“…The present study demonstrates that P. magdalenae has a high genetic diversity, He = 0.877, compared to that observed for other species of the genus (Santacruz, 2003; Hatanaka et al , 2006; Galzerani, 2007; Carvalho-Costa et al , 2008; Silva, 2011; Rueda et al , 2011) and to other commercially important species that have the same reproductive pattern and migrate long distances (Sanches, 2007; Batista, 2010; Dantas, 2010) (Table 4). Likewise, the microsatellite genetic diversity was slightly lower than that reported by Aguirre et al (2013) for mitochondrial DNA (mtDNA control region) in P. magdalenae (HD = 0.997). These results demonstrate the vagility of the P. magdalenae , in which the strong migratory behavior facilitates the maintenance of high levels of genetic variability, as in species of the genus Prochilodus (Lassala and Renesto, 2007; Santos et al , 2007).…”

Prochilodus magdalenae is an endemic freshwater fish that occurs in the Magdalena, Sinú and Atrato hydrographic basins. It has an important economic role and is a food resource for the artisanal fishing communities. Its socioeconomic importance contrasts with the current status of its fisheries, where stocks are being depleted. Considering its importance and lack of information on its genetic structure, we used seven microsatellite markers to assess the genetic structure of wild populations of P. magdalenae. The genetic diversity was assessed and the population genetic structure was estimated through Fst, analysis of molecular variance and Bayesian analysis. A total of 290 alleles were found in all loci throughout all population. The high polymorphism contrasts with the levels of observed heterozygosity (Ho = 0.276), which are the lowest values recorded for the family. We found three populations of bocachico coexisting throughout the studied system, contradicting the hypothesis that freshwater migratory fish form panmictic populations. These results on the genetic structure of P. magdalenae constitute tools for a better understanding of the behavior and biology of this species, contributing to fish management and conservation programs.

“…Notably, most of the different mitochondrial haplotypes obtained in this study were singletons (65 %), although present in only one sample. A high number of unique haplotypes and high haplotypic diversity levels are features commonly observed in mtDNA studies of Neotropical migratory fish (Martins et al 2003;Batista and AlvesGomes 2006;Santos et al 2007;Garcez et al 2011;Aguirre-Pabón et al 2013). This pattern seems to be related to the large effective population size maintained in migratory species such as P. lineatus ).…”

“…This situation could occur, for example, in the Porto Primavera Reservoir and its tributaries. Some authors have suggested that Prochilodus Agassiz, 1829 characteristics such as large population sizes and high migration capabilities could result in panmictic populations along river basins (Revaldaves et al 1997;Sivasundar et al 2001;Aguirre-Pabón et al 2013). Obviously, the presence of obstacles limiting or preventing gene flow can cause genetic differentiations, such as those obtained for P. lineatus (Garcez et al 2011) and P. costatus (Barroca et al 2012) populations separated by dams in Neotropical River basins.…”

Over the past few decades, South American Rivers, including the Paraná River system, have been intensely impacted by dam constructions. To mitigate adverse impacts, fish passages were incorporated into two large dams on the Paraná River (Itaipu and Porto Primavera) to reestablish longitudinal connectivity, which is very important for conserving populations of migratory fish species. The aim of this study was to estimate genetic diversity, population differentiation and gene flow, using microsatellites markers and mitochondrial haplotypes (D-loop), in populations of Prochilodus lineatus, a long distance migratory species commonly found in Paraná River basin drainages. Samples were obtained from six locations in the Upper and Middle Paraná River: Porto Primavera Reservoir, downstream of the Porto Primavera Reservoir, four tributaries of this reservoir (Pardo, Peixe, Verde and Aguapeí Rivers) and in the Iguaçu River, downstream of the Itaipu dam. High genetic diversity was observed in all samples, as expected for species with large population sizes and high migration rates. However, the influence of other factors, such as secondary contacts, fish passages and restocking were also suggested. In general, evidence of spatial population structuring was not found, even though there were two large dams in the study area. This could also be attributed to the brief period that has elapsed since the dams were built, the influence of migratory and reproductive patterns and the possible contributory effects of the fish passages. Furthermore, the absence of population structuring also corroborates existing information that emphasizes the importance of unimpeded tributaries for conserving migratory fish populations in fragmented watersheds.

“…To test if the populations of C. hippos follow a pattern of isolation by distance, a correlation analysis among the values of Φst and the geographical distance estimated in Google Earth was performed (Aguirre-Pabón, Narváez Barandica, & Castro García, 2013). The statistical significance was quantified by means of the non-parametric test Mantel after 10 000 permutations in Arlequin Ver 3.0 (Excofer, Smouse, & Quattro, 1992).…”

“…Tajimas' D compares two estimates of mutation parameters (θ) being from a non-coding region that is not exposed to selection. Significant values of D may occur owing to expansion processes, bottlenecks and selection, in conditions where there has been no selective advantage among haplotypes (Rand, 1996;Aguirre-Pabon et al, 2013). The Fu'Fs test compares the number of haplotypes observed with the number of haplotypes expected in a random sample under the assumption of an infinite model without recombination.…”

Abstract:The crevalle jack Caranx hippos, has a wide distribution in the Western Atlantic, becoming one of the most economically important species in the artisanal fishing industry in Colombia. However, little is known about its biology. The present study aimed to evaluate the variation and genetic structure of C. hippos in the Colombian Caribbean by analyzing the mitochondrial DNA region control and cytochrome oxidase subunit (COI). We sequenced the DNA of 153 muscle samples collected from specimens obtained from six fishing ports. The results showed 21 haplotypes for COI and 116 haplotypes for the control region, divided into two lineages that do not exhibit a pattern of geographical distribution. For mitochondrial control region, the estimated haplotype diversity (Hd) presented relatively high values (Hd= 0.99 and = 0.1), while for COI results were Hd = 0.68 and = 0.01; the relationship between haplotype and nucleotide diversity and the neutrality test revealed that C. hippos experienced bottlenecking and a subsequent rapid population expansion. Estimates of genetic structure were low and insignificant, indicating no differentiation between samples collected from geographical isolation. This suggests that for the Colombian Caribbean there is a panmictic population of C. hippos. However, variations were found at population levels, especially in La Guajira, Turbo and San Antero, which, when compared to those included for Brazil and México, demonstrated that unique haplotypes in La Guajira are more aligned to the Brazilian populations, by means of the influence of the Caribbean Current, whilst those from Turbo and San Antero are more frequent in haplotypes originating from Mexico. Future studies should focus the understanding of these processes. Rev. Biol. Trop. 66(1): 122-135. Epub 2018 March 01.Key words: crevalle jack, population structure, mitochondrial DNA, genetic variability.The guidelines for fishing regulations and the preservation of resources are based on the biological and ecological knowledge of the target species. However, the efficient design of these guidelines depends greatly on the available information regarding the basic levels (that comprise) of biodiversity within a species, such as the genetic diversity, population structure, and interaction with other populations (Gray, 1997;Palumbi, 2003;Kenchington, Heino, & Nielsen, 2003). Therefore, its inclusion in management plans is essential for the identification of conservation entities (Roberts, 1997).Marine fishing resources are often managed under the assumption of panmixia, taking into account that their populations are genetically homogenous due to: i) the absence of geographical barriers, ii) the capacity for dispersion, iii) the tendency to have large population numbers, iv) and the migrations which influence the low level of genetic drift, delaying differentiation amongst populations (Ward, Woodwark, & Skibinski, 1994;Nesbø, Rueness, Iversen, Skagen, & Jakobsen, 2000). Despite all this, evidence of intraspecific differentiation has been ...
