes of Penaeus semisulcatus described hitherto in the Persian Gulf, namely the banded and non-banded antennae morphotypes. In this study, we used morphometric measurements and two mitochondrial genes (16S rRNA and cytochrome oxidase subunit I-COI) to assess relationships between the two morphotypes of P. semisulcatus. Out of 25 morphological characters examined, 10 characters were found significantly different between the two morphotypes when tested against separate sexes or both sexes combined. Results from the 16S rRNA and COI sequence analysis of two morphotypes of P. semisulcatus morphotype showed up to 6% and 17% sequence divergence, respectively. The 16S rDNA and COI sequences of the non-banding morphotype were not only very different to those of the banding morphotype but was also very different to all other Penaeus species (i.e., P. monodon, P. merguiensis, and P. indicus) included in the study. Both parsimony and Neighbor-Joining trees based on 16S rDNA and COI sequences provide similar tree topology that clearly separated the two morphotypes into two distinct groups. Based on these findings, we propose the two morphotypes of P. semisulcatus to be relegated as two sympatric species.
