“…The expected heterozygosity (He) values varied from 0.761 ± 0.014 (Santa Cruz Arriba, 2003) to 0.841 (Caimito, 1995 andRosario, 2003). These diversity parameters were indicative of a high polymorphism and were in the range of those reported for other penaeid species analyzed with microsatellites (Benzie 2000;Xu et al 2001;Ball and Chapman 2003;Maggioni et al 2003;Borrell et al 2004).…”

We analyzed the spatiotemporal genetic structure of Farfantepenaeus notialis populations using five microsatellites loci in order to understand the influence of natural events such as hurricanes on the genetic drift/migration balance as the main cause for the variation of allele frequencies over time. The results were compared with the previous ones obtained from allozymes and mtDNA. High and stable genetic diversity levels (He=0.879+/-0.0015) were found over eight years for the populations that inhabit the south Cuban platform, however significant changes of allele frequencies were detected over time. The F(ST) estimates, albeit low, revealed significant differences among populations inside the Ana Maria Gulf for 1995 but not for the 1999 and 2003 samples. The F(ST), AMOVA and the genetic distance analysis revealed the instability of the genetic structure over time in accordance with allozymes results. The correspondence of the microsatellite results with those obtained from allozymes confirm the effects of migration enhanced by natural events as the main cause of the temporal variation of allele frequencies. The genetic drift effect was discarded through the evaluation of Ne and the M ratio, while natural selection effects were rejected because of the lowest probability of microsatellite loci being under selective pressures. The microsatellite data are also consistent with the results obtained with mtDNA in detecting significant and persistent genetic differences between the Gulfs of Ana María and Batabanó for the years 1995 and 2003.

“…Past studies on shrimp have shown significant allelic variation for microsatellite loci between farmed and wild populations (WOLFUS et al, 1997;XU et al, 2001;BORRELL et al, 2004, LUAN et al, 2006. Heterozygosity and the number and distribution of alleles are important for variability estimations (BEARDMORE et al, 1997).…”

Genetics of two marine shrimp hatcheries of the Pacific white shrimp Litopenaeus vannamei (Boone, 1931) in Pernambuco, Brazil

et al. 2010

The shrimp industry has grown significantly over the past 10 years in Brazil, especially the farmed production of the exotic Pacific white shrimp, Litopenaeus vannamei. In 2004, this industry was marked by a productivity crisis, which stirred interest towards genetic improvement of shrimp stocks. Shrimp breeders importation was banned in Brazil by a govern Normative Instruction in 1997, as a sanitary precaution. Since then, broodstock replacement in hatcheries has been based on domestic stocks, raising concerns on the decline of genetic diversity and if the existing diversity would allow effective genetic improvement programs. In the present research, genetic parameters such as number of alleles, effective allele number, expected and observed heterozygosities, inbreeding coefficient, genetic differentiation index and deviation from Hardy-Weinberg equilibrium have estimated of two important commercial hatcheries in Northeast Brazil, genotyping 5 microsatellite loci. Effective allele number (3 to 10.5) and average observed and expected heterozygosities (0.480 and 0.680) were consistent with those reported for cultured and wild Penaeid populations. However, F IS positive values (0.381 for hatchery A and 0.249 for hatchery B) reflected a significant heterozygous deficiency within hatcheries (P<0.01). Nevertheless, we concluded that even after ten years of limited genetic input, it has been possible to maintain a high level of genetic variability, possibly due to the wide diverse origin of the founder broodstocks and the constant breeders exchange among hatcheries.

“…Its approximate surface is 20,850 km 2 with an average depth of 6 m. The coastal area is predominantly fringed by mangrove forests and the bottom is extensively covered by seagrass-beds with varying densities of Thalassia testudinum. Biological studies have shown signs of environmental degradation in the Gulf through loss of biodiversity, shift of benthic communities (Cruz et al, 2001;Hernandez-Zanuy and Carballa, 2001;Baisre et al, 2003) and reduction in size and capture levels of the spiny lobster Panulirus argus (Puga et al, 1996;Borrell et al, 2004). Panulirus argus is the most valuable species for the fishing industry http://dx.doi.org/10.1016/j.chemosphere.2015.05.044 0045-6535/Ó 2015 Elsevier Ltd. All rights reserved.…”
